Replacement verdict
Compatible functional replacement candidate
The ADS131E06IPAGR is a viable functional replacement candidate for the ADS131A04IPBS in applications where a higher channel count is beneficial and the wider supply range and industrial temperature grade are acceptable. Both devices share a compatible TQFP-64 footprint and SPI interface, but the ADS131A04IPBS offers a wider supply voltage range and hardware-based security features, while the ADS131E06IPAGR provides two additional channels and a higher maximum data rate. Designers should validate the channel count, supply rail compatibility, and specific timing requirements against the target application before finalizing the substitution.

Key electrical and mechanical differences between the two devices
| Parameter | ADS131A04IPBS | ADS131E06IPAGR | Why it matters |
|---|---|---|---|
| Number of ADC channels | 4 | 6 | Channel count determines how many independent signals can be measured simultaneously; a 6-channel part cannot directly replace a 4-channel part if more inputs are needed, and vice versa affects board layout. |
| Resolution | 24 bit | 24 bit | Both are 24-bit delta-sigma converters, so dynamic range and precision class are comparable, supporting similar high-accuracy measurement applications. |
| Maximum sample rate (per channel) | 128 kSPS | 64 kSPS | Sample rate limits the bandwidth of signals that can be captured; the higher-rate device supports faster transient capture, while the slower one may be insufficient for high-frequency monitoring. |
| Interface type | SPI (with CRC and daisy-chain support) | SPI | Both use SPI, but feature differences such as CRC and daisy-chaining affect system robustness and multi-device wiring, influencing firmware and board design compatibility. |
| Supply voltage (analog) | 3.0 V to 3.6 V (single supply) | 2.7 V to 5.25 V (analog) | Analog supply range affects input signal swing and compatibility with the surrounding analog front end; a wider range offers more flexibility but may require different regulation. |
| Package | TQFP-32 | TQFP-64 | Package footprint and pin count must match the PCB layout; different packages are not drop-in compatible and require a board redesign. |
| Operating temperature range | -40 °C to +125 °C | -40 °C to +105 °C | The temperature range determines suitability for harsh environments; the wider-rated device can be used in higher-temperature applications where the other may be marginal. |
| Integrated PGA / input configuration | Integrated PGA with flexible input multiplexer | Integrated PGA with input multiplexer | On-chip gain and input routing affect the ability to interface directly with small sensors; differences in flexibility influence external signal-conditioning requirements. |
| Typical application focus | Energy metering, power monitoring, industrial sensing | ECG/EEG biopotential, industrial monitoring | Application focus reflects optimized noise, filtering, and input characteristics; substituting across these domains may degrade performance in the target application. |

Frequently asked questions
What are the primary differences between the ADS131A04IPBS and the ADS131E06IPAGR?
The ADS131A04IPBS is a 4-channel, simultaneous-sampling, 24-bit delta-sigma ADC with a maximum data rate of 128 kSPS per channel, housed in a TQFP-32 package. The ADS131E06IPAGR is a 6-channel, simultaneous-sampling, 24-bit delta-sigma ADC with a maximum data rate of 64 kSPS per channel, housed in a TQFP-64 package. The ADS131A04IPBS targets higher per-channel throughput with fewer channels, while the ADS131E06IPAGR provides more channels at a lower per-channel data rate.
Are the ADS131A04IPBS and ADS131E06IPAGR pin-to-pin compatible?
No. The ADS131A04IPBS uses a 32-pin TQFP package, while the ADS131E06IPAGR uses a 64-pin TQFP package. The differing pin counts and package footprints mean they are not pin-to-pin compatible and cannot be interchanged on the same PCB land pattern without redesign.
How do the channel counts and data rates compare between these two ADCs?
The ADS131A04IPBS provides 4 simultaneous-sampling channels at up to 128 kSPS per channel. The ADS131E06IPAGR provides 6 simultaneous-sampling channels at up to 64 kSPS per channel. Selection depends on whether the application prioritizes higher per-channel sampling rate (ADS131A04IPBS) or a greater number of channels (ADS131E06IPAGR).
Do both devices support simultaneous sampling of all channels?
Yes. Both the ADS131A04IPBS and the ADS131E06IPAGR are simultaneous-sampling delta-sigma ADCs, meaning all of their respective channels (4 for the ADS131A04IPBS and 6 for the ADS131E06IPAGR) are sampled at the same instant, which is important for multi-phase power monitoring and other phase-coherent measurement applications.
What are the supply voltage requirements for the ADS131A04IPBS and ADS131E06IPAGR?
Both devices operate from an analog supply (AVDD) of 3.0 V to 3.6 V and a digital supply (DVDD) of 1.8 V to 3.6 V, with a separate digital I/O supply (IOVDD) of 1.8 V to 3.6 V. Designers should confirm exact limits against the respective manufacturer datasheets before finalizing the power tree.
Which device is better suited for higher-channel-count applications?
The ADS131E06IPAGR is better suited for higher-channel-count applications because it provides 6 simultaneous-sampling channels versus 4 on the ADS131A04IPBS. However, the ADS131E06IPAGR has a lower maximum per-channel data rate of 64 kSPS, so applications requiring both many channels and high per-channel throughput may need multiple devices or a different part.
Can the ADS131A04IPBS and ADS131E06IPAGR share the same SPI interface design?
Both devices use an SPI-compatible serial interface for configuration and data readout, but the register maps, command sets, and frame formats differ between the two product families. Firmware and driver code written for one device cannot be reused directly on the other without modification and revalidation against the respective datasheet.
What package and temperature range do these two ADCs support?
The ADS131A04IPBS is offered in a TQFP-32 package, and the ADS131E06IPAGR is offered in a TQFP-64 package. Both are specified for the industrial temperature range of -40°C to +85°C, making them suitable for industrial measurement, power monitoring, and instrumentation applications.
