Replacement verdict
Compatible functional replacement candidate
The AD9200ARSZ and AD9201ARSRL are both 10-bit CMOS analog-to-digital converters from Analog Devices in a 28-lead SSOP package, sharing core resolution and footprint characteristics. However, they differ in channel architecture and sampling rate, so the AD9201ARSRL can serve as a functional substitute only where the dual-channel configuration and lower maximum sample rate are acceptable. Designers should validate timing, input drive, and channel requirements against the target application before committing to the substitution.

Key electrical and mechanical differences between the two devices
| Parameter | AD9200ARSZ | AD9201ARSRL | Why it matters |
|---|---|---|---|
| Number of A/D Converters | 1 | 2 | A dual converter can process two input channels simultaneously, while a single converter requires external multiplexing for multi-channel systems. |
| Resolution | 10 bit | 10 bit | Resolution determines the quantization granularity; both parts match here, so accuracy class is equivalent. |
| Sampling Rate | 20 MSPS | 20 MSPS | Maximum sample rate defines the input bandwidth the converter can support; identical rates mean similar signal bandwidth capability. |
| Input Type | Differential, Single-Ended | Differential, Single-Ended | Input configuration affects analog front-end design and achievable noise performance; matching types ease substitution. |
| Supply Voltage | 2.7 V to 5.5 V | 2.7 V to 5.5 V | Supply range determines compatibility with system power rails; identical ranges allow drop-in power design reuse. |
| Package / Case | 28-SSOP | 28-SSOP | Package footprint and pinout govern PCB layout compatibility; matching packages simplify board-level substitution. |
| Operating Temperature Range | -40°C to +85°C | -40°C to +85°C | Temperature range defines environmental robustness; identical ratings mean equivalent application suitability. |
| Power Consumption per Channel | Approx. 100 mW | Approx. 100 mW per channel | Power per channel affects thermal budget and supply sizing; the dual-channel part doubles total dissipation for two channels. |
| Pin Count | 28 | 28 | Pin count influences package compatibility and routing; equal counts support similar layout strategies. |

Frequently asked questions
What are the key differences between the AD9200ARSZ and the AD9201ARSRL?
The AD9200ARSZ is a single 10-bit, 20 MSPS analog-to-digital converter, while the AD9201ARSRL is a dual 10-bit, 20 MSPS ADC. The AD9200ARSZ is supplied in a 28-lead SSOP package, whereas the AD9201ARSRL is supplied in a 28-lead SSOP package in tape-and-reel form. The AD9201ARSRL integrates two AD9200-type converter cores for I/Q or dual-channel sampling.
Are the AD9200ARSZ and AD9201ARSRL pin-compatible?
No. The AD9200ARSZ is a single-channel 10-bit ADC in a 28-lead SSOP, while the AD9201ARSRL is a dual-channel 10-bit ADC in a 28-lead SSOP. Because the AD9201ARSRL contains two converter channels, the pin functions and internal signal routing differ from the single-channel AD9200ARSZ, so they are not direct pin-for-pin replacements.
What is the maximum sampling rate of each device?
Both the AD9200ARSZ and the AD9201ARSRL are specified for a maximum sampling rate of 20 MSPS per channel, based on Analog Devices datasheet specifications.
What resolution do the AD9200ARSZ and AD9201ARSRL provide?
Both devices provide 10-bit resolution. The AD9200ARSZ delivers 10-bit conversion on a single channel, and the AD9201ARSRL delivers 10-bit conversion on each of its two channels.
What package and packing options distinguish the AD9200ARSZ from the AD9201ARSRL?
The AD9200ARSZ is offered in a 28-lead SSOP package in tube or standard tray form, while the AD9201ARSRL is the tape-and-reel variant of the AD9201 in a 28-lead SSOP package. The "RL" suffix on the AD9201ARSRL denotes tape-and-reel packing for automated assembly.
Can the AD9200ARSZ be used as a drop-in replacement for the AD9201ARSRL?
No. The AD9200ARSZ is a single-channel ADC, while the AD9201ARSRL is a dual-channel ADC. They differ in channel count, pin functions, and internal architecture, so a direct drop-in substitution is not possible without redesigning the signal path and PCB layout.
What are typical applications for the AD9200ARSZ versus the AD9201ARSRL?
The AD9200ARSZ is typically used in single-channel digitization such as imaging, video, and general-purpose data acquisition. The AD9201ARSRL, with its two matched 10-bit channels, is suited to I/Q demodulation, dual-channel sampling, and applications requiring simultaneous sampling of two signals.
