Replacement verdict
Compatible functional replacement candidate
The AD5410AREZ and AD5412AREZ are functionally compatible single-channel 12-bit 4-20 mA current-loop DACs sharing the same TSSOP-24 package and pinout, with the AD5412AREZ adding HART signal injection and voltage output capability. The AD5412AREZ can serve as a drop-in replacement for the AD5410AREZ in 4-20 mA current-loop applications, provided the additional voltage-output and HART features are not required to be disabled or are acceptable in the target design.

Key electrical and mechanical differences between the two devices
| Parameter | AD5410AREZ | AD5412AREZ | Why it matters |
|---|---|---|---|
| Resolution | 12 bit | 12 bit | Both devices provide 12-bit DAC resolution, so output granularity is equivalent. |
| Number of DAC Channels | 1 | 1 | Single-channel architecture means both parts target the same single-loop control applications. |
| Output Type | Current output | Current and voltage output | The AD5412AREZ can drive both current and voltage outputs, while the AD5410AREZ is current-only, affecting loop and voltage-mode compatibility. |
| Output Current Range | 4 mA to 20 mA, 0 mA to 20 mA, 0 mA to 24 mA | 4 mA to 20 mA, 0 mA to 20 mA, 0 mA to 24 mA | Identical current ranges allow direct substitution in 4-20 mA and 0-20 mA current-loop designs. |
| Output Voltage Range | Not available | 0 V to 5 V, 0 V to 10 V, ±5 V, ±10 V | Only the AD5412AREZ supports voltage output, which is essential for voltage-mode control interfaces. |
| Supply Voltage | 10.8 V to 40 V | 10.8 V to 40 V | Matching supply ranges mean both parts can operate from the same industrial power rails. |
| Interface | SPI | SPI | Both use a serial SPI interface, simplifying firmware and digital isolation reuse. |
| Package | 24-Lead TSSOP | 24-Lead TSSOP | Identical package and pin count support drop-in PCB compatibility. |
| Operating Temperature Range | -40°C to +105°C | -40°C to +105°C | Same industrial temperature range ensures both parts meet the same environmental requirements. |

Frequently asked questions
What are the main differences between the AD5410AREZ and AD5412AREZ?
The AD5410AREZ is a single-channel, 12-bit current-output DAC with a 4 mA to 20 mA output range. The AD5412AREZ is a single-channel, 12-bit voltage and current output DAC that provides both a 4 mA to 20 mA current output and a 0 V to 5 V or 0 V to 10 V voltage output, offering greater output flexibility than the AD5410AREZ.
Do the AD5410AREZ and AD5412AREZ share the same package and pinout?
Both devices are offered in a 24-lead TSSOP package (RE-24 suffix) and are pin-compatible, allowing the AD5412AREZ to be used as a drop-in replacement for the AD5410AREZ when the additional voltage output capability is required.
What is the resolution and accuracy specification of these DACs?
Both the AD5410AREZ and AD5412AREZ are 12-bit DACs. The AD5410AREZ offers relative accuracy of ±0.024% FSR (typical) and the AD5412AREZ offers relative accuracy of ±0.024% FSR (typical) for the current output and ±0.024% FSR (typical) for the voltage output, as specified in the Analog Devices datasheets.
What supply voltages do the AD5410AREZ and AD5412AREZ require?
Both devices operate from a single AVDD supply of 10.8 V to 40 V for the current output, and the AD5412AREZ additionally requires a AVSS supply of -10.8 V to -40 V (or can be operated with AVSS = 0 V for unipolar voltage output). A separate DVDD supply of 2.7 V to 5.5 V is used for the digital interface on both parts.
Can the AD5410AREZ and AD5412AREZ be used in HART communication applications?
Yes. Both the AD5410AREZ and AD5412AREZ include a HART-compatible interface pin that allows a HART signal to be superimposed on the current output, making them suitable for industrial process control applications requiring HART communication.
What is the operating temperature range for the AD5410AREZ and AD5412AREZ?
Both devices are specified for operation over the industrial temperature range of -40°C to +105°C, as stated in the Analog Devices datasheets.
Which device should be selected for applications requiring both voltage and current outputs?
The AD5412AREZ should be selected because it integrates both a 12-bit voltage output (0 V to 5 V or 0 V to 10 V) and a 12-bit current output (4 mA to 20 mA), while the AD5410AREZ provides only the 4 mA to 20 mA current output.
Are the AD5410AREZ and AD5412AREZ pin-compatible with each other for direct replacement?
Yes. Both devices use the same 24-lead TSSOP package and pinout, so the AD5412AREZ can directly replace the AD5410AREZ on an existing PCB when the additional voltage output function is needed, provided the system supply and firmware support the AD5412AREZ features.
