Replacement verdict
Compatible functional replacement candidate
The AD5410AREZ-REEL7 and AD5412AREZ share the same 24-lead TSSOP footprint, 4 mA to 20 mA current output architecture, and industrial temperature range, making them functionally interchangeable in many designs. However, the AD5412AREZ adds voltage output capability and HART communication support, so validation is required to confirm whether the additional features are needed or if the simpler AD5410AREZ-REEL7 meets the application requirements.

Key electrical and mechanical differences between the two devices
| Parameter | AD5410AREZ-REEL7 | AD5412AREZ | Why it matters |
|---|---|---|---|
| Resolution | 12 bit | 12 bit | Determines the smallest analog output step; both are 12-bit, so quantization granularity is equivalent. |
| Number of DAC Channels | 1 | 1 | Channel count defines how many independent analog outputs are available; both provide a single channel. |
| Output Type | Current | Current / Voltage | The AD5412 can source either current or voltage outputs, while the AD5410 is current-only, affecting loop or voltage-mode compatibility. |
| Output Current Range | 4 mA to 20 mA | 4 mA to 20 mA; 0 mA to 20 mA; 0 mA to 24 mA | Selectable current ranges allow the AD5412 to support additional industrial current-loop configurations beyond the fixed 4–20 mA of the AD5410. |
| Output Voltage Range | Not available | 0 V to 5 V; 0 V to 10 V; ±5 V; ±10 V | Voltage output capability in the AD5412 enables direct voltage-mode control, which the current-only AD5410 cannot provide. |
| Supply Voltage | 10.8 V to 40 V (AVDD) | 10.8 V to 40 V (AVDD) | Wide compliance range supports industrial field supplies; identical ratings mean similar power-supply design constraints. |
| Interface | SPI | SPI | Both use a serial SPI interface, so host controller firmware and timing requirements are largely interchangeable. |
| Package / Mounting | 24-Lead TSSOP, Surface Mount | 24-Lead TSSOP, Surface Mount | Identical package and mounting simplify PCB footprint reuse and drop-in replacement considerations. |
| Operating Temperature Range | -40°C to +105°C | -40°C to +105°C | Matching industrial temperature ranges ensure both parts are suitable for the same harsh environments. |

Frequently asked questions
What are the key differences between the AD5410AREZ-REEL7 and the AD5412AREZ?
The AD5410 is a single-channel, 12-bit current-output DAC with a 4 mA to 20 mA output range. The AD5412 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. The AD5412 therefore offers additional voltage-output capability that the AD5410 does not provide.
Do the AD5410AREZ-REEL7 and AD5412AREZ share the same package and pinout?
Both devices are offered in a 24-lead TSSOP package with an exposed pad. However, because the AD5412 includes an additional voltage-output function, the pin functions and external component requirements differ. Designers must consult the respective datasheets before considering any layout or pin-compatible substitution.
What is the resolution and DAC architecture of these two devices?
Both the AD5410 and AD5412 are 12-bit DACs. They use a segmented R-2R ladder architecture for the current-output mode. The AD5412 additionally includes an internal voltage-output amplifier for its voltage mode.
What output ranges are available on the AD5410AREZ-REEL7 and AD5412AREZ?
The AD5410 supports a 4 mA to 20 mA current output. The AD5412 supports a 4 mA to 20 mA current output and also provides a voltage output that can be configured for 0 V to 5 V or 0 V to 10 V, depending on the reference and gain settings.
Are the AD5410AREZ-REEL7 and AD5412AREZ pin-compatible for direct replacement?
No. Although both are 24-lead TSSOP devices, the AD5412 uses additional pins for its voltage-output function and has different internal register configurations. A direct drop-in replacement is not supported without verifying pin functions, external components, and firmware compatibility against the manufacturer datasheets.
What supply voltages and reference requirements apply to these devices?
Both devices operate from a single supply. The AD5410 and AD5412 require an external reference voltage for accurate operation. The AD5412 voltage-output mode also depends on the reference voltage and configured gain to achieve the 0 V to 5 V or 0 V to 10 V ranges. Exact supply and reference limits must be verified from the official datasheets.
Which device should be selected for an application requiring both current and voltage outputs?
The AD5412AREZ should be selected when both 4 mA to 20 mA current output and 0 V to 5 V or 0 V to 10 V voltage output are required from a single DAC channel. The AD5410AREZ-REEL7 is suitable only for applications requiring a 4 mA to 20 mA current output.
