AD5412AREZ-REEL7

Digital To Analog Converters Overview

The AD5412AREZ-REEL7 is a single-channel, 12-bit serial input digital-to-analog converter (DAC) from Analog Devices. It integrates a programmable current source and a buffered voltage output designed for industrial process control applications. The device supports multiple output ranges, including 4 mA to 20 mA, 0 mA to 20 mA, or 0 mA to 24 mA for current, and 0 V to 5 V, 0 V to 10 V, ±5 V, or ±10 V for voltage. It features a flexible SPI/MICROWIRE-compatible interface, an internal reference with 10 ppm/°C maximum drift, and operates on AVDD supplies from 10.8 V to 40 V. The component is housed in a TSSOP-24 package.

Digital To Analog Converters Feature Summary

• 12-bit resolution with guaranteed monotonicity and typical total unadjusted error (TUE) of ±0.01% FSR.
• Programmable current output ranges: 4 mA to 20 mA, 0 mA to 20 mA, or 0 mA to 24 mA.
• Buffered voltage output with configurable ranges: 0 V to 5 V, 0 V to 10 V, ±5 V, or ±10 V.
• Integrated 5 V reference with maximum temperature coefficient of 10 ppm/°C.

Digital To Analog Converters Applications

• Industrial process control systems
• Actuator controls
• Programmable Logic Controller (PLC) modules

Digital To Analog Converters Procurement Notes

Verify the REEL7 suffix indicates tape-and-reel packaging containing 1000 units per reel. Confirm the 'A' grade designation corresponds to the specified -40°C to +85°C operating temperature range and associated accuracy specifications. Ensure the TSSOP-24 package variant matches the required PCB footprint and thermal management strategy.

Digital To Analog Converters Selection Notes

Select this component when a single-channel DAC with both current and voltage outputs is required. The AD5412 offers 12-bit resolution; for higher precision, consider the pin-compatible AD5422 which provides 16-bit resolution. Verify that the required output compliance voltage fits within the AVDD minus 2.5 V limit and that the serial interface timing meets the system clock requirements.

Digital To Analog Converters Part Context

The AD5412 belongs to the AD5412/AD5422 family of fully integrated DACs. It is pin-compatible with the AD5410 (12-bit current only), AD5420 (16-bit current only), and AD5422 (16-bit current/voltage). The LFCSP package variant includes HART connectivity capabilities via the CAP2 pin, whereas the TSSOP package used in this part number does not support HART signaling directly.

Digital To Analog Converters Replacement Considerations

The AD5422 serves as a direct pin-compatible upgrade offering 16-bit resolution. For applications requiring only current output, the AD5410 or AD5420 are compatible alternatives. External verification of register compatibility and performance specifications against the specific application requirements is necessary before substitution.
