AD5422BCPZ-REEL7

Digital To Analog Converters Overview

The AD5422BCPZ-REEL7 is a single-channel, 16-bit serial input digital-to-analog converter (DAC) from Analog Devices Inc., housed in a 40-lead LFCSP package. It integrates a programmable current source and voltage output for industrial process control. The device supports AVDD supply ranges of 10.8 V to 40 V and AVSS from −26.4 V to −3 V/0 V. Key specifications include ±0.01% FSR typical total unadjusted error (TUE), ±3 ppm FSR/°C current output drift, and ±2 ppm FSR/°C voltage output drift. It features an SPI/MICROWIRE-compatible interface, on-chip fault detection, and asynchronous clear functionality.

Digital To Analog Converters Feature Summary

• 16-bit resolution with guaranteed monotonicity
• Programmable current output: 4 mA to 20 mA, 0 mA to 20 mA, or 0 mA to 24 mA
• Programmable voltage output: 0 V to 5 V, 0 V to 10 V, ±5 V, or ±10 V with 10% overrange
• LFCSP package includes CAP2 pin for HART signal coupling

Digital To Analog Converters Applications

• Process controls
• Actuator controls
• PLC systems
• HART network connectivity

Digital To Analog Converters Procurement Notes

Verify the B version accuracy grade and REEL7 tape-and-reel packaging configuration against specific project requirements. Confirm that the LFCSP footprint matches the design layout, as this variant supports HART connectivity via the CAP2 pin, which differs from TSSOP versions.

Digital To Analog Converters Selection Notes

Select the AD5422BCPZ-REEL7 when 16-bit precision and HART protocol support are required. The B grade offers tighter TUE specifications compared to the A grade. Ensure the application utilizes the LFCSP package to access the CAP2 pin for HART signal injection onto the current output loop.

Digital To Analog Converters Part Context

This component belongs to the AD5412/AD5422 family of low-cost, fully integrated DACs. The AD5422 provides 16-bit resolution, whereas the AD5412 offers 12-bit resolution. Both share identical pinouts and feature sets, including the LFCSP variant's HART capability. The B suffix indicates a specific accuracy bin within the product line.

Digital To Analog Converters Replacement Considerations

The AD5422AREZ-REEL7 serves as a direct replacement if the A grade accuracy specification is sufficient for the application. For 12-bit resolution requirements, the AD5412BCPZ-REEL7 is pin-compatible but offers lower resolution.
