AD7243BR-REEL

Overview

The AD7243BR-REEL is a 12-bit voltage output digital-to-analog converter (DAC) from Analog Devices, packaged in a 16-lead SOIC. It integrates an on-chip Zener voltage reference and a buffered output amplifier capable of driving +10 V across a 2 kΩ load. The device supports single or dual supply operation, providing selectable unipolar ranges (0 V to +5 V, 0 V to +10 V) and a bipolar range (±5 V). It features a serial interface with a 300 kHz update rate and includes a clear function for power-on reset.

Feature Summary

12-bit resolution with ±1/2 LSB maximum nonlinearity over temperature
Integrated 5 V internal reference and buffered output amplifier
Serial interface supporting daisy-chaining via SDO output
Three selectable output ranges: 0–5 V, 0–10 V, and ±5 V

Applications

Process control systems
Industrial automation equipment
Digital signal processing input/output ports

Procurement Notes

Verify the specific suffix 'BR-REEL' against current manufacturer documentation to confirm package type and tape-and-reel configuration. Ensure compatibility with existing PCB footprints for the 16-SOIC package. Check for any recent product lifecycle changes or obsolescence notices directly from Analog Devices before finalizing procurement plans.

Selection Notes

Select this component when a monolithic 12-bit DAC with integrated reference and amplifier is required. It is suitable for applications needing a 3-wire serial interface and simultaneous multi-DAC updates via daisy-chaining. Consider the 10 µs settling time and 300 kHz update rate for system timing requirements. Verify that the required output voltage range matches the available configurations.

Part Context

The AD7243 belongs to the DACPORT family of complete digital-to-analog converters. It is fabricated using Linear Compatible CMOS (LC2MOS) technology. The BR variant specifically denotes the industrial temperature range (-40°C to +85°C) and the SOIC package style. This part number represents a specific packaging option within the broader AD7243 series.
