AD7243BNZ

Overview

The AD7243BNZ is a 12-bit voltage output digital-to-analog converter (DAC) from Analog Devices, part of the DACPORT series. 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, offering selectable output ranges of 0 V to +5 V, 0 V to +10 V, and ±5 V. It features a versatile 3-wire serial interface with a maximum update rate of 300 kHz and includes a daisy-chain capability via SDO. Packaged in a 16-lead DIP or SOIC, it operates within an industrial temperature range of -40°C to +85°C.

Feature Summary

Integrated 12-bit DAC with on-chip 5 V reference and buffered output amplifier
Three selectable output voltage ranges: 0–5 V, 0–10 V, and ±5 V
Serial interface supporting up to 300 kHz update rate and daisy-chaining
CLR function for power-on reset to known output state

Applications

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

Procurement Notes

Verify the specific grade suffix 'B' against the datasheet specifications table to confirm the relative accuracy and error parameters for the industrial temperature range. Ensure the ordering information matches the required package type, as the AD7243 is available in both 16-lead DIP and SOIC configurations.

Selection Notes

Select this component when a monolithic 12-bit DAC with integrated reference and amplifier is required. Choose the bipolar configuration only if dual supplies are available. Verify that the system clock allows for the 300 kHz update rate and check if the daisy-chain feature simplifies multi-DAC wiring.

Part Context

The AD7243 belongs to the DACPORT family of complete digital-to-analog converters. These devices are designed to reduce system complexity by integrating functions typically found in multichip designs onto a single LC2MOS CMOS chip. The AD7243BNZ specifically denotes the B-grade version intended for industrial temperature applications.
