LTC2642AIDD-16#TRPBF

Overview

The LTC2642AIDD-16#TRPBF is a 16-bit unbuffered voltage output digital-to-analog converter (DAC) from Analog Devices. It operates on a single 2.7V to 5.5V supply with a typical current consumption of 120µA. The device guarantees monotonic operation over temperature and features ±1LSB INL and DNL errors. It utilizes a 3-wire SPI/MICROWIRE compatible serial interface with clock rates up to 50MHz. The part includes an asynchronous CLR pin and power-on reset circuitry that sets the output to midscale upon initialization. It is housed in a 10-lead 3mm × 3mm DFN package.

Feature Summary

16-bit resolution with ±1LSB INL/DNL guaranteed over temperature
Low 120µA supply current with 1µs settling time
Asynchronous CLR pin and Power-On Reset to midscale
50MHz SPI/QSPI/MICROWIRE compatible serial interface

Applications

High resolution offset and gain adjustment
Process control and industrial automation
Automatic test equipment
Data acquisition systems

Procurement Notes

Verify the ordering suffix #TRPBF indicates tape and reel packaging, distinct from tube packaging. Confirm the 'I' grade corresponds to the -40°C to +85°C operating range. Ensure the 'A' grade specifies the tighter ±1LSB linearity performance required for the application.

Selection Notes

Select this model for bipolar applications requiring external amplification using the internal matched scaling resistors. The unbuffered output requires loads greater than 60kΩ to maintain specified linearity. Verify compatibility with the system's reference voltage range of 2V to VDD.

Part Context

This component belongs to the LTC2642 family of 16-/14-/12-bit DACs. The 'A' designation denotes enhanced accuracy specifications compared to standard grades. The 'IDD' suffix identifies the industrial temperature range (-40°C to +85°C) and the 10-lead DFN package format specific to the dual-channel or bipolar variant architecture.
