LTC2642IDD-16#TRPBF

Overview

The LTC2642IDD-16#TRPBF is a 16-bit unbuffered voltage output digital-to-analog converter (DAC) from Analog Devices, housed in a 10-lead 3mm × 3mm DFN package. It operates on a single 2.7V to 5.5V supply with a typical current consumption of 120µA. The device features a 3-wire SPI/MICROWIRE compatible serial interface supporting clock rates up to 50MHz. Key electrical specifications include ±1LSB INL and ±0.5LSB DNL over temperature, a 1µs settling time, and a glitch impulse of 0.5nV•sec. The part includes internal matched scaling resistors for bipolar operation and an asynchronous clear pin.

Feature Summary

16-bit resolution with guaranteed monotonicity over temperature
Unbuffered voltage output with low offset error of ±1LSB
Internal matched scaling resistors enable bipolar output configuration
Power-on reset clears DAC output to midscale upon initial power application

Applications

Process control and industrial automation systems
Automatic test equipment requiring high precision
Data acquisition systems needing low power consumption

Procurement Notes

Verify the ordering suffix #TRPBF indicates tape and reel packaging, distinct from tube packaging. Confirm the IDD suffix corresponds to the industrial temperature range (-40°C to +85°C). Ensure the specific lot date code meets project requirements as manufacturing dates vary by batch.

Selection Notes

Select this model for applications requiring bipolar output capability via external amplifiers, unlike the LTC2641 which is unipolar only. The 16-bit resolution is suitable for high-precision tasks where ±1LSB INL is required. Consider the unbuffered output impedance when designing load circuits to maintain linearity specifications.

Part Context

This component belongs to the LTC2642 family of 16-/14-/12-bit VOUT DACs. The 'I' designation specifies the industrial temperature grade, while 'DD' identifies the 10-lead DFN package. The '#TRPBF' suffix denotes lead-free finish and tape-and-reel shipping format.
