The LTC1654 is a dual, rail-to-rail voltage output, 14-bit digital-to-analog converter (DAC). It is available in a 16-lead narrow SSOP package, making it the smallest dual 14-bit DAC available. It includes output buffer amplifiers and a flexible serial interface.
The LTC1654 has REFHI pins for each DAC that can be driven up to VCC. The output will swing from 0V to VCC in a gain of 1 configuration or VCC/2 in a gain of 1/2 configuration. It operates from a single 2.7V to 5.5V supply.
The LTC1654 has two programmable speeds: a FAST and SLOW mode with ±1LSB settling times of 3µs or 8.5µs respectively and supply currents of 930µA and 540µA in the two modes. The LTC1654 also has shutdown capability, power-on reset and a clear function to 0V.
Applications
- Digital Calibration
- Industrial Process Control

Tools & Simulations
Precision DAC Error Budget Tool
The Precision DAC Error Budget Tool is a web application that calculates the DC Accuracy of precision DAC signal chains. It shows how the static errors accumulate throughout your signal chain to quickly evaluate the design tradeoffs. Calculations include the DC errors introduced by Voltage References, Operation Amplifiers and Precision DACs.
