LTC1654 Dual 14-Bit Rail-to-Rail DAC in 16-Lead SSOP Package

The LTC®1654 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 3.5µs or 8µs respectively and supply currents of 750µA and 450µA in the two modes. The LTC1654 also has shutdown capability, power-on reset and a clear function to 0V
