Overview
The LTC2614IGN#PBF is a quad 14-bit digital-to-analog converter (DAC) produced by Analog Devices Inc. This component is part of the LTC2604/LTC2614/LTC2624 family, which includes quad DACs with different resolution levels. The LTC2614IGN#PBF is housed in a 16-lead narrow SSOP package and operates over a voltage range of 2.5V to 5.5V.
This DAC is designed for applications requiring high precision and reliability, with features such as rail-to-rail voltage output and a power-on reset circuit that ensures the voltage outputs remain at zero scale until a valid write and update take place.
