Overview
The LTC2624CGN#TRPBF is a quad 12-bit rail-to-rail digital-to-analog converter (DAC) produced by Analog Devices Inc. This component is part of the LTC2604/LTC2614/LTC2624 family, which includes 16-bit, 14-bit, and 12-bit DACs, respectively. The LTC2624 is housed in a 16-lead narrow SSOP package and is designed for high-performance applications requiring precise voltage output.
The device features separate reference inputs for each DAC, built-in high-performance output buffers, and is guaranteed monotonic over the full operating temperature range. It operates on a simple SPI/MICROWIRE compatible 3-wire serial interface, supporting clock rates up to 50MHz, and includes daisy-chain capability and a hardware CLR function.
