Working Principles

The LTC2626CDD#TRPBF is a digital-to-analog converter (DAC) that converts digital signals into analog voltages. It utilizes a 12-bit resolution to provide high precision and accuracy. The device operates within a supply voltage range of 2.7V to 5.5V and can withstand a wide temperature range from -40°C to +85°C.

The DAC communicates with an external microcontroller or digital interface through the CS (chip select), SCK (serial clock), and SDI (serial data input) pins. The LDAC (load DAC) pin allows for simultaneous updating of multiple DACs in a daisy-chain configuration.

The LTC2626CDD#TRPBF features a rail-to-rail output voltage range, allowing it to generate analog voltages close to the power supply rails. It also incorporates an internal reference voltage, eliminating the need for an external reference source.
