DAC7718SPAG TI Octal 12-Bit DAC | 64-TQFP (10x10) | ±1 LSB INL, 2.7V-5.5V

Product Overview

The DAC7718SPAG is a high-performance, octal, 12-bit digital-to-analog converter (DAC) from Texas Instruments. It offers eight independent DAC channels with rail-to-rail output buffers, operating from a single 2.7V to 5.5V supply. The device features a flexible serial interface (SPI-compatible) and includes a power-on reset circuit that ensures the DAC outputs power up at zero-scale or mid-scale. Housed in a compact 64-TQFP (10x10 mm) package, the DAC7718SPAG is ideal for multi-channel applications requiring high accuracy and low power consumption.
