Overview
The TLV5631IPWRG4 is a digital-to-analog converter (DAC) produced by Texas Instruments. It is part of the TLV5630, TLV5631, and TLV5632 family, which are pin-compatible, eight-channel DACs with varying resolutions. The TLV5631 specifically offers a 10-bit resolution. These DACs are designed for single-supply operation from 2.7 V to 5.5 V and can operate on two separate analog and digital power supplies. They feature a flexible serial interface compatible with TMS320 and SPI, QSPI, and Microwire serial ports, making them versatile for various applications.
