Overview
The TLV5631IDW, produced by Texas Instruments, is a 10-bit, 8-channel serial digital-to-analog converter (DAC) designed for a wide range of applications. This device is part of the TLV563x family, which includes 12-bit and 8-bit versions, all of which are pin-compatible. The TLV5631IDW features a flexible serial interface compatible with TMS320 and SPI, QSPI, and Microwire serial ports, allowing for seamless integration into various systems. It operates on a single supply voltage from 2.7 V to 5.5 V and can also be powered by two separate analog and digital power supplies. The device is implemented using a CMOS process and is available in 20-pin SOIC and TSSOP packages.
