Overview
The TLV5624IDR is an 8-bit voltage output Digital-to-Analog Converter (DAC) produced by Texas Instruments. It features a flexible 4-wire serial interface compatible with TMS320 and SPI, QSPI, and Microwire serial ports. This DAC is designed for single supply operation from 2.7 V to 5.5 V and is available in 8-pin SOIC and 8-pin MSOP packages, making it suitable for applications where board space is a concern.
The device includes a programmable internal reference and a programmable settling time, allowing designers to optimize between speed and power dissipation. The on-chip precision voltage reference can also be used as a system reference, capable of sourcing up to 1 mA. The TLV5624IDR is implemented using a CMOS process and is designed for operation in standard commercial and industrial temperature ranges.
