Overview
The TLV5639IDW is a 12-bit digital-to-analog converter (DAC) produced by Texas Instruments. It features a microprocessor-compatible parallel interface and operates within a wide supply voltage range of 2.7 V to 5.5 V. This DAC is designed for single-supply operation and is available in 20-pin SOIC and TSSOP packages, catering to both commercial and industrial temperature ranges.
The device incorporates a resistor string architecture with a rail-to-rail output buffer, ensuring stable and fast settling times. It also includes an on-chip programmable precision voltage reference, which can be used as a system reference, and supports power-down modes to optimize power consumption.
