TLV5638CDR

TLV5638CDR Description

The TLV5638CDR from Texas Instruments is a 12-bit, dual-channel, voltage-output digital-to-analog converter (DAC) designed for precision analog signal generation. Packaged in an 8-SOIC surface-mount form factor, it supports both SPI-compatible serial interface and flexible supply voltage options (2.7V–5V for analog/digital domains). With a ±1.7 LSB INL and ±0.4 LSB DNL, it ensures high linearity and accuracy, making it suitable for applications demanding tight performance tolerances. The device features a 7µs settling time, enabling rapid response in dynamic systems. Its architecture leverages a string DAC design, providing stable output with either internal or external reference support.
