TLV5638ID

TLV5638ID Description

The TLV5638ID from Texas Instruments is a 12-bit, dual-channel, voltage-output digital-to-analog converter (DAC) designed for precision analog signal generation. Housed in an 8-SOIC package, it features a string DAC architecture with SPI-compatible serial interface for seamless integration into digital systems. The device operates across dual analog/digital supply ranges (2.7V–3.3V or 5V), offering flexibility for mixed-voltage environments. With ±1.7 LSB INL and ±0.4 LSB DNL, it ensures high linearity and accuracy, while a fast 7µs settling time enables rapid response in dynamic applications. The TLV5638ID supports external or internal voltage reference, enhancing design versatility.
