Overview
The TLV5619IPWRG4 is a 12-bit voltage output Digital-to-Analog Converter (DAC) produced by Texas Instruments. This device features a microprocessor and TMS320 compatible parallel interface, making it highly versatile for various applications. The DAC operates on a single supply voltage ranging from 2.7 V to 5.5 V and is known for its low power consumption, with typical power dissipation of 8 mW at 5 V and 4.3 mW at 3 V. The power consumption can be further reduced to 50 nW in power-down mode. The output voltage is buffered by a ×2 gain rail-to-rail amplifier, which includes a Class A output stage to enhance stability and reduce settling time.
