Overview
The DAC7571IDBVR, manufactured by Texas Instruments, is a low-power, single-channel, 12-bit digital-to-analog converter (DAC) with a buffered voltage output. It features an on-chip precision output amplifier that enables rail-to-rail output swing, making it suitable for a wide range of applications. The DAC7571IDBVR operates with a power supply range of +2.7 V to +5.5 V and consumes minimal power, with a typical current of 140 µA at 5 V. It also includes a power-on-reset circuit that ensures the DAC output starts at zero volts until a valid write operation is performed.
