Overview
The DAC7571IDBVT, produced by Texas Instruments, is a low-power, single-channel, 12-bit buffered voltage output Digital-to-Analog Converter (DAC). It features an on-chip precision output amplifier that allows for rail-to-rail output swing, making it suitable for a variety of applications requiring precise analog output. The DAC utilizes an I2C compatible two-wire serial interface with clock rates up to 3.4 Mbps and supports up to two DAC7571s on the same data bus. The device includes a power-on-reset circuit that ensures the DAC output starts at zero volts and remains there until a valid write command is received. Additionally, it has a power-down feature that reduces current consumption to 50 nA at 5 V, making it ideal for battery-operated equipment.
