Description
The DAC7571IDBVR is a low-power, 12-bit digital-to-analog converter (DAC) from Texas Instruments. It features a single-channel output with an I²C interface, supporting a 2.7V to 5.5V supply range. Key characteristics include:
- Resolution: 12 bits
- Interface: I²C (up to 3.4 Mbps)
- Output: Voltage (buffered, rail-to-rail)
- Power Consumption: Low (0.7 mW at 5V, 0.4 mW at 3V)
- Package: SOT-23-6 (small form factor)
The DAC7571 includes a power-on-reset circuit, ensuring 0V output at startup. It’s ideal for portable devices, industrial control, and sensor calibration due to its precision and compact size. The I²C address is fixed, allowing simple single-device integration.
