D A C 7 512 DAC7571 www.ti.com SLAS374D – FEBRUARY 2003 – REVISED JANUARY 2014 +2.7 V to +5.5 V, I2C INTERFACE (RECEIVE ONLY), VOLTAGE OUTPUT, 12-BIT DIGITAL-TO-ANALOG CONVERTER Check for Samples: DAC7571 FEATURES 1 2 Micropower Operation: 140 µA @ 5 V Power-On Reset to Zero +2.7-V to +5.5-V Power Supply Specified Monotonic by Design Settling Time: 10 µs to ±0.003%FS I2C™ Interface up to 3.4 Mbps On-Chip Output Buffer Amplifier, Rail-to-Rail Operation Double-Buffered Input Register Address Support for up to Two DAC7571s Small 6-Lead SOT Package Operation From –40°C to 105°C APPLICATIONS Process Control Data Acquisition Systems Closed-Loop Servo Control PC Peripherals Portable Instrumentation DESCRIPTION The DAC7571 is a low-power, single channel, 12-bit buffered voltage output DAC. Its on-chip precision output amplifier allows rail-to-rail output swing to be achieved. The DAC7571 utilizes an I2C compatible two wire serial interface that operates at clock rates up to 3.4 Mbps with address support of up to two DAC7571s on the same data bus. The output voltage range of the DAC is set to VDD. The DAC7571 incorporates a power-on-reset circuit that ensures that the DAC output powers up at zero volts and remains there until a valid write to the device takes place. The DAC7571 contains a powerdown feature, accessed via the internal control register, that reduces the current consumption of the device to 50 nA at 5 V. The low power consumption of this...
