The DAC7571 is a low-power, single channel, 12-bit· Power-On Reset to Zero buffered voltage output DAC. Its on-chip precision· +2.7-V to +5.5-V Power Supply output amplifier allows rail-to-rail output swing to be· Specified Monotonic by Design achieved. The DAC7571 utilizes an I2C compatibletwo wire serial interface that operates at clock rates · Settling Time: 10 μs to ±0.003%FS up to 3.4 Mbps with address support of up to two· I2C™ Interface up to 3.4 Mbps DAC7571s on the same data bus.· On-Chip Output Buffer Amplifier, Rail-to-RailOperation The output voltage range of the DAC is set to VDD.The DAC7571 incorporates a power-on-reset circuit· Double-Buffered Input Register that ensures that the DAC output powers up at zero· Address Support for up to Two DAC7571s volts and remains there until a valid write to the· Small 6-Lead SOT Package device takes place. The DAC7571 contains a· Operation From –40°C to 105°C power-down feature, accessed via the internal controlregister, that reduces the current consumption of thedevice to 50 nA at 5 V.· Process Control The low power consumption of this part in normal· Data Acquistion Systems operation makes it ideally suited for portable battery operated equipment. The power consumption is less· Closed-Loop Servo Control than 0.7 mW at VDD = 5 V reducing to 1 μW in· PC Peripherals power-down mode.· Portable Instrumentation The DAC7571 is available in a 6-lead SOT 23package.
