Its on-chip precision output amplifier allows rail-to-rail output swing to be • Power-On Reset to Zero achieved. The DAC5571 utilizes an I2C-compatible, • +2.7-V to +5.5-V Power Supply two-wire serial interface that operates at clock rates • Specified Monotonic by Design up to 3.4 Mbps with address support of up to two • I2C™ Interface up to 3.4 Mbps DAC5571s on the same data bus. • On-Chip Output Buffer Amplifier, Rail-to-Rail The output voltage range of the DAC is 0 V to VDD. Operation The DAC5571 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 DAC5571s volts and remains there until a valid write to the device takes place. The DAC5571 contains a • Small 6 Lead SOT 23 Package power-down feature, accessed via the internal control • Operation From –40°C to 105°C register, that reduces the current consumption of the device to 50 nA at 5 V. The low-power consumption of this part in normal • Process Control operation makes it ideally suited for portable battery • Data Acquistion Systems 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 DAC7571/6571/5571 are 12/10/8-bit, single-channel I2C DACs from the same family. DAC7574/6574/5574 and DAC7573/6573/5573 are 12/10/8-bit quad-channel I2C DACs. Also see DAC8571/8574 for single/quad-channel, 16-bit I2C DACs.
