Its on-chip precision output amplifier allows rail-to-rail output swing to be • +2.7-V to +5.5-V Analog Power Supply achieved. The DAC7573 utilizes an I 2C compatible • 12-Bit Monotonic two wire serial interface supporting high-speed • I 2C™ Interface up to 3.4 Mbps interface mode with address support of up to sixteen • Data Transmit Capability DAC7573s for a total of 64 channels on the bus. • On-Chip Output Buffer Amplifier, Rail-to-Rail The DAC7573 requires an external reference voltage Operation to set the output range of the DAC. The DAC7573 • Double-Buffered Input Register incorporates a power-on-reset circuit that ensures • Address Support for up to Sixteen DAC7573s that the DAC output powers up at zero volts and remains there until a valid write takes place in the • Synchronous Update Support for up to 64 device. The DAC7573 contains a power-down fea- Channels ture, accessed via the internal control register, that • Operation From –40 °C to 105°C reduces the current consumption of the device to 200 • Small 16 Lead TSSOP Package nA at 5 V. The low power consumption of this part in normal operation makes it ideally suited to portable battery • Process Control operated equipment. The power consumption is less • Data Acquisition Systems than 3 mW at VDD=5 V reducing to 1 µW in power-down mode. • Closed-Loop Servo Control • PC Peripherals The DAC7573 is available in a 16-lead TSSOP • Portable Instrumentation package.
