Its on-chip precision out- put amplifier allows rail-to-rail output swing to be • +2.7 V to +5.5 V Analog Power Supply achieved. The DAC7574 utilizes an I2C compatible two • 12-Bit Monotonic wire serial interface supporting high-speed interface • I2C™ Interface Up to 3.4 Mbps mode with address support of up to four DAC7574s for a total of 16 channels on the bus. • Data Transmit Capability • On-Chip Output Buffer Amplifier, Rail-to-Rail The DAC7574 uses VDD and GND to set the output Operation range of the DAC. The DAC7574 incorporates a • Double-Buffered Input Register power-on-reset circuit that ensures that the DAC output powers up at zero volts and remains there until a valid • Address Support for up to Four DAC7574s write takes place to the device. The DAC7574 contains • Synchronous Update Support for up to 16 a power-down feature, accessed via the internal control Channels register, that reduces the current consumption of the • Operation From -40 °C to 105°C device to 200 nA at 5 V. • Small 10 Lead MSOP Package The low power consumption of this part in normal operation makes it ideally suited to portable battery APPLICATIONS operated equipment. The power consumption is less • Process Control than 3mW at VDD = 5 V reducing to 1 µW in power-down mode. • Data Acquisition Systems The DAC7574 is available in a 10-lead MSOP package. • Closed-Loop Servo Control • PC Peripherals • Portable Instrumentation I2C is a trademark of Philips Corporation.
