Its on-chip precision output amplifier allows rail-to-rail output swing. The • Power-On Reset to Zero DAC5573 utilizes an I 2C-compatible two-wire serial • 2.7-V to 5.5-V Analog Power Supply interface supporting high-speed interface mode with • 8-Bit Monotonic address support of up to sixteen DAC5573s for a total • I 2C™ Interface up to 3.4 Mbps of 64 channels on the bus. • Data Transmit Capability The DAC5573 requires an external reference voltage • Rail-to-Rail Output Buffer Amplifier to set the output range of the DAC. The DAC5573 incorporates a power-on-reset circuit that ensures • Double-Buffered Input Register that the DAC output powers up at zero volts and • Address Support for up to Sixteen DAC5573s remains there until a valid write takes place in the • Synchronous Update for up to 64 Channels device. The DAC5573 contains a power-down fea- • Voltage Translators for all Digital Inputs ture, accessed via the internal control register, that reduces the current consumption of the device to 200 • Operation From –40 °C to 105°C nA at 5 V. • Small 16 Lead TSSOP Package The low power consumption of this part in normal operation makes it ideally suited to portable battery operated equipment. The power consumption is less • Process Control than 3 mW at VDD = 5 V reducing to 1 µW in • Data Acquisition Systems power-down mode. • Closed-Loop Servo Control The DAC5573 is available in a 16-lead TSSOP • PC Peripherals package. • Portable Instrumentation Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
