a +2.5 V to +5.5 V, 230 ␮A, Dual Rail-to-Rail Voltage Output 8-/10-/12-Bit DACs AD5303/AD5313/AD5323* GENERAL DESCRIPTION FEATURES AD5303: Two Buffered 8-Bit DACs in One Package AD5313: Two Buffered 10-Bit DACs in One Package AD5323: Two Buffered 12-Bit DACs in One Package 16-Lead TSSOP Package Micropower Operation: 300 ␮ A @ 5 V (Including Reference Current) Power-Down to 200 nA @ 5 V, 50 nA @ 3 V +2.5 V to +5.5 V Power Supply Double-Buffered Input Logic Guaranteed Monotonic By Design Over All Codes Buffered/Unbuffered Reference Input Options Output Range: 0–VREF or 0–2 V REF Power-On-Reset to Zero Volts SDO Daisy-Chaining Option Simultaneous Update of DAC Outputs via LDAC Pin Asynchronous CLR Facility Low Power Serial Interface with Schmitt-Triggered Inputs On-Chip Rail-to-Rail Output Buffer Amplifiers APPLICATIONS Portable Battery Powered Instruments Digital Gain and Offset Adjustment Programmable Voltage and Current Sources Programmable Attenuators The AD5303/AD5313/AD5323 are dual 8-, 10- and 12-bit buffered voltage output DACs in a 16-lead TSSOP package that operate from a single +2.5 V to +5.5 V supply consuming 230 µA at 3 V. Their on-chip output amplifiers allow the outputs to swing rail-to-rail with a slew rate of 0.7 V/µs. The AD5303/ AD5313/AD5323 utilize a versatile 3-wire serial interface that operates at clock rates up to 30 MHz and is compatible with standard SPI™, QSPI, MICROWIRE™ and DSP interface standards. The references for the two DACs are derived fro...
