MAX5352/MAX5353 19-1196 Rev 0 2/97 Low-Power, 12-Bit Voltage-Output DACs with Serial Interface General Description Features The MAX5352/MAX5353 combine a low-power, voltage- 12-Bit DAC with Configurable Output Amplifier output, 12-bit digital-to-analog converter (DAC) and a +5V Single-Supply Operation (MAX5352) precision output amplifier in an 8-pin MAX or DIP pack- +3.3V Single-Supply Operation (MAX5353) age. The MAX5352 operates from a single +5V supply, Low Supply Current: 0.28mA Normal Operation and the MAX5353 operates from a single +3.3V supply. Both devices draw less than 280A of supply current. 2A Shutdown Mode The output amplifiers inverting input is available to the Available in 8-Pin MAX user, allowing specific gain configurations, remote Power-On Reset Clears DAC Output to Zero sensing, and high output current capability. This makes SPI/QSPI and Microwire Compatible the MAX5352/MAX5353 ideal for a wide range of appli- cations, including industrial process control. Other fea- Schmitt-Trigger Digital Inputs for Direct tures include a software shutdown and power-on reset. Optocoupler Interface The serial interface is compatible with SPI/QSPI +3.3V MAX5353 Directly Interfaces with +5V Logic and Microwire. The DAC has a double-buffered input, organized as an input register followed by a DAC regis- ter. A 16-bit serial word loads data into the input regis- ter. The DAC register can be updated independently or Ordering Information simultaneously with the input register. All logic inputs are TTL/CMOS-logic compatible and buffered with Schmitt triggers to allow direct interfacing to opto- INL PART* TEMP. RANGE PIN-PACKAGE (LSB) couplers.
