MAX5354/MAX5355 19-1167 Rev 1 2/97 10-Bit Voltage-Output DACs in 8-Pin MAX General Description Features The MAX5354/MAX5355 combine a low-power, voltage- 10-Bit DAC with Configurable Output Amplifier output, 10-bit digital-to-analog converter (DAC) and a +5V Single-Supply Operation (MAX5354) precision output amplifier in an 8-pin MAX or DIP pack- +3.3V Single-Supply Operation (MAX5355) age. The MAX5354 operates from a single +5V supply, Low Supply Current: 0.28mA Normal Operation and the MAX5355 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 MAX5354/MAX5355 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 MAX5355 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 PART* TEMP.
