MAX535/MAX5351 19-1124 Rev 1 12/96 Low-Power, 13-Bit Voltage-Output DACs with Serial Interface General Description Features The MAX535/MAX5351 combine a low-power, voltage- 13-Bit DAC with Configurable Output Amplifier output, 13-bit digital-to-analog converter (DAC) and a +5V Single-Supply Operation (MAX535) precision output amplifier in an 8-pin MAX or DIP pack- +3.3V Single-Supply Operation (MAX5351) age. The MAX535 operates from a single +5V supply Low Supply Current: 0.24mA Normal Operation and the MAX5351 operates from a single +3.3V supply. 2A Shutdown Mode Both devices draw only 280A of supply current. 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 0V sensing, and high output current capability. This makes SPI/QSPI and Microwire Compatible the MAX535/MAX5351 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 either SPI/ QSPI or Microwire. The DAC has a double-buffered input, organized as an input register followed by a DAC register. A 16-bit serial word loads data into the input Ordering Information register. The DAC register can be updated indepen- dently or simultaneously with the input register. All logic INL PART TEMP. RANGE PIN-PACKAGE inputs are TTL/CMOS-logic compatible and buffered (LSB) with Schmitt triggers to allow direct interfacing to opto- MAX535ACPA 0C to +70C 8 Plastic DIP 1/2 couplers.
