The output amplifier's inverting input is available to the user, allowing specific gain configurations, remote sensing, and high output current capability. This makes the MAX5354/MAX5355 ideal for a wide range of applications, including industrial process control. Other features include a software shutdown and power-on reset. The serial interface is compatible with SPITM/QSPITM and MicrowireTM. 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 register. The DAC register can be updated independently or simultaneously with the input register. All logic inputs are TTL/CMOS-logic compatible and buffered with Schmitt triggers to allow direct interfacing to optocouplers.
