The MAX5354/MAX5355 combine a low-power, voltage-output, 10-bit digital-to-analog converter (DAC) and a precision output amplifier in an 8-pin µMAX or DIP package. The MAX5354 operates from a single +5V supply, and the MAX5355 operates from a single +3.3V supply. Both devices draw less than 280µA of supply current. 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 SPI™/QSPI™ and 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 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 opto-couplers.
The MAX5354 and MAX5355 combine a low‑power 10‑bit digital‑to‑analog converter with a precision output amplifier in an 8‑pin µMAX or DIP package. The MAX5354 runs from a single +5 V supply, while the MAX5355 runs from a single +3.3 V supply, and both draw less than 280 µA in normal operation. Features include a configurable output amplifier, software‑controlled shutdown, and serial interfaces compatible with SPI/QSPI and Microwire.
The datasheet provides absolute maximum ratings, electrical characteristics, typical operating curves, pin configurations, and layout recommendations. It also describes the serial‑interface protocol, shutdown behavior, and example circuits such as a digitally programmable current source.
