Rainbow Electronics MAX5355 User Manual

__________________General Description

The MAX5354/MAX5355 combine a low-power, voltageoutput, 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 optocouplers.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
