MAX5175 - Maxim

MAX5175 12-Bit DACs

The MAX5175/MAX5177 low-power, serial, voltage-output, 12-bit digital-to-analog converters (DACs) feature a precision output amplifier in a space-saving 16-pin QSOP package. The MAX5175 operates from a single +5V supply, and the MAX5177 operates from a single +3V supply. The output amplifier’s inverting input is available to allow specific gain configuration.

Features

include software and hardware shutdown, shutdown lockout, a hardware reset pin, and a reference input capable of accepting DC and offset AC signals. These devices provide a programmable digital output pin for added functionality and a serial-data output pin for daisy-chaining. All logic inputs are TTL/CMOS compatible and are internally buffered with Schmitt triggers to allow direct interfacing to optocouplers. The MAX5175/MAX5177 incorporate a proprietary on-chip circuit that keeps the output voltage virtually “glitch free,” limiting the glitches to a few millivolts during power-up. Both devic.
