MAX5171 - 14-Bit DACs

Description

The MAX5171/MAX5173 low-power, serial, voltage-output, 14-bit digital-to-analog converters (DACs) feature a precision output amplifier in a space-saving 16-pin QSOP package.

The MAX5171 operates from a +5V single supply, and the MAX5173 operates from a +3V single supply.

Features

  • include software and hardware shutdown, shutdown lockout, a hardware clear 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/CMOScompatible and are internally buffered with Schmitt triggers to allow direct interfacing to optocouplers. The MAX5171/MAX5173 incorporate a proprietary on-chip circuit that keeps the output vol.

19-1476; Rev 0; 4/99 Low-Power, Serial, 14-Bit DACs with Force/Sense Voltage Output General Description The MAX5171/MAX5173 low-power, serial, voltage-output, 14-bit digital-to-analog converters (DACs) feature a precision output amplifier in a space-saving 16-pin QSOP package. The MAX5171 operates from a +5V single supply, and the MAX5173 operates from a +3V single supply. The output amplifier’s inverting input is available to allow specific gain configurations, remote sensing, and high output current capability. This makes the MAX5171/ MAX5173 ideal for a wide range of applications, including industrial process control. Both devices draw only 260µA of supply current, which reduces to 1µA in shutdown mode.
