MAX5170 - 14-Bit DACs

General Description

The MAX5170/MAX5172 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 MAX5170 operates from a +5V single supply and the MAX5172 operates from a +3V single supply.

Key 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/CMOS-compatible and are internally buffered with Schmitt triggers to allow direct interfacing to optocouplers. The MAX5170/MAX5172 incorporate a proprietary on-chip circuit that keeps the output vo.

19-1478; Rev 0; 4/99 Low-Power, Serial, 14-Bit DACs with Voltage Output General Description The MAX5170/MAX5172 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 MAX5170 operates from a +5V single supply and the MAX5172 operates from a +3V single supply. Both devices draw only 280µA of supply current, which reduces to 1µA in shutdown. In addition, the programmable power-up reset feature allows for a user-selectable power-up output voltage of either 0 or midscale. The 3-wire serial interface is compatible with SPI™, QSPI™, and MICROWIRE™ standards.
