MAX5174 - 12-Bit DACs

General Description

The MAX5174/MAX5176 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 MAX5174 operates from a single +5V supply, and the MAX5176 operates from a single +3V 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 MAX5174/MAX5176 incorporate a proprietary onchip circuit that keeps the output vol.

19-1475; Rev 0; 4/99 Low-Power, Serial, 12-Bit DACs with Voltage Output General Description The MAX5174/MAX5176 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 MAX5174 operates from a single +5V supply, and the MAX5176 operates from a single +3V 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 output voltage state of either 0 or midscale. The 3-wire, digital, serial interface is compatible with SPI™/QSPI™, and MICROWIRE™ standards.
