MAX5171AEEE

The MAX5171AEEE belongs to MAX5171 family. This makes the MAX5171/ MAX5173 ideal for a wide range of applications, including industrial process control. Both devices draw only 260A of supply current, which reduces to 1A in shutdown mode. In addition, the programmable power-up reset feature allows for a user-selectable output voltage of either 0 or midscale. The 3-wire serial interface is compatible with SPI, QSPI, and MICROWIREstandards. An input register followed by a DAC register provides a double-buffered input, allowing the input and DAC registers to be updated independently or simultaneously with a 16-bit serial word. Additional 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. The MAX5171/MAX5173 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 devices are available in 16-pin QSOP packages and are specified for the extended (-40°C to +85°C)temperature range. The MAX5171/MAX5173 are pin-compatible upgrades to the 12-bit MAX5175/MAX5177. For 100% pincompatible DACs with an internal reference, see the 13-bit MAX5132/MAX5133 and the 12-bit MAX5122/MAX5123 data sheets. 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. All logic inputs are TTL/CMOScompatible and are internally buffered with Schmitt triggers to allow direct interfacing to optocouplers.
