Overview
The AD5553CRMZ-REEL7 is a precision, low-power, 14-bit digital-to-analog converter (DAC) produced by Analog Devices Inc. This device is designed for applications requiring high accuracy and a compact form factor. It operates from a single 5V supply with a ±10V multiplying reference, which determines the full-scale output current. The AD5553CRMZ-REEL7 features an internal feedback resistor (RFB) that facilitates voltage conversion when used with an external operational amplifier. The device uses a high-speed, 3-wire serial data interface compatible with microcontrollers, utilizing serial data in (SDI), clock (CLK), and chip select (CS) pins.
