Overview
The AD5453YRMZ is a 14-bit high bandwidth multiplying digital-to-analog converter (DAC) produced by Analog Devices Inc. This device is part of the AD5450/AD5451/AD5452/AD5453 family, which includes 8-, 10-, 12-, and 14-bit current output DACs, respectively. The AD5453YRMZ operates from a 2.5 V to 5.5 V power supply, making it suitable for various applications, including battery-powered devices. It is manufactured on a CMOS submicron process, offering excellent 4-quadrant multiplication characteristics up to 12 MHz.
The device features a double-buffered, 3-wire serial interface compatible with SPI, QSPI, MICROWIRE, and most DSP interface standards. Upon power-up, the internal shift register and latches are filled with 0s, and the DAC output is at zero scale. The external reference input voltage determines the full-scale output current, and the device can handle ±10 V inputs on the reference despite operating from a single-supply power supply.
