Overview
The AD5361BCPZ from Analog Devices Inc. is a 16-channel, 14-bit serial input, voltage-output digital-to-analog converter (DAC). This device is available in a 56-lead LFCSP package and is designed for high precision and flexibility in various applications. It features a high-speed 4-wire serial interface compatible with SPI, QSPI, MICROWIRE, and DSP interface standards, supporting clock speeds up to 50 MHz.
The AD5361BCPZ offers buffered voltage outputs with a span four times the reference voltage, and each DAC can be independently trimmed for gain and offset. The device operates over a wide supply range, making it suitable for a variety of industrial and instrumentation applications.
