Overview
The AD5755BCPZ from Analog Devices Inc. is a quad, voltage and current output Digital-to-Analog Converter (DAC) designed for high-performance applications. It operates with a wide power supply range from −26.4 V to +33 V, making it versatile for various industrial and control systems. The device features on-chip dynamic power control, which minimizes package power dissipation in current mode by regulating the voltage on the output driver using a DC-to-DC boost converter. This DAC supports a 3-wire serial interface compatible with standard SPI, QSPI™, MICROWIRE™, DSP, and microcontroller interface standards, operating at clock rates up to 30 MHz.
