Overview
The AD5735ACPZ, manufactured by Analog Devices Inc., is a quad-channel voltage and current output Digital-to-Analog Converter (DAC). This device is designed to operate with a wide power supply range from -26.4 V to +33 V, making it versatile for various industrial applications. The AD5735 features on-chip dynamic power control, which minimizes package power dissipation in current mode by regulating the output driver voltage between 7.4 V and 29.5 V using a dc-to-dc boost converter. This converter is optimized for minimum on-chip power dissipation, enhancing thermal management.
The device uses a 3-wire serial interface compatible with standard SPI, QSPI, MICROWIRE, DSP, and microcontroller interface standards, operating at clock rates up to 30 MHz. Additional features include optional CRC-8 packet error checking and a watchdog timer to monitor interface activity.
