Overview
The AD5735ACPZ-REEL7, produced 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 and process control applications. The AD5735 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 also includes a user-programmable offset and gain, on-chip diagnostics, and an on-chip reference with a maximum drift of ±10 ppm/°C. The device operates over a temperature range of −40°C to +105°C, enhancing its reliability in harsh environments.
