This document is the AD5735 datasheet, which is a quad-channel voltage and current output DAC produced by Analog Devices. It operates with a power supply range of -26.4V to +33V and supports 12-bit resolution and dynamic power control.
The AD5735 is a quad‑channel 12‑bit DAC that provides both voltage and current outputs. It operates from a wide power‑supply range and includes on‑chip dynamic power control to reduce thermal dissipation. The device uses a 3‑wire serial interface compatible with SPI, QSPI, Microwire, DSP and other microcontroller standards, offering optional CRC‑8 error checking and a watchdog timer.
The datasheet lists detailed electrical specifications, pin configurations, timing characteristics, and layout guidelines. It also includes information on the on‑chip reference, DC‑DC converter, and options for galvanically isolated interfaces, making it suitable for process‑control and actuator‑control applications.
| Resolution | 12 Bits |
|---|---|
| Voltage Output Range | 0–5 V |
| Current Output Range | 0–24 mA |
| Power‑supply Range | –26.4 V to +33 V |
It uses a versatile 3‑wire serial interface compatible with SPI, QSPI, Microwire, DSP and other microcontroller standards, supporting up to 30 MHz clock rates and optional CRC‑8 error checking.
On‑chip dynamic power control regulates the output driver voltage via a de‑to‑de boost converter, minimizing package power dissipation.
The internal reference input voltage is 5 V with a temperature coefficient of –10 + 5 + 10 ppm/°C.
It is offered in a 64‑lead LFCSP_VQ (CP‑64‑3) chip‑scale package.
