This data sheet provides detailed information about the AD5737, including 12-bit resolution and monotonicity, dynamic power control, current output ranges, user-programmable offset and gain, on-chip diagnostics, on-chip reference, -40°C to +105°C temperature range.
The AD5737 is a quad‑channel, 12‑bit current‑output DAC that operates from a 10.8 V to 33 V supply. It features dynamic power control for thermal management, selectable output current ranges (0 mA‑24 mA), and HART‑compatible CHART pins for process‑control networking.
The device uses a 3‑wire serial interface compatible with SPI, QSPI, Microwire, and other standards, offering optional CRC‑8 error checking and a watchdog timer. Detailed specifications cover accuracy, timing, power consumption, and DC‑DC conversion, making the AD5737 suitable for actuator control, PLCs, and HART network applications.
