AD5755-1 Datasheet | Analog Devices

Data Sheet Quad Channel, 16-Bit, Serial Input, 4 m A to 20 m A and Voltage Output DAC, Dynamic Power Control, HART Connectivity Features 16-bit resolution and monotonicity achieved by regulating the voltage on the output driver from 7.4 V to 29.5 V using a dc-to-dc boost converter optimized for minimum Dynamic power control for thermal management Current and voltage output pins connectable to a single terminal Current output ranges: 0 m A to 20 m A, 4 m A to 20 m A, or 0 m A to 24 m A ±0.05% total unadjusted error (TUE) maximum Voltage output ranges (with 20% overrange): 0 V to 5 V, 0 V to 10 V, ±5 V, and ±10 V ±0.04% total unadjusted error (TUE) maximum User programmable offset and gain on-chip power dissipation. Each channel has a corresponding CHART pin so that HART signals can be coupled onto the current output of the AD5755-1. The device uses a versatile 3-wire serial interface that operates at clock rates of up to 30 MHz and is patible with standard SPI, QSPI™, MICROWIRE™, DSP, and microcontroller interface standards. The interface also Features optional CRC-8 packet error checking, as well as a watchdog timer that monitors activity on the interface.
