AD5410 Current Source DAC IC Chip

AD5410(Single Channel, 16-Bit, Serial Input,Current Source DAC)

Introduction

The AD5410/AD5420 is a low-cost, precision, fully integrated 12/16-bit converter offering a programmable current source output designed to meet the requirements of industrial process control applications.The output current range is programmable to 4mA to 20 mA, 0mA to 20mA or an over range function of 0mA to 24mA. The output is open circuit protected and can drive inductive loads of 1H. The device is specified to operate with a power supply range from 10.8 V to 40V（AD5410/AD5420AREZ) or 10.8V to 60V( AD5410/AD5420ACPZ). Output loop compliance is 0 V to AVDD-2.5 V.

The flexible serial interface is SPI and MICRO WIRE compatible and can be operated in 3-wire mode to minimize the digital isolation required in isolated applications.

The device also includes a power-on-reset function ensuring that the device powers up in a known state and an asynchronous CLEAR pin which sets the output to the low end of the selected current range.

The total output error is typically ±0.1% FSR.
