AD5423
Overview
The AD5423 is a single-channel, voltage and current output digi- tal-to-analog converter (DAC) that operates with a power supply range from The CHART p-i3n3eVnambliensimaumhigohnwAaVy SaSdtdore+s3s3abVlemraexmimotuemtraonnsAdVuDcDe1r®. (HART) signal to be coupled on the current output. The AD5423 uses a versatile, 4-wire, serial peripheral interface (SPI) that operates at clock rates of up to 50 MHz and is compatible with standard SPI, QSPI™, MICROWIRE™, digital signal processor (DSP), and microcontroller interface standards.
