GENERAL DESCRIPTION
The AD5413 is a single-channel, 14-bit voltage and current
output, digital-to-analog converter (DAC) that operates within
a power supply range from a −33 V minimum on the AVSS pin
to a +33 V maximum on the AVDD1 pin. The CHART pin enables a
highway addressable remote transducer (HART®) signal to be
ac-coupled on the current output.
The AD5413 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.
The SPI interface has an optional SPI cyclic redundancy check
(CRC). The AD5413 implements improved diagnostic features
from earlier versions of similar DACs.
PRODUCT HIGHLIGHTS
1. 14-bit performance.
2. ±0.3% FSR TUE with internal reference.
3. Voltage or current output on the same pin.
4. Range of diagnostic features.
