Single-Channel, 14-Bit Voltage and Current Output DAC with HART Connectivity Data Sheet AD5413 FEATURES GENERAL DESCRIPTION 14-bit resolution and monotonicity The AD5413 is a single-channel, 14-bit voltage and current Voltage and current output available on a single terminal output, digital-to-analog converter (DAC) that operates within Current output range: 0 mA to 24 mA, 0.3% FSR TUE maximum a power supply range from a 33 V minimum on the AVSS pin Output voltage range, trimmed: 10.5 V, 0.3% FSR TUE to a +33 V maximum on the AVDD1 pin. The CHART pin enables a Output voltage range with untrimmed overrange: 12.6 V highway addressable remote transducer (HART) signal to be (equivalent to 26% overrange at +10 V) ac-coupled on the current output. User-programmable offset and gain The AD5413 uses a versatile, 4-wire serial peripheral interface On-chip reference (SPI) that operates at clock rates of up to 50 MHz and is On-chip diagnostics compatible with standard SPI, QSPI, MICROWIRE, digital 40C to +105C temperature range signal processor (DSP), and microcontroller interface standards. 32-lead, 5 mm 5 mm, LFCSP The SPI interface has an optional SPI cyclic redundancy check APPLICATIONS (CRC). The AD5413 implements improved diagnostic features from earlier versions of similar DACs. Process control Actuator control PRODUCT HIGHLIGHTS Channel isolated analog outputs 1. 14-bit performance.
