AFEx81H1 Low-Power Digital-to-Analog Converters

Texas Instruments AFEx81H1 Low-Power Digital-to-Analog Converters (DACs) are highly integrated, high-accuracy, extremely low-power DACs with voltage outputs designed for HART-enabled sensor-transmitter applications. The AFEx81H1 devices include most components required to create a 4mA to 20mA, 2-wire (loop-powered) sensor transmitter. With the highly accurate DAC, these parts include a HART-certified FSK modem, 10ppm/°C voltage reference, and a diagnostic analog-to-digital converter (ADC). An external voltage-to-current conversion and power regulation are required to accommodate intrinsic and functional safety concerns.
