AFEx8101 16 & 14-Bit Low-Power DACs

Texas Instruments AFEx8101 16 and 14-Bit Low-Power Digital-to-Analog Converters (DACs) are highly-integrated, high-accuracy, extremely low-power DACs. These come with voltage outputs designed for sensor-transmitter applications. The AFEx8101 devices include most components required to create a 4mA to 20mA, 2-wire (loop-powered) sensor transmitter. In addition to the highly accurate DAC, these devices contain a 10ppm/°C voltage reference and a diagnostic analog-to-digital converter (ADC). External voltage-to-current conversion and power regulation are required to accommodate intrinsic and functional-safety concerns.
