Texas Instruments ADS833x Low-Power Serial ADCs
Texas Instruments ADS833x Low Power, 16-bit, 500k SPS Analog-to-Digital Converters (ADCs) with a unipolar, 4-to-1 multiplexer input include a 16-bit capacitor-based SAR ADC with inherent sample and hold. TI ADS833x ADCs are based on the same core and include a unipolar 8-to-1 input mux. Both the TI ADS8331 and ADS8332 offer a high-speed, wide voltage serial interface and are capable of daisy-chain operation when using multiple converters. These 16-bit Texas Instruments ADCs are available in 24-pin, 4x4 QFN, and 24-pin TSSOP packages and are fully specified for operation over the industrial -40ºC to 85ºC temperature range. ADS8331 and ADS8332 ADCs are ideal for a variety of applications, including communications, transducer interfaces, medical instruments, magnetometers, and more.
