The 500-kSPS ADS8331 and ADS8332 are successive approximation register (SAR) analog-to-digital converters (ADC) with true, 16-bit no missing code (NMC) precision performance. The four- and eight-channel converters operate from a 2.7-V to 5.5-V power supply and combine high channel count and high resolution to meet the requirements of multi-channel data acquisition applications, including test and measurement, portable, industrial and medical. The ADS8331 is a low-power, 16-bit, 500k samples-per-second (SPS) analog-to-digital converter (ADC) with a unipolar, 4-to-1 multiplexer (mux) input. The device includes a 16-bit capacitor-based successive approximation register (SAR) ADC with inherent sample and hold. The ADS8332 is based on the same core and includes a unipolar 8-to-1 input mux. Both devices offer a high-speed, wide-voltage serial interface and are capable of daisy-chain operation when multiple converters are used. These converters are available in 24-pin, 4×4 QFN and 24-pin TSSOP(1) packages and are fully specified for operation over the industrial –400C to +850 C temperature range…
