The ADS8327 is a low power, 16-bit, 500-kSPS analog-to-digital converter with a unipolar input. The device includes a 16-bit capacitor-based SAR A/D converter with inherent sample and hold. The ADS8328 is based on the same core and includes a 2-to-1 input MUX with programmable option of TAG bit output. Both the ADS8327 and ADS8328 offer a high-speed, wide voltage serial interface and are capable of chain mode operation when multiple converters are used. These converters are available in a 16-lead TSSOP or 4×4 QFN packages and are fully specified for operation over the industrial –40°C to +85°C temperature range.
