ADS8328 - 具有 2 到 1 MUX 的 2.7V~5.5V 16 位 500KSPS 串行 ADC - 精密ADC(<=10MSPS) - 模数转换器 - TI公司（Texas Instruments，德州仪器）
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.
