16 位、伪双极全差动输入、250kSPS 串行输出、2.7V 至 5.5V 微功耗采样 ADC - ADS8317


The ADS8317 is a 16-bit, sampling, analog-to-digital (A/D) converter specified for a supply voltage range from 2.7V to 5.5V. It requires very little power, even when operating at the full data rate. At lower data rates, the high speed of the device enables it to spend most of its time in the power-down mode. For example, the average power dissipation is less than 0.2mW at a 10kHz data rate.

The ADS8317 offers excellent linearity and very low noise and distortion. It also features a synchronous serial (SPI/SSI-compatible) interface and a differential input. The reference voltage can be set to any level within the range of 0.1V to VDD/2.

Low power and small size make the ADS8317 ideal for portable and battery-operated systems. It is also an excellent fit for remote data-acquisition modules, simultaneous multichannel systems, and isolated data acquisition. The ADS8317 is available in MSOP-8 and SON-8 packages. The SON package size is the same as a 3x3 QFN package.
