16 位高速 2.7V 到 5V 微功耗采样模数转换器 - ADS8320
 

描述

The ADS8320 device is a 16-bit, sampling analog-to-digital (A/D) converter with ensured specifications over a 2.7-V to 5.25-V supply range. It requires very little power even when operating at the full 100-kHz 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. The average power dissipation is less than 100 mW at 10-kHz data rate.

The ADS8320 also features operation from 2 V to 5.25 V, a synchronous serial (SPI/SSI compatible) interface, and a differential input. The reference voltage can be set to any level within the range of 500 mV to VCC.

Ultra-low power and small size make the ADS8320 ideal for portable and battery-operated systems. It is also a perfect fit for remote data acquisition modules, simultaneous multi-channel systems, and isolated data acquisition. The ADS8320 is available in an 8-pin VSSOP package.
