Product Summary
The ADS8345E/2K5 is an 8-channel, 16-bit, sampling Analog-to-Digital (A/D) converter with a synchronous serial interface. Typical power dissipation is 8mW at a 100 kHz throughput rate and a +5V supply. The reference voltage (VREF) can be varied between 500mV and VCC/2, providing a corresponding input voltage range of ±VREF. The device includes a shutdown mode which reduces power dissipation to under 15μW. The ADS8345E/2K5 is ensured down to 2.7V operation. The applications of the ADS8345E/2K5 include data acquisition, test and measurement equipment, industrial process control, personal digital assistants, and battery-powered systems.
