Texas Instruments ADS8345EB/2K5G4

Description
The ADS8345 is an 8-channel, 16-bit, sampling Analog-to-Digital (A/D) converter with a synchronous serial interface. It operates with a single supply voltage ranging from 2.7V to 5V. The reference voltage (VREF) can be adjusted between 500mV and Vcc/2, resulting in a corresponding input voltage range of ±VREF. The device features an 8-channel single-ended or 4-channel differential input configuration and supports conversion rates up to 100kHz. It includes a shutdown mode that reduces power dissipation to under 15μW. The ADS8345 is available in QSOP-20 and SSOP-20 packages and is specified for operation over the -40°C to 85°C temperature range.
