ADS8372 (ACTIVE)

16-Bit 600KSPS Serial ADC with Ref and Pseudo Bipolar, Fully Differential Input

 

Description

The ADS8372 is a high performance 16-bit, 600-kHz A/D converter with fully differential, pseudo-bipolar input. The device includes an 16-bit capacitor-based SAR A/D converter with inherent sample and hold. The ADS8372 offers a high-speed CMOS serial interface with clock speeds up to 40 MHz.

The ADS8372 is available in a 28 lead 6 × 6 QFN package and is characterized over the industrial -40°C to 85°C temperature range.
