ADS8380 (ACTIVE)

18-Bit 600KSPS Serial ADC with Ref and Unipolar Pseudo Diff Input

 

Description

The ADS8380 is a high performance 18-bit, 600-kHz A/D converter with single-ended (pseudo-differential) input. The device includes an 18-bit capacitor-based SAR A/D converter with inherent sample and hold. The ADS8380 offers a high-speed CMOS serial interface with clock speeds up to 40 MHz.

The ADS8380 is available in a 28 lead 6 × 6 QFN package and is characterized over the industrial –40°C to 85°C temperature range.
