Texas Instruments ADS8382IBRHPR

Description
The ADS8382 is a high-performance 18-bit, 600-kHz analog-to-digital converter (ADC) with fully differential, pseudo-bipolar input. It features an 18-bit capacitor-based SAR ADC with inherent sample and hold. The ADS8382 offers a high-speed CMOS serial interface with clock speeds up to 40 MHz. It includes an onboard reference buffer, a 4.096-V reference, and an onboard conversion clock. The device has zero latency, a wide digital supply, and low power consumption.
