Overview
The AD9645BCPZRL7-80 is a dual, 14-bit analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is designed for low cost, low power, small size, and ease of use, making it ideal for applications where high dynamic performance and compact packaging are critical. The ADC operates at a conversion rate of up to 80 MSPS and features an on-chip sample-and-hold circuit. It requires a single 1.8 V power supply and supports LVPECL-, CMOS-, and LVDS-compatible sample rate clocks. The AD9645 is specified over the automotive temperature range of −40°C to +105°C and is available in a RoHS-compliant, 32-lead LFCSP package.
