Overview
The AD9637BCPZ-80 is an octal, 12-bit, 40/80 MSPS analog-to-digital converter (ADC) produced by Analog Devices Inc. This ADC is designed for low cost, low power, small size, and ease of use, making it ideal for applications where dynamic performance and compact packaging are critical. It operates at a conversion rate of up to 80 MSPS and requires a single 1.8 V power supply. The ADC features an on-chip sample-and-hold circuit and supports LVPECL-, CMOS-, and LVDS-compatible sample rate clocks. It also includes features like programmable clock and data alignment, digital test pattern generation, and individual channel power-down modes.
