Overview
The AD9653BCPZRL7-125 is a quad, 16-bit, 125 MSPS 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 125 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 device is available in a RoHS-compliant, 48-lead LFCSP package and is specified over the industrial temperature range of −40°C to +85°C.
