AD9681BBCZ-125

Analog To Digital Converters (ADC) Overview

The AD9681BBCZ-125 is an octal, 14-bit analog-to-digital converter (ADC) operating at a maximum sampling rate of 125 MSPS. It integrates eight independent ADC channels within a single 10 mm × 10 mm 144-ball CSP-BGA package. The device utilizes a pipeline architecture with on-chip sample-and-hold circuits and requires a single 1.8 V power supply for both analog and digital domains. It features a 650 MHz full-power analog input bandwidth and supports differential inputs with a 2 V p-p range. Digital outputs are provided via serial LVDS interfaces, including data clock (DCO) and frame clock (FCO) outputs to facilitate high-speed data capture.

Analog To Digital Converters (ADC) Feature Summary

• Integrates eight 14-bit ADC channels in a compact footprint to minimize board space.
• Provides low power consumption of 110 mW per channel at the maximum sampling rate.
• Features flexible bit orientation and programmable clock/data alignment via SPI control.
• Includes built-in digital test pattern generation for system verification.
