AD9289BBC

Analog To Digital Converters (ADC) Overview

The AD9289BBC is a quad 8-bit, 65 MSPS analog-to-digital converter (ADC) fabricated by Analog Devices Inc. in a 64-ball mini-BGA package. It operates from a single 3.0 V supply and features serial LVDS digital outputs with data rates up to 520 Mbps. The device includes an on-chip sample-and-hold circuit and supports internal or external voltage references. Key electrical specifications include a differential input voltage range of 1 Vp-p to 2 Vp-p, a full power analog bandwidth of 300 MHz, and a typical signal-to-noise ratio (SNR) of 47.7 dB at 65 MSPS. Power dissipation is rated at 550 mW under standard operating conditions.

Analog To Digital Converters (ADC) Feature Summary

• Integrates four independent ADCs within a compact space-saving package.
• Features serialized LVDS outputs with integrated data clock and frame clock generation.
• Includes an internal clock duty cycle stabilizer for consistent performance across varying input clock duty cycles.
• Supports power-down mode to minimize energy consumption when inactive.

Analog To Digital Converters (ADC) Procurement Notes

Verify the component status as discontinued through official Analog Devices channels before design finalization. Confirm that the specific BGA-64 package variant matches the required footprint for the target PCB layout. Ensure compliance with RoHS directives if applicable to the manufacturing region. Validate that the industrial temperature range meets the operational environment requirements.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring multiple low-power, high-speed digitization channels in a small form factor. Consider the 8-bit resolution and 65 MSPS sampling rate against system dynamic range requirements. Evaluate the need for external drivers or reference components based on the specific analog input configuration and desired SNR performance levels.
