AD9650BCPZ-25

Analog To Digital Converters (ADC) Overview

The AD9650BCPZ-25 is a dual-channel, 16-bit analog-to-digital converter (ADC) operating at a maximum sampling rate of 25 MSPS. It features a multistage differential pipelined architecture with integrated output error correction logic and shared voltage reference. The device supports input frequencies up to 300 MHz with a 2.7 V p-p analog input range. It operates from a single 1.8 V supply for both analog and digital sections. Key performance metrics include an SNR of 83 dBFS at 9.7 MHz input and an SFDR of 95 dBc under the same conditions. Power consumption is 119 mW per channel at 25 MSPS. The component is housed in a 64-lead LFCSP package and functions within an industrial temperature range of −40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix BCPZ indicates the lead-free LFCSP-64 package variant. Confirm that the -25 designation corresponds strictly to the 25 MSPS conversion rate model. Ensure the ordering information matches the manufacturer's current datasheet revision to avoid discrepancies in pinout or electrical specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a 25 MSPS sampling rate is sufficient for the application bandwidth. Consider the 16-bit resolution and high dynamic range requirements. Evaluate the 1.8 V supply compatibility against system power rails. Check if the parallel CMOS or LVDS output interface meets the downstream processing requirements.

Analog To Digital Converters (ADC) Part Context

This component belongs to the AD9650 family of dual-channel ADCs. Other variants in the series include models supporting 65 MSPS, 80 MSPS, and 105 MSPS rates. All variants share the same 64-lead LFCSP package and architectural features, differing primarily in maximum sampling speed and associated AC performance characteristics.

Analog To Digital Converters (ADC) Replacement Considerations

The AD9650BCPZ-65, AD9650BCPZ-80, and AD9650BCPZ-105 are pin-compatible alternatives offering higher sampling rates. The AD9268 is also listed as pin-compatible within the same package.
