AD9650BCPZRL7-105

Analog To Digital Converters (ADC) Overview

The AD9650BCPZRL7-105 is a dual-channel, 16-bit analog-to-digital converter (ADC) operating at a maximum sampling rate of 105 MSPS. It features a multistage differential pipelined architecture with integrated output error correction logic and a shared internal voltage reference. The device supports input frequencies up to 300 MHz with a differential analog input range of 2.7 V p-p. Key performance metrics include an SNR of 82 dBFS at 30 MHz input and 105 MSPS data rate, and an SFDR of 90 dBc under the same conditions. Power consumption is 328 mW per channel at 105 MSPS. It operates from a single 1.8 V supply for both analog and digital domains, housed in a 64-lead LFCSP package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the RL7 suffix indicates tape and reel packaging rather than tray packaging when sourcing components. Confirm the specific temperature grade and revision level match the design requirements. Ensure the supplier provides valid traceability documentation for the Analog Devices Inc. manufacturing origin. Cross-reference the ordering part number with the latest datasheet to confirm pinout compatibility.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high dynamic range and wide bandwidth signal digitization. The 105 MSPS variant is suitable for IF sampling frequencies up to 300 MHz. Consider the pin compatibility with AD9268 and other dual families if migration across resolutions is planned. Evaluate the power consumption requirements against the available thermal dissipation capabilities of the PCB layout.

Analog To Digital Converters (ADC) Part Context

This part belongs to the AD9650 series of dual 16-bit ADCs, which are available in multiple sampling rate variants including 25 MSPS, 65 MSPS, and 80 MSPS. The AD9650 family is designed for high-frequency applications and shares architectural similarities with other Analog Devices high-speed converters. The specific -105 designation denotes the maximum sampling rate capability of this particular unit within the product line.

Analog To Digital Converters (ADC) Replacement Considerations

The AD9650 is pin compatible with the AD9268, AD9269, AD9251, AD9231, and AD9204 families. These parts allow for simple migration across different resolutions and bandwidths. Verify that the alternative part meets the specific SNR and SFDR requirements of the original design before substitution.
