AD9634BCPZRL7-250

Analog To Digital Converters (ADC) Overview

The AD9634BCPZRL7-250 is a 12-bit, single-channel analog-to-digital converter (ADC) from Analog Devices Inc., operating at a maximum sampling rate of 250 MSPS. It utilizes a multistage differential pipelined architecture with integrated output error correction logic and an internal voltage reference. The device features flexible analog input ranges from 1.4 V p-p to 2.0 V p-p and LVDS outputs compliant with ANSI-644 levels. Powered by 1.8 V supplies for both analog and digital sections, it consumes 360 mW at full speed. The component is housed in a 32-lead LFCSP package and operates within an industrial temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing this part number. Confirm that the AD9634-250 speed grade matches the required 250 MSPS conversion rate for the target design. Ensure the ordering documentation explicitly references the Analog Devices datasheet for the AD9634 series to validate pinout and electrical specifications against the final production requirements.

Analog To Digital Converters (ADC) Selection Notes

Select the AD9634BCPZRL7-250 when a 12-bit resolution and 250 MSPS sampling rate are required for wideband applications. Consider the pin compatibility with the AD9642 if future migration to 14-bit resolution is anticipated. Evaluate the power-down modes for energy savings in standby conditions. Verify that the LVDS output drivers meet the interface requirements of the downstream processing components.

Analog To Digital Converters (ADC) Part Context

The AD9634BCPZRL7-250 belongs to the AD9634 family of high-speed analog-to-digital converters. This series includes variants with different maximum sampling rates, specifically 170 MSPS and 210 MSPS, alongside the 250 MSPS version. All variants share the same 32-lead LFCSP package and architectural features, differing primarily in their specified performance limits at higher frequencies.

Analog To Digital Converters (ADC) Replacement Considerations

The AD9634BCPZ-250 is a tray-packaged equivalent of the same functional device. The AD9634BCPZRL7-210 and AD9634BCPZRL7-170 offer lower sampling rates but maintain pin compatibility.
