AD9634BCPZ-210

Analog To Digital Converters (ADC) Overview

The AD9634BCPZ-210 is a single-channel, 12-bit analog-to-digital converter (ADC) from Analog Devices Inc., operating at a sampling rate of 210 MSPS. It utilizes a multistage differential pipelined architecture with integrated output error correction logic. The device features a wide bandwidth input supporting user-selectable ranges from 1.4 V p-p to 2.0 V p-p, with a nominal full-scale input of 1.75 V p-p. Power is supplied via separate 1.8 V AVDD and DRVDD rails, resulting in a typical power consumption of 360 mW at maximum speed. Digital outputs are provided as DDR LVDS data pairs compliant with ANSI-644 levels. Configuration is managed through a 3-wire SPI-compatible serial interface.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific speed grade suffix matches the required sampling rate before procurement. Confirm that the LFCSP-32 package thermal requirements align with the target PCB layout. Ensure the ordering code corresponds to the exact Analog Devices part number to avoid functional mismatches between different speed grades within the same family.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and 210 MSPS throughput are required for communication applications. Consider the AD9634-250 variant if higher sampling rates up to 250 MSPS are needed, or the AD9634-170 for lower power consumption at reduced speeds. Evaluate the SNR and SFDR specifications against the input frequency requirements to ensure adequate dynamic range for the specific signal environment.

Analog To Digital Converters (ADC) Part Context

The AD9634BCPZ-210 belongs to the AD9634 series of high-speed, low-power ADCs designed for communications. It shares pin compatibility with the AD9642, allowing designers to migrate from 12-bit to 14-bit architectures without changing the board layout. The device is specified over the industrial temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Replacement Considerations

The AD9634BCPZ-170 and AD9634BCPZ-250 are direct pin-compatible replacements within the same family, differing only in maximum sampling rates. For 14-bit upgrades, the AD9642BCPZ offers identical footprint and pinout compatibility.
