AD9627ABCPZ-125

Analog To Digital Converters (ADC) Overview

The AD9627ABCPZ-125 is a dual-channel, 12-bit analog-to-digital converter (ADC) from Analog Devices Inc., operating at a maximum sampling rate of 125 MSPS. It utilizes a multistage differential pipelined architecture with integrated output error correction logic. The device operates on a single 1.8 V analog supply and supports digital output driver supplies ranging from 1.8 V to 3.3 V for CMOS or 1.8 V for LVDS configurations. Key performance metrics include a Signal-to-Noise Ratio (SNR) of 69.4 dBc at 70 MHz input frequency and a Spurious-Free Dynamic Range (SFDR) of 85 dBc under the same conditions. Power consumption is specified at 750 mW at the maximum sampling rate.

Analog To Digital Converters (ADC) Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status and lead times directly with the manufacturer or certified suppliers prior to procurement. Ensure storage conditions adhere to moisture sensitivity level requirements to prevent package damage during soldering processes.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a dual-channel, high-speed 12-bit ADC is required for communications applications. Consider the specific power supply requirements for the DRVDD pin if interfacing with 3.3 V logic families. Evaluate the need for LVDS versus CMOS outputs based on system noise immunity and trace length constraints.

Analog To Digital Converters (ADC) Part Context

This component belongs to the AD9627 family of dual 12-bit analog-to-digital converters. The suffix '125' indicates the maximum sampling speed variant. Other variants in the series include speeds of 80 MSPS, 105 MSPS, and 150 MSPS. The device shares pin compatibility with related parts like the AD9640 and AD9600 for migration purposes.

Analog To Digital Converters (ADC) Replacement Considerations

The AD9627BCPZ-125 is listed as a historical equivalent in revision history notes, though current ordering guides may reference updated part numbers. Verify pinout and electrical specifications against the AD9627-150 or AD9627-105 if higher or lower sampling rates are acceptable.
