AD9628BCPZ-105

Analog To Digital Converters (ADC) Overview

The AD9628BCPZ-105 is a dual-channel, 12-bit analog-to-digital converter (ADC) from Analog Devices Inc., operating at a maximum sampling rate of 105 MSPS. It utilizes a multistage differential pipeline architecture with output error correction logic to ensure no missing codes across the full industrial temperature range of −40°C to +85°C. The device features a high-performance sample-and-hold circuit and an on-chip voltage reference, powered by a single 1.8 V supply. Key electrical specifications include a signal-to-noise ratio (SNR) of 71.2 dBFS at a 70 MHz input frequency and a spurious-free dynamic range (SFDR) of 93 dBc under the same conditions. It supports both 1.8 V CMOS and LVDS digital output formats.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix BCPZ corresponds to the RoHS-compliant LFCSP package variant when sourcing. Confirm that the -105 designation aligns with the 105 MSPS maximum conversion rate specification rather than the higher speed variant. Ensure the procurement documentation references the Rev. C datasheet for accurate pinout and electrical parameter validation prior to integration.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring dual-channel acquisition with 12-bit resolution at moderate high speeds. The device is suitable where system cost minimization is critical due to its integrated reference and low power consumption of 101 mW per channel. Consider the available serial port interface for configuration flexibility and the support for programmable digital test patterns for system verification during development phases.

Analog To Digital Converters (ADC) Part Context

This part belongs to the AD9628 family of dual-channel ADCs, which are pin-compatible with other Analog Devices converters such as the AD9650, AD9269, and AD9258. This compatibility allows for migration paths between different bit resolutions ranging from 10-bit to 16-bit within the same form factor. The device is designed to support sampling rates from 20 MSPS up to 125 MSPS depending on the specific sub-model selected.
