AD9627BCPZ11-105

Analog To Digital Converters (ADC) Overview

The AD9627BCPZ11-105 is a dual, 11-bit, 105 MSPS analog-to-digital converter (ADC) from Analog Devices. It features 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 interfaces. Key performance metrics at 105 MSPS include an SNR of 65.8 dBc and SFDR of 85 dBc at 70 MHz input frequency. Power consumption is specified at 600 mW under typical conditions. The ADC includes flexible analog input ranges, an internal voltage reference, and a clock duty cycle stabilizer.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet revision to confirm pinout compatibility and electrical specifications. Ensure that the design accounts for the exposed paddle thermal pad requirement in the LFCSP package to maintain optimal thermal performance and reliability during soldering.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 11-bit resolution is sufficient for the application, offering a migration path from 10-bit or 14-bit devices within the same family. Consider the 105 MSPS maximum conversion rate and the specific power requirements associated with the chosen digital output mode (CMOS vs. LVDS) when designing the power supply rails.

Analog To Digital Converters (ADC) Part Context

This part belongs to the AD9627-11 series, which is designed for communications applications requiring low cost and small size.
