AD9643BCPZRL7-170

Analog To Digital Converters (ADC) Overview

The AD9643BCPZRL7-170 is a dual-channel, 14-bit analog-to-digital converter (ADC) from Analog Devices Inc., operating at a maximum sampling rate of 170 MSPS. It features a multistage differential pipelined architecture with integrated output error correction logic and an internal voltage reference. The device supports flexible analog input ranges from 1.4 V p-p to 2.0 V p-p and utilizes LVDS outputs compliant with ANSI-644 levels. Powered by single 1.8 V supplies for both analog and digital sections, it includes an integer 1-to-8 input clock divider, a duty cycle stabilizer, and serial port control via SPI. The component is housed in a 64-lead LFCSP package and operates within the industrial temperature range of −40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix RL7 against official documentation to confirm reel packaging specifications. Ensure compatibility with the required sample rate grade, as the base model supports multiple speed options. Confirm that the 64-lead LFCSP thermal requirements are met through proper PCB ground plane connection for optimal heat dissipation.

Analog To Digital Converters (ADC) Selection Notes

Select this variant when a 170 MSPS conversion rate is sufficient for the target intermediate frequency bandwidth. Consider the pin compatibility with AD9613, AD6649, and AD6643 if migration from other resolutions or families is planned. Evaluate power consumption requirements, noting that standby and power-down modes offer significant energy savings compared to full operation.
