AD9640ABCPZRL7-80

Analog To Digital Converters (ADC) Overview

The AD9640ABCPZRL7-80 is a dual-channel, 14-bit analog-to-digital converter (ADC) from Analog Devices. It operates at a maximum sampling rate of 80 MSPS with an internal clock divider supporting integer divisions from 1 to 8. The device utilizes a multistage differential pipelined architecture and requires a single 1.8 V analog supply (AVDD/DVDD). Digital outputs are configurable for 1.8 V or 3.3 V CMOS logic, or 1.8 V LVDS. Key performance metrics include a signal-to-noise ratio (SNR) of 72.5 dB at 2.3 MHz input frequency and a spurious-free dynamic range (SFDR) of 87 dBc under the same conditions. The component is housed in a 64-lead LFCSP package.

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 operating temperature range of -40°C to +85°C. Confirm that the 80 MSPS speed grade meets the system timing requirements before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this variant when a maximum sampling rate of 80 MSPS is sufficient for the application bandwidth. Consider the 1.8 V analog supply requirement and verify that the host system can provide stable power rails. Evaluate the need for LVDS versus CMOS outputs based on downstream FPGA or processor interface capabilities.

Analog To Digital Converters (ADC) Part Context

This component belongs to the AD9640 family of dual 14-bit high-speed ADCs. Other variants in the series offer higher sampling rates such as 105 MSPS, 125 MSPS, and 150 MSPS. The AD9640 is designed for communications applications requiring low cost, small size, and versatility.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives within the Analog Devices portfolio include the AD9627, AD9627-11, and AD9600. These devices offer lower resolution options (12-bit, 11-bit, or 10-bit) and may serve as migration paths for systems requiring reduced bit depth.
