Product Overview
AD6640ASTZ is a single-channel 12-bit pipelined ADC produced by Analog Devices. It supports fixed 65 MSPS sampling rate and built-in track-and-hold circuit for high-frequency IF signal sampling. Differential input design reduces common-mode noise and harmonic distortion, with typical 68 dB SNR and 80 dB SFDR at 31 MHz input signal. It operates on single 4.75V~5.25V analog supply, digital outputs support 3.3V or 5V logic level. The LQFP-44 package fits communication receivers, radar signal processing and high-speed test measurement equipment.
Core Advantages
Single-Chip Track-and-Hold Circuit
No external sampling circuit required, supports high intermediate frequency signal collection to simplify front-end PCB layout.
Low Distortion Differential Input
Differential signal input suppresses ground interference, maintains stable dynamic performance under continuous high-speed sampling.
Wide Industrial Temperature Range
-40°C to +85°C operating temperature range, suitable for outdoor communication and industrial measurement equipment.
Standard Parallel CMOS Output
Universal parallel digital interface, compatible with mainstream FPGA and MCU hardware platforms.
