GENERAL DESCRIPTION  
PRODUCT HIGHLIGHTS  
The AD6640 is a high speed, high performance, low power,  
monolithic 12-bit analog-to-digital converter. All necessary  
functions, including track-and-hold (T/H) and reference, are  
included on-chip to provide a complete conversion solution.  
The AD6640 runs on a single 5 V supply and provides CMOS  
compatible digital outputs at 65 MSPS.  
1. Guaranteed sample rate is 65 MSPS.  
2. Fully differential analog input stage specified for frequencies  
up to 70 MHz; enables IF sampling.  
3. Low power dissipation: 710 mW off a single 5 V supply.  
4. Digital outputs may be run on 3.3 V supply for easy interface  
to digital ASICs.  
Specifically designed to address the needs of multichannel,  
multimode receivers, the AD6640 maintains 80 dB spurious-  
free dynamic range (SFDR) over a bandwidth of 25 MHz.  
Noise performance is also exceptional: typical signal-to-noise  
ratio is 68 dB.  
5. Complete solution: reference and track-and-hold.  
6. Packaged in small, surface-mount 44-lead plastic LQFP.  
The AD6640 is built on Analog Devices’ high speed complemen-  
tary bipolar process (XFCB) and uses an innovative multipass  
architecture. Units are packaged in a 44-lead plastic quad flatpack  
(LQFP) specified from –40°C to +85°C.
