The AD6640 is a high speed, high performance, low power,monolithic 12-bit analog-to-digital converter. All necessaryfuncTIons, including track-and-hold (T/H) and reference, areincluded on-chip to provide a complete conversion soluTIon.The AD6640 runs on a single 5 V supply and provides CMOScompaTIble digital outputs at 65 MSPS.Specifically designed to address the needs of mulTIchannel,multimode receivers, the AD6640 maintains 80 dB spuriousfreedynamic range (SFDR) over a bandwidth of 25 MHz.Noise performance is also exceptional: typical signal-to-noiseratio is 68 dB.The AD6640 is built on Analog Devices’ high speed complementarybipolar process (XFCB) and uses an innovative multipassarchitecture. Units are packaged in a 44-lead plastic quad flatpack(LQFP) specified from –40°C to +85°C.
