AD6640
PRODUCT DE SCRIPT ION
T he 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.
T he AD6640 runs on a single +5 V supply and provides CMOS-
compatible digital outputs at 65 MSPS.
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.
T he AD6640 is built on Analog Devices’ high speed complemen-
tary bipolar process (X FCB) and uses an innovative multipass
architecture. Units are packaged in a 44-terminal Plastic T hin
Quad Flatpack (T QFP) specified from –40
°
C to +85
°
C.
PRODUCT HIGHLIGHT S
