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.
Specifically designed to address the needs of multichannel,
multimode receivers, the AD6640 maintains 80 dB spuriousfree
dynamic range (SFDR) over a bandwidth of 25 MHz.
Noise performance is also exceptional: typical signal-to-noise
ratio is 68 dB.
The AD6640 is built on Analog Devices’ high speed complementary
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.
