Product Details
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 spurious-free 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.
APPLICATIONS
- Cellular/PCS Base Stations
- Multichannel, Multimode Receivers
- GPS Anti-Jamming Receivers
