Hot-selling and scarce AD6645BBC 14-Bit 80 MSPS A/D Converter 52-TQFP_EP spot stock

Product Features

The AD6645 is a high-speed, high-performance, monolithic14-bit analog-to-digital converter . All necessary functions,including track-and-hold (T/H) and reference, are included onthe chip to provide a complete conversion solution . The AD6645provides CMOS-compatible digital outputs . It is the fourth generation in a wideband ADC family, preceded by theAD9042 (12-bit, 41 MSPS), the AD6640 (12-bit, 65 MSPS,IF sampling), and the AD6644 (14-bit, 40 MSPS/65 MSPS).

Designed for multichannel, multimode receivers, the AD6645 ispart of Analog Device’s SoftCell™ transceiver chipset . TheAD6645 maintains 100 dB multitone, spurious-free dynamicrange (SFDR) through the second Nyquist band . This breakthrough performance eases the burden placed on multimodedigital receivers (software radios) that are typically limited bythe ADC . Noise performance is exceptional; typical signal-tonoise ratio is 74.5 dB through the first Nyquist band .

The AD6645 is built on Analog Devices’ high-speed complementary bipolar process (XFCB) and uses an innovative, multipasscircuit architecture . Units are available in a thermally enhanced 52-lead PowerQuad 4^® (LQFP_ED) specified from –40∞C to +85∞C .
