Product Summary

The AD6645ASQZ-80 is a high-speed, high-performance, monolithic 14-bit analog-to-digital converter. All necessary functions, including track-and-hold (T/H) and reference, are included on the chip to provide a complete conversion solution. The AD6645ASQZ-80 provides CMOS-compatible digital outputs. It is the fourth generation in a wideband ADC family, preceded by the AD9042 (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 AD6645ASQZ-80 is part of Analog Device SoftCell. transceiver chipset. The AD6645ASQZ-80 maintains 100 dB multitone, spurious-free dynamic range (SFDR) through the second Nyquist band. This breakthrough performance eases the burden placed on multimode digital receivers (software radios) that are typically limited by the ADC. Noise performance is exceptional; typical signal-tonoise ratio is 74.5 dB through the first Nyquist band.
