AD6645ASQ-105

The AD6645ASQ-105 is an analog-to-digital converter designed for high-speed data acquisition applications. It provides a resolution of 14 bits and supports sampling rates up to 105 MSPS. The device offers a typical signal-to-noise ratio of 75 dB and a spurious-free dynamic range of 89 dBc at 70 MHz input frequency. Its differential input voltage range is 2 to 2.4 V p-p, with a differential input resistance of 250 kΩ and input capacitance of 1.5 pF. The converter operates over a temperature range of -40°C to +85°C at 80 MSPS and -10°C to +85°C at 105 MSPS. It is packaged in a 52-lead PowerQuad LQFP case and is surface mount. The device features a power dissipation of approximately 1.5 W and supports a digital output format of twos complement compatible with 3.3 V CMOS logic.
