The ADSD-1420S is a functionally complete, dual 14 bit, 20MSPS, sampling A/D converter. Is standard, 40 pin triple-wide SMT package contain two fast settling sample/hold amplifiers, two 14 bit A/D converters, multiplexed output buffers, a precision reference, and all the timing and control logic necessary to operate from either two or a singlr start convert pulse. The ADSD-1420S is optimized for wideband frequency-domain applications and is fully FFT tested. The ADSD-1420S required only +/-5V supplies and typically consumed 1.6 watts. The digital output is capable of driving 5V or 3V logic systems. -55°C to +125°C operating temperature range.
