Datel ADSD-1420S
The ADSD-1420S is a functionally complete, dual 14-bit, 20MSPS, sampling A/D converter. Its standard, 40-pin, triple-wide SMT DIP contains 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 single start convert pulse. 34 EOC A 33 ANALOG GROUND 32 –5V 31 ENABLE B The ADSD-1420S is optimized for wideband frequency-domain applications and is fully FFT tested.| Part No. | ADSD-1420S |
