Datel ADSD-1402S
ADSD-1402S is a functionally complete, dual 14- bit, 2MSPS, 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. The ADSD-1402S is optimized for wideband frequencydomain applications and is fully FFT tested.| Part No. | ADSD-1402S |
