ADSD-1420S and ADSD-1420S-EX are the latest additions to C&D Technologies range of dual sampling A/D converters. Functionally complete 14-bit resolution modules provide a 20 mega samples per second (MSPS) sampling rate with no missing codes over the full temperature range. ADSD-1420S has an operating range of 0 to 70 °C. ADSD01420EX has an operating range of -55 to 125 °C. Edge-triggered modules have a ±2.5 V input range and are suited to time and wideband frequency-domain applications. They offer a signal-to-noise ratio performance of 75 dB and a total harmonic distortion of -80 dB. Typical applications include high-speed DAQ, radar I/Q, digital signal processing, and automatic test equipment. They are housed in an industry standard, 40-pin, triple-wide, SMT DIP and contain two fast-settling sample/hold amplifiers; two 14-bit A/D converters; multiplexed output buffers; a precision reference; and the timing and control logic necessary to operate from one or two single-start convert pulses. Multiple modules can be daisy-chained and used together to create larger A/D systems. www.cd4power.com
