Dual 14-Bit A/D converters provide 20 MSPS conversions for commercial, military applications

Mansfield, Mass. — C&D Technologies has added the ADSD-1420S and ADSD-1420S-EX to its range of dual, sampling A/D converters. The 14-bit resolution modules provide a 20 megasamples per second (MSPS) sampling rate with no missing codes over their full temperature range. The ADSD-1420S is designed for commercial applications and has an operating temperature range of 0°C to +70°C. The ADSD-1420EX has an operating temperature range of -55°C to +125°C, suitable for industrial or military applications.

The modules have a 2.5 V input range and are suited to both time and wideband frequency-domain applications. They offer signal-to-noise ratio performance of 75 dB, plus total harmonic distortion of -80 dB. Typical applications include high-speed data acquisition systems, medical instruments, radar I/Q, DSP, and automatic test equipment (ATE) for military, industrial or commercial applications.

Housed in an industry standard 40-pin, triple-wide, SMT DIP, the ADSD-1420S and ADSD-1420S-EX contain two sample/hold amplifiers, two 14-bit A/D converters, multiplexed output buffers, a precision reference, and the ability to operate from either one or two single start convert pulses. The reference can be “daisy-chained” to allow multiple modules to be used together to create larger A/D systems. The modules are FFT tested, and require 5 V supply while consuming 1.6 W typical. The separate digital voltage pin can be set to 5 V or 3 V to allow compatibility with systems using either logic level.
