LED-display digital panel meters answer growing market requirement for displays that can be used in very high ambient light conditions, but can also dim themselves in poorer light
C and D Technologies has added the ADSD-1420S and ADSD-1420EX to its range of dual sampling A/D convertors. The functionally complete 14bit resolution modules provide a 20Msample/s sampling rate and no missing codes over their full temperature range. The ADSD-1420S is designed for commercial applications and has an operating temperature range of 0 to +70C.
The ADSD-1420EX has an operating temperature range of -55 to +125C, suitable for more demanding industrial or military applications.
The new edge triggered modules have a +/-2.5V input range and are suited to both time and wideband frequency-domain applications.
They offer signal-to-noise ratio performance of 75dB, plus total harmonic distortion of -80dB making them ideal for designs with low-noise requirements.

Shelf saves designers from custom power chassis
Powershelf is designed to accommodate up to three D1U AC/DC front-end power supplies in parallel
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-1420EX contain: two fast-settling sample/hold amplifiers; two 14bit A/D convertors; multiplexed output buffers; a precision reference; and all the timing and control logic necessary to operate from either one or two single start convert pulses.
The new modules are fully FFT tested, and require only a +/-5V supply while consuming just 1.6W typical.
Their digital output power supply is capable of directly driving either 5 or 3V logic systems.
