Convertors satisfy current-hungry applications
Isolated wide-input-range DC/DC convertors deliver 50-60W of power from a standard 40.6 x 50.8 x 10.16mm PCB-mounting open-frame package.
Eighth-brick convertors power up to 100W
Murata Power Solutions has a new series of cost-effective eighth-brick DC/DC convertors.
Typical applications include medical imaging, radar, sonar, communications and instrumentation.
The rising edge triggered ADS-939 is ideal for use in both time and frequency domain applications.
It accurately samples full-scale input signals with no missing codes up to Nyquist frequencies and across the full operating temperature range.
The dynamic performance of the new device has been optimised to give a high signal-to-noise (SNR) ratio of 82dB and total harmonic distortion (THD) of -86dB at Nyquist input frequency.
The specification of the ADS-939 includes a fast-setting sample-hold amplifier, a sub-ranging A/D convertor, an internal reference, timing/control logic, and error-correction circuitry.
Digital input and output levels are TTL.
Able to operate from a +/-5, +/-12 or +/-15V supply, the ADS-939 dissipates just 1.5W - half the power consumption of the ADS-935 (16-bit, 5MHz) A/D convertor for which it is a pin-for-pin replacement.
The new device is offered with a bipolar (+/-2.75V) or a unipolar (0 to -5.5V) analogue input range.
Variants are available to address applications with both commercial (0 to 70C) and military (-55 to +125C) temperature ranges. Request a free brochure from Murata Power Solutions ...
