DATEL The ADS-939 sampling A/D converter is a fully integrated data acquisition system that gives true 16-bit resolution performance at a 10MHz sampling rate over the entire operating temperature range, up to full Military. The functionally complete design requires no external components and is housed in a small, high reliability, hermetically sealed, 40-pin ceramic TDIP.

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 optimized to give a high signal-to-noise (SNR) ratio of 82dB and total harmonic distortion (THD) of -86dB at Nyquist input frequency.

Able to operate from a ±5V, ±12V or ±15V supply, the ADS-939 dissipates just 1.5 Watts - half the power consumption of the ADS-935 (16-bit, 5MHz) A/D converter for which it is a pin-for-pin replacement. The new device is offered with a bipolar (±2.75V) or a unipolar (0V to -5.5V) analog input range.

Variants are available to address applications with both commercial (OºC to +70ºC) and military (-55ºC to +125ºC) temperature ranges.
