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.

DATEL, Inc. is a leading supplier of High Precision Data Acquisition Components and DC to DC converters. Our leadership status in high-performance data acquisition components is unchallenged, driven in large part by our engineering expertise to develop solutions with outstanding electrical performance, small packaging, low power consumption and ease of use. These products employ five basic technologies: monolithic IC, thin-film hybrid, thick-film hybrid, SMT technologies and discrete component circuit.

DATEL's DC DC converter product line includes non-isolated point-of-loads dc/dc, switching regulators as well as a complete line of industry standard brick packages (Sixteenth-Brick, Eighth-Brick, Quarter-Brick, Half-Brick and Full-Brick) and railway dc-dc converters.
