Mansfield, Mass.The ADS-939 sampling A/D converter from C&D Technologies is a fully integrated data acquisition system that provides 16-bit resolution at a 10-MHz sampling rate over the entire operating temperature range.
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 ADS-939 provides a high signal-to-noise (SNR) ratio of 82dB and total harmonic distortion (THD) of -86dB at Nyquist input frequency.
Specifications include a fast-setting sample-hold amplifier, a sub-ranging A/D converter, an internal reference, timing/control logic, and error-correction circuitry. Digital input and output levels are TTL.
Able to operate from a ±5V, ±12V or ±15V supply, the ADS-939 dissipates 1.5 Wattshalf the power consumption of the ADS-935 (16-bit, 5MHz) A/D converter.
The 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 (O°C to +70°C) and military (-55°C to +125°C) temperature ranges.
