Datel ADS-939
The ADS-939 is a 16-bit, 10MHz sampling A/D converter. This device accurately samples full-scale input signals up to Nyquist frequencies with no missing codes. The dynamic performance of the ADS-939 has been optimized to achieve a signal-to-noise ratio (SNR) of 82dB and a total harmonic distortion (THD) of –86dB.| Part No. | ADS-939 |

GENERAL DESCRIPTION
Packaged in a 40-pin TDIP, the functionally complete ADS-939 contains a fast-settling sample-hold amplifier, a subranging (two-pass) A/D converter, an internal reference, timing/control logic, and error-correction circuitry. Digital input and output levels are TTL. The ADS-939 only requires the rising edge of the start convert pulse to operate. Requiring ±5V supplies and either ±12v or ±15V supplies the ADS-939 dissipates 3.0 Watts. The device is offered with a bipolar (±2.75V) or a unipolar (0 to –5.5V) analog input range. Models are available for use in either commercial (0 to +70°C) or military (–55 to +125°C) operating temperature ranges. A proprietary, auto-calibrating, error-correcting circuit enables the device to achieve specified performance over the full military temperature range.
