GENERAL DESCRIPTION
The low-cost ADS-937 is a 16-bit, 1MHz sampling A/D converter. This device
accurately samples full-scale input signals up to Nyquist frequencies with no
missing codes. This feature, combined with excellent signal-to-noise ratio
(SNR) and total harmonic distortion (THD), makes the ADS-937 the ideal choice
for both time-domain (CCD/medical imaging, scanners, process control) and
frequency-domain (radar, telecommunications, spectrum analysis) applications.
Packaged in a 32-pin, side-brazed, metal-sealed, ceramic TDIP, the functionally
complete ADS-937 contains a fastsettling 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-937 only
requires the rising edge of the start convert pulse to operate.
Requiring ±15V and ±5V supplies, the ADS-937 typically dissipates 1.25 Watts.
The device is offered with both bipolar (±5V) and unipolar (0 to –10V) analog
input ranges. 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.
