FEATURES

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.
