FEATURES
GENERAL DESCRIPTION
The ADS-926 is a high-performance, 14-bit, 500kHz sampling
A/D converter. This device accurately samples full-scale input
signals up to Nyquist frequencies with no missing codes and
exhibits outstanding dynamic performance that surpasses
most 16-bit, 500kHz sampling A/D's. THD and SNR, for
example, are typically –90dB and 80dB when converting full-
scale input signals up to 100kHz.
Housed in a small 24-pin DDIP or SMT (gull-wing) package,
the functionally complete ADS-926 contains a fast-settling
sample-hold amplifier, a subranging (two-pass) A/D converter,
a precise voltage reference, timing/control logic, and error-
correction circuitry. Digital input and output levels are TTL.
Requiring ±15V (or ±12V) and +5V supplies, the ADS-926
dissipates only 1.75W (1.6W for ±12V), maximum. The unit is
offered with a bipolar input (–5V to +5V). Models are available
for use in either commercial (0 to +70°C) or military (–55 to
+125°C) operating temperature ranges.
Applications include radar, sonar, spectrum analysis, and
graphic/medical imaging. Contact DATEL for information on
devices screened to MIL-STD-883.
