FEATURES
GENERAL DESCRIPTION
The ADSD-1420S is a functionally complete, dual
14-bit, 20MSPS, sampling A/D converter. Its standard,
40-pin, triple-wide SMT DIP contains two fast-settling
sample/hold amplifiers, two 14-bit A/D converters,
multiplexed output buffers, a precision reference, and
all the timing and control logic necessary to operate
from either two or a single start convert pulse.
The ADSD-1420S is optimized for wideband
frequency-domain applications and is fully FFT tested.
The ADSD-1420S requires only ±5V supplies and
typically consumes 1.6 Watts. The digital output power
supply is capable of directly driving 5V or 3V logic
systems. Models are available in either commercial
0 to +70°C or military -55 to +125°C operating
temperature ranges.
