GENERAL DESCRIPTION
DATEL's ADS-941 is a functionally complete, 14-bit, 1MHz,
sampling A/D converter. Its standard, 32-pin, triple-wide
ceramic DIP contains a fast-settling sample/hold amplifier, a
14-bit subranging (two-pass) A/D converter, a precision
reference, a three-state output register, and all the timing and
control logic necessary to operate from a single start convert
pulse.
The ADS-941 is optimized for wideband frequency-domain
applications and is fully FFT tested. Total harmonic distortion
(THD) and signal-to-noise ratio (including distortion) typically
run at –85dB and 80dB, respectively, with full-scale inputs up
to 100kHz.
The ADS-941 requires ±15V and +5V supplies and typically
consumes 2.8 Watts.
