MILITARY DATA SHEET
SELF-CALIBRATING 12-BIT PLUS SIGN A/D CONVERTER WITH
SAMPLE-AND-HOLD
General Description
The ADC1251 is a CMOS 12-bit plus sign successive approximation analog-to-digital
converter. On request, the ADC1251 goes through a self-calibration cycle that adjusts for
any zero, full scale, or linearity errors. The ADC1251 also has the ability to go through
an Auto-Zero cycle that corrects the zero error during every conversion.
The analog input to the ADC1251 is tracked and held by the internal circuitry, so an
external sample-and-hold is not required. The ADC1251 has an S/H control input which
directly controls the track-and-hold state of the A/D. A unipolar analog input voltage
range (0 to +5V) or a bipolar range (-5V to +5V) can be accommodated with +5V supplies.
The 13-bit data result is available on the eight outputs of the ADC1251 in two bytes,
high-byte first and sign extended. The digital inputs and outputs are compatible with TTL
or CMOS logic levels.
