ADC1251 Self-Calibrating 12-Bit Plus Sign

A/D Converter with Sample-and-Hold

8-bit mP/DSP interface

General Description

Bipolar input range with a single 5V reference

No missing codes over temperature

The ADC1251 is a CMOS 12-bit plus sign successive ap-

proximation 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 cor-

rects the zero error during every conversion.

TTL/MOS input/output compatible

Conversion Time

The analog input to the ADC1251 is tracked and held by the

internal circuitry, so an external sample-and-hold is not re-

quired. The ADC1251 has an S/H control input which direct-

ly controls the track-and-hold state of the A/D. A unipolar

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.
