ADC1251 Self-Calibrating 12-Bit Plus Sign

AD Converter with Sample-and-Hold

General Description

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

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 AD A unipolar

analog input voltage range (0 to a5V) or a bipolar range

(b5V to a5V) can be accommodated with g5V 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
