ADC1241 Self-Calibrating 12-Bit Plus

Sign mP-Compatible AD Converter

with Sample-and-Hold

General Description

The ADC1241 is a CMOS 12-bit plus sign successive ap-

proximation analog-to-digital converter

On request

the

ADC1241 goes through a self-calibration cycle that adjusts

positive linearity and full-scale errors to less than g

LSB

each and zero error to less than g1 LSB The ADC1241

also has the ability to go through an Auto-Zero cycle that

corrects the zero error during every conversion

The analog input to the ADC1241 is tracked and held by the

internal circuitry and therefore does not require an external

sample-and-hold A unipolar analog input voltage range (0V

to a5V) or a bipolar range (b5V to a5V) can be accom-

modated with g5V supplies

The 13-bit word on the outputs of the ADC1241 gives a 2’s

complement representation of negative numbers The digi-

tal inputs and outputs are compatible with TTL or CMOS

logic levels
