The TC7136 and TC7136A are low-power,3-1/2 digit with liquid crystal display (LCD)drivers with analog-to-digital converters.These devices incorporate an \"integrator output zero\"phase which guarantees overrange recovery.The performance of existing TC7126,TC7126A and ICL7126-based systems may be upgraded with minor changes to external,passive components. The TC7136A has an improved internal zener reference voltage circuit which maintains the analog common temperature drift to 35ppm/°C (typical)and 75 ppm/°C (maximum).This represents an improvement of two to four times over similar 3-1/2 digit converters.The costly,space-consuming external reference source may be removed. The TC7136/A limits linearity error to less than 1 count on 200mV or 2V full-scale ranges.Roll-over error — the difference in readings for equal magnitude but opposite polarity input signals — is below ±1 count. High-impedance differential inputs offer 1 pA leakage currents and a 10 12 ? input impedance.The differential reference input allows ratiometric measurements for ohms or bridge transducer measurements.The 15 μVP-P noise performance guarantees a \"rock solid\" reading.The auto-zero cycle guarantees a zero display readout for a 0V input.
