TC7136ACPL General Description

The TC7136 and TC7136A are low-power, 3-1/2 digit with liquid crystal display (LCD) drivers with analog-todigital 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 35 ppm/°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, spaceconsuming external reference source may be removed.

*Static-sensitive device. Unused devices must be stored in conductive material. Protect devices from static 
discharge and static fields. Stressesabove those listed under Absolute Maximum Ratings may cause 
permanent damage to the device. These are stress ratings only and functionaloperation of the device at
 these or any other conditions above those indicated in the operational sections of the specifications is not implied.
Exposure to Absolute Maximum Rating Conditions for extended periods may affect device reliability.
