TC7136 General Description
The TC7136 and TC7136A are low power, 3-1/2 digit with liquid crystal display (LCD) drivers and analog-todigital
converters. These devices incorporate an "integrator output zero" phase, which enables over range recovery. The performance of existing TC7126, TC7126A and ICL7126 based systems may be upgraded with minor changes to external, passivecomponents.
The TC7136A has an improved internal zener reference voltage circuit which maintains the analog common temperature drift to 35ppm/°C (typical) and 75ppm/°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.
