MAX130

The MAX130 and MAX131 are 31/2 digit AID converters with onboard LCD display drivers. The MAX130 and MAX131 use a bandgap reference to generate an analog Common voltage which has the excellent long term stability of a bandgap reference and a guaranteed maximum temperature coefficient of 100ppm/°C. For more demanding applications the "A suffix" parts, the MAX130A and MAX131A, have a 50ppm/°C maximum temperature coefficient.

The MAX130 uses the same circuit and component values as the ICL7106, but draws a maximum supply current of only 250μA maximum (100μA typical) from a 9V battery, much lower than the 1800μA maximum supply current of the ICL7106. The MAX131 uses the same circuit and component values as the ICL7136, with a maximum supply current of 100μA (65μA typical).

These devices are available with both 0° C to 70° C and -40° C to +85° C operating temperature ranges. The operating voltage range is-from 4.5V to 14V.
