ES5120
3 3/4 DIGIT A/D CONVERTER
Two logic level measurement inputs permit a ES5120-based
meter to function as a logic probe. When combined with external
level shifters, the ES5120 will display logic levels on the LCD
display and also turn on a piezoelectric buzzer when the measured
logic level is low.
Other ES5120 features simplify instrument design and reduce
parts count. On-chip decimal point drivers are included, as is a
low battery detection annunciator. A piezoelectric buzzer can be
controlled with an external switch or by the logic probe inputs.
Two oscillator options are provided : A crystal can be used if
high accuracy frequency measurements are desired, or a simple RC
option can be used for low-end instruments.
A 'peak reading hold' input allows the ES5120 to retain
the highest A-D or frequency reading. This feature is useful in
measuring motor starting current, maximum temperature, and
similar applications.
The ES5120 operates from a single 9V battery, with typical
power of 16mW. Packages include a 40-pin DIP and 44-pin Flat
Package.
