TC820  
3-3/4 DIGIT A/D CONVERTER WITH FREQUENCY  
COUNTER AND LOGIC PROBE  
GENERAL DESCRIPTION  
FEATURES  
■ Multiple Analog Measurement System  
— Digit A/D Converter  
— Frequency Counter  
— Logic Probe  
■ Low Noise A/D Converter:  
— Differential Inputs, (1pA Bias Current)  
— On-Chip 50PPM/°C Voltage Reference  
■ Frequency Counter:  
— 4Mhz Maximum Input Frequency  
— Auto-ranging Over Four Decade Range  
■ Logic Probe:  
The TC820 is a 3-3/4 digit, multi-measurement system  
especially suited for use in portable instruments. It inte-  
grates a dual slope A/D converter, auto-ranging frequency  
counter and logic probe into a single 44-pin surface mount  
or 40-pin through hole package. The TC820 operates from  
a single 9V input voltage (battery) and features a built-in  
battery low flag. Function and decimal point selection are  
accomplished with simple logic inputs designed for direct  
connection to an external microcontroller or rotary switch.  
Ease of use, low power operation and high functional  
integration make the TC820 desirable in a variety of analog  
measurement applications.  
— Two LCD Annunciators  
— Buzzer Driver  
■ 3-3/4 Digit Display with Overrange Indicator  
■ LCD Display Driver with Built-in Contrast Control  
■ Data Hold Input for Comparison Measurements  
■ Low Battery Detect with LCD Annunciator  
■ Underrange and Overrange Outputs  
■ On-Chip Buzzer Driver with Control Input  
■ 44-Pin Plastic Flat Pack or PLCC or 40-Pin Plastic
