TC820

3-3/4 Digit A/D Converter with Frequency Counter

and Logic Probe

Features

General Description

• Multiple Analog Measurement System

- Digit A/D Converter

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 fre-

quency 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 (bat-

tery) and features a built-in battery low flag. Function

and decimal point selection are accomplished with sim-

ple logic inputs designed for direct connection to an

external microcontroller or rotary switch.

- 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:

Two LCD Annunciators

Buzzer Driver

• 3-3/4 Digit Display with Over Range Indicator

• LCD Display Driver with Built-in Contrast Control

• Data Hold Input for Comparison Measurements

• Low Battery Detect with LCD Annunciator

• Under Range and Over Range Outputs

• On-Chip Buzzer Driver with Control Input

• 40-Pin Plastic DIP, 44-Pin Plastic Flat Pack, or

44-Pin PLCC Packages
