TC818A

Auto-Ranging Analog-to-Digital Converter

with 3-1/2 Digit Display

Features

General Description

• Auto-Ranging Analog-to-Digital Converter with

3-1/2 Digit Display

The TC818A is an integrating analog-to-digital con-

verter (ADC) with a 3-1/2 digit numeric LCD driver,

automatic ranging, and single 9V battery operation.

The numeric display provides 0.05% resolution and a

full set of annunciators that spell out the TC818A's

many operating modes.

• Annunciator Outputs Permit Customizing of LCD

• Auto-Range Operation for AC and DC Voltage

and Resistance Measurements

• Two User Selected AC/DC

• Current Ranges: 20mA and 200mA

• 22 Operating Ranges: 9 DC/AC Voltage

• 4 AC/DC Current

Automatic range selection is provided for both voltage

(DC and AC) and ohms (high and low power) measure-

ments. Expensive and bulky mechanical range

switches are not required. Five full scale ranges are

available, with automatic selection of external volt/ohm

attenuators over a 1 to 10,000 range. Two current

ranges, 20mA and 200mA, can be manually selected.

The auto-range feature can be bypassed, allowing

input attenuator selection through a single line input.

• 9 Resistance and Low Power Ohms

• Display Hold Function

• 3-1/2 Digit Resolution in Auto-Range

Mode: 1/2000

• Extended Resolution in Manual Range

Mode: 1/3000

During Manual mode operation, resolution is extended

to 3000 counts full scale. Extended resolution is also

available during 2000kΩ and 2000V full scale auto-

range operation. The extended range operation is indi-

cated by a flashing 1 MSD and by the fully extended bar

graph.

• Internal AC-to-DC Conversion Op Amp

• Triplex LCD Drive for Decimal Points, Digits,

• Bar Graphs, and Annunciators

• Continuity Detection and Piezoelectric

Transducer Driver

The TC818A includes an AC-to-DC converter for AC

voltage and current measurements. Only external

diodes/resistors/capacitors are required. Other fea-

tures include a Memory mode, low battery detection,

display HOLD input, and continuity buzzer driver.

• Low Drift Internal Reference: 75ppm/°C

• 9V Battery Operation: 10mW

• Low Battery Detection and LCD Annunciator

Device Selection Table

The 3-1/2 digit numeric display includes a full set of

annunciators. Decimal points are adjusted as auto-

matic or manual range changes occur, and Voltage,

Current, and Ohms Operating modes are displayed.

Additional annunciators are activated for manual, auto,

memory, HOLD, AC, low power ohms, and low battery

conditions.

0°C to +70°C

The TC818A is available in a surface mounted 64-pin

flat package. Combining a numeric display driver, sin-

gle 9V battery operation, internal range switching, and

compact surface mounting, the TC818A is ideal for

advanced portable instruments.
