TC815

3-1/2 Digit Auto-Ranging A/D Converter with

Triplex LCD Drive and Display Hold Function

Features

General Description

• Auto-Range Operation for AC and DC Voltage

and Resistance Measurements

The TC815 is a 3-1/2 digit integrating analog-to-digital

converter with triplex LCD display drive and automatic

ranging. A display hold function is on-chip. Input volt-

age/ohm attenuators ranging from 1 to 1/10,000 are

automatically selected. Five full scale ranges are pro-

vided. The CMOS TC815 contains all the logic and

analog switches needed to manufacture an auto-

ranging instrument for ohms and voltage measure-

ments. User selected 20mA and 200mA current ranges

are available. Full scale range and decimal point LCD

annunciators are automatically set in auto-range oper-

ation. Auto-range operation is available during ohms

(high and low power ohms) and voltage (AC and DC)

measurements, eliminating expensive range switches

in hand-held DMM designs. The auto-range feature

may be bypassed allowing decimal point selection and

input attenuator selection control through a single line

input. Expensive rotary switches are not required.

- Two User Selected AC/DC Current Ranges

20mA and 200mA

• 22 Operating Ranges

- 9 DC/AC Voltage

- 4 AC/DC Current

- 9 Resistance and Low Power Ohms

• Display HOLD Function

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

- 1/2000

• Extended Resolution in Manual Mode: 1/3000

• Memory Mode for Relative Measurements:

- ±5% F.S.

• Internal AC to DC Conversion Op Amp

• Triplex LCD Drive for Decimal Points, Digits

and Annunciators

During Manual mode operation, resolution is extended

to 3000 counts full scale. The extended range opera-

tion is indicated by a flashing 1 MSD. The extended

resolution is also available during 200kΩ and 2000V

full scale auto-range operation.

• Continuity Detection and Piezoelectric

Transducer Driver

• Compact Surface Mounted 64-pin

Plastic Flat Package

The Memory mode subtracts a reading, up to ±5% of

full scale from subsequent measurements. Typical

applications involve probe resistance compensation for

resistance measurements, tolerance measurements,

and tare weight measurements.

• Low Drift Internal Reference: 75ppm/°C

• 9V Battery Operation: 10mW

• Low Battery Detection and LCD Annunciator

Device Selection Table

The TC815 includes an AC to DC converter for

AC measurements. Only external diodes/resistors/

capacitors are required.

Temperature Range

Part Number

Package

A complete LCD annunciator set describes the TC815

meter function and measurement range during ohms,

voltage and current operation. AC measurements are

indicated as well as auto-range operation. A low battery

detection circuit also sets the low battery display

annunciator. The triplex LCD display drive levels may

be set and temperature compensation applied via the

TC815CBU

64-Pin PQFP

0°C to +70°C

pin. With HOLD low, the display is not updated.

DISP

A HOLD mode LCD annunciator is activated.

The “low ohms” measurement option allows in-circuit

resistance measurements by preventing semiconduc-

tor junctions from being forward biased.
