Description
The Intersil ICL7106 and ICL7107 are high performance, low
power, 31/2 digit A/D converters. Included are seven seg-
ment decoders, display drivers, a reference, and a clock.
The ICL7106 is designed to interface with a liquid crystal dis-
play (LCD) and includes a multiplexed backplane drive; the
ICL7107 will directly drive an instrument size light emitting
diode (LED) display.
The ICL7106 and ICL7107 bring together a combination of
high accuracy, versatility, and true economy. It features auto-
zero to less than 10µV, zero drift of less than 1µV/oC, input
bias current of 10pA (Max), and rollover error of less than
one count. True differential inputs and reference are useful in
all systems, but give the designer an uncommon advantage
when measuring load cells, strain gauges and other bridge
type transducers. Finally, the true economy of single power
supply operation (ICL7106), enables a high performance
panel meter to be built with the addition of only 10 passive
components and a display.

Design Information Summary Sheet
• OSCILLATOR FREQUENCY
fOSC = 0.45/RC
COSC > 50pF; ROSC > 50kΩ
fOSC (Typ) = 48kHz
• OSCILLATOR PERIOD
tOSC = RC/0.45
• INTEGRATION CLOCK FREQUENCY
fCLOCK = fOSC/4
• INTEGRATION PERIOD
tINT = 1000 x (4/fOSC)
• 60/50Hz REJECTION CRITERION
tINT/t60Hz or tlNT/t60Hz = Integer
• OPTIMUM INTEGRATION CURRENT
IINT = 4µA
• FULL SCALE ANALOG INPUT VOLTAGE
VlNFS (Typ) = 200mV or 2V
• INTEGRATE RESISTOR
RINT = V----I-I-I-NN----F-T--S--
• INTEGRATE CAPACITOR
CINT = (---t--I--N---V-T---I-)-N-(--I-T-I--N----T----)
• INTEGRATOR OUTPUT VOLTAGE SWING
VINT
=
(---t--I--N----T----)--(--I--I--N----T----)
CINT
• VINT MAXIMUM SWING:
(V- + 0.5V) < VINT < (V+ - 0.5V), VINT (Typ) = 2V
• DISPLAY COUNT
COUNT = 1000 × V---V--R---I-EN----F-
• CONVERSION CYCLE
tCYC = tCL0CK x 4000
tCYC = tOSC x 16,000
when fOSC = 48kHz; tCYC = 333ms
• COMMON MODE INPUT VOLTAGE
(V- + 1V) < VlN < (V+ - 0.5V)
• AUTO-ZERO CAPACITOR
0.01µF < CAZ < 1µF
• REFERENCE CAPACITOR
0.1µF < CREF < 1µF
• VCOM
Biased between Vi and V-.
• VCOM ≅ V+ - 2.8V
Regulation lost when V+ to V- < ≅6.8V
If VCOM is externally pulled down to (V+ to V-)/2,
the VCOM circuit will turn off.
• ICL7106 POWER SUPPLY: SINGLE 9V
V+ - V- = 9V
Digital supply is generated internally
VGND ≅ V+ - 4.5V
• ICL7106 DISPLAY: LCD
Type: Direct drive with digital logic supply amplitude.
• ICL7107 POWER SUPPLY: DUAL ±5.0V
V+ = +5V to GND
V- = -5V to GND
Digital Logic and LED driver supply V+ to GND
• ICL7107 DISPLAY: LED
Type: Non-Multiplexed Common Anode
