Design Information Summary Sheet
V IN
R INT = -----------------
C INT = --------------------------------
C INT
? OSCILLATOR FREQUENCY
f OSC = 0.45/RC
C OSC > 50pF; R OSC > 50k ?
f OSC (Typ) = 48kHz
? OSCILLATOR PERIOD
t OSC = RC/0.45
? INTEGRATION CLOCK FREQUENCY
f CLOCK = f OSC /4
? INTEGRATION PERIOD
t INT = 1000 x (4/f OSC )
? 60/50Hz REJECTION CRITERION
t INT /t 60Hz or t lNT /t 60Hz = Integer
? OPTIMUM INTEGRATION CURRENT
I INT = 4 μ A
? FULL SCALE ANALOG INPUT VOLTAGE
V lNFS (Typ) = 200mV or 2V
? INTEGRATE RESISTOR
V INFS
I INT
? INTEGRATE CAPACITOR
( t INT ) ( I INT )
V INT
? INTEGRATOR OUTPUT VOLTAGE SWING
( t INT ) ( I INT )
V INT = --------------------------------
? V INT MAXIMUM SWING:
(V- + 0.5V) < V INT < (V+ - 0.5V), V INT (Typ) = 2V
? DISPLAY COUNT
COUNT = 1000 × ---------------
V REF
? CONVERSION CYCLE
t CYC = t CL0CK x 4000
t CYC = t OSC x 16,000
when f OSC = 48kHz; t CYC = 333ms
? COMMON MODE INPUT VOLTAGE
(V- + 1V) < V lN < (V+ - 0.5V)
? AUTO-ZERO CAPACITOR
0.01 μ F < C AZ < 1 μ F
? REFERENCE CAPACITOR
0.1 μ F < C REF < 1 μ F
? V COM
Biased between Vi and V-.
? V COM ? V+ - 2.8V
Regulation lost when V+ to V- < ? 6.8V
If V COM is externally pulled down to (V+ to V-)/2,
the V COM circuit will turn off.
? ICL7106 POWER SUPPLY: SINGLE 9V
V+ - V- = 9V
Digital supply is generated internally
V GND ? 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
Typical Integrator Amplifier Output Waveform (INT Pin)
AUTO ZERO PHASE
