AMPLIFIER IC FOR SENSORS WITH DIFFERENT CONDUCTANCE
Functional Description
Designed IC is an integrated circuit (IC) of the
amplifier for sensors with different conductance.
IL1815 – is an IC of adaptive amplifier
increasing analog signal from the sensor and
transmitting a strobe of pulses from IC output
into electrical circuit of motor engine control
device. The amplifier ensures one short output
pulse leading edge of which coincides with
negative half-wave, crossing zero of input
analog signal produced by alternating magnetic
field of inductive sensor coil.
TA = –40 ÷ +125°С
Functions
IC is purposed for application in automotive electronics in injection controller block as
well as in engine control system for:
crankshaft position (condition) control;
Switching when crossing zero;
engine rotation speed control;
tachometer (rotation speed measurement);
engine check (testing).
IC IL1815 is analog to microcircuit of the third integration scale and comprises 131 elements.
The circuit is implemented in 14-pin DIP-package of MS-001AA (IL1815N) type and in 14-pin SO-
package of MS-012AB (IL1815D) type.
Connection of loading of 1 kOhm to IC output (to pin 10) is tolerable.
Features
Adaptive hysteresis
One-polar power supply mode
Influence of «ground» on input
Precise choice of the initial ignition moment
Operation in the supply voltage range of 2,5 V up to 12 V
control of input (pin 3) by signal coming into external resistor with amplitude from 75 mV up to
120V.
Compatibility with CMOS - logic
