LM1815EP
OBSOLETE
July 23, 2010
Enhanced Plastic Adaptive Variable Reluctance Sensor
Amplifier
General Description
The LM1815EP is an adaptive sense amplifier and default
gating circuit for motor control applications. The sense am-
plifier provides a one-shot pulse output whose leading edge
coincides with the negative-going zero crossing of a ground
referenced input signal such as from a variable reluctance
magnetic pick-up coil.
In normal operation, this timing reference signal is processed
(delayed) externally and returned to the LM1815EP. A Logic
input is then able to select either the timing reference or the
processed signal for transmission to the output driver stage.
The adaptive sense amplifier operates with a positive-going
threshold which is derived by peak detecting the incoming
signal and dividing this down. Thus the input hysteresis varies
with input signal amplitude. This enables the circuit to sense
in situations where the high speed noise is greater than the
low speed signal amplitude. Minimum input signal is
150mV
P-P.
