Application Notes
a) General information
The output pins Q
+
and Q
-
must be terminated equally to prevent instabilities.
It is recommended to minimize stray capacitance when connecting photodiode to
transimpedance amplifier.
To improve power supply rejection ratio (
PSRR
),
V
CC
should be supplied via resistor
(4.7
), capacitor (100 nF) to GND, and inductor (BLM11A601, Murata) to
V
CC
-pin.
The monitor pin (not used in these application notes) must be left open or connected
to
V
CC
via resistor of 0 … 2 k
.
