The LTC
1541/LTC1542 combine a micropower ampli-
fier, comparator and bandgap reference (LTC1541) in an
8-pin package. The part operates from a single 2.5V to
12.6V or dual
±
1.25V to
±
6.3V supply with a typical supply
current of 5
μ
A. Both the op amp and comparator feature
a common mode input voltage range that extends from the
negative supply to within 1.3V of the positive supply. The
op amp output stage swings from rail-to-rail. The
comparator’s inverting input is internally connected to the
reference output (LTC1541).
The reference output voltage is 1.2V
±
1% over the
extended temperature range. The output can drive a
bypass capacitor of up to 0.01
μ
F without any oscillations.
It can also source up to 2mA and sink up to 20
μ
A.
The op amp is internally compensated to be unity-gain
stable with typical GBW at 12kHz and slew rate of 8V/ms.
The comparator has
±
3mV of internal hysteresis to ensure
clean output switching, even with slow moving input
signals.
The LTC1541/LTC1542 are available in MSOP and SO-8
packages.
