FEATURES
The AMC358 series is designed containing two
independent, high gain operational amplifiers. It can
operate from a single power supply over a wide range
from 4.5V to 30V.
Not only it can be used in all conventional
operation amplifiers circuits in single power
supply systems, the AMC358 series is also ideal
for transducer amplifiers, DC gain blocks and etc.
In addition, without the need of
±15V
dual power
supply voltages, the AMC358 series can be
directly operated from the 5V power supply
voltage which is also used for digital systems.
Large DC voltage gain (typical 100 dB)
Wide bandwidth (typical 1MHz)
Operated by either single supply or dual
supplies
High accuracy output voltage
Low input offset voltage (typical 2mV)
Large output voltage swing: 0V to
VCC – 1.5V
Low dropout voltage
Input common-mode voltage range includes
ground
Low supply current drain
Pin assignment identical to earlier LM358
series.

Short Circuit Output Current
(Note 6)
Note 2:
Note 3:
Note 4:
V
OUT
≅
1.4V, R
S
= 0Ω, with V
CC
from 4.5V to 30V; and over the full input common-mode range (0V to V
CC
– 1.5V)
at 25°C.
Due to PNP input stage, the direction of the input current is out of the IC. It is essentially constant, independent of the
state of the output, so no loading change exists on the input lines.
The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3V
(at 25°C). The upper limit of the common-mode voltage range is V
CC
– 1.5V (at 25°C), but either or both inputs can go to
32V without damage, independent of the magnitude of V
CC
.
These parameters, although guaranteed, are not tested in production.
Short Circuits from the output to V
CC
can cause excessive heating and eventual destruction. When considering short
circuits to ground, the maximum output current is approximately 40mA independent of the magnitude of V
CC
. At values
of supply voltage in excess of 15V, continuous short-circuit can exceed the power dissipation ratings and cause
destruction. Destructive dissipation can result from simultaneous shorts on all amplifiers.
