Low voltage operational amplifier
NE/SA5230
DESCRIPTION
The NE5230 is a very low voltage operational amplifier that can
perform with a voltage supply as low as 1.8V or as high as 15V. In
addition, split or single supplies can be used, and the output will
swing to ground when applying the latter. There is a bias adjusting
pin which controls the supply current required by the device and
thereby controls its power consumption. If the part is operated at
±0.9V
supply voltages, the current required is only 110µA when the
current control pin is left open. Even with this low power
consumption, the device obtains a typical unity gain bandwidth of
180kHz. When the bias adjusting pin is connected to the negative
supply, the unity gain bandwidth is typically 600kHz while the supply
current is increased to 600µA. In this mode, the part will supply full
power output beyond the audio range.
The NE5230 also has a unique input stage that allows the
common-mode input range to go above the positive and below the
negative supply voltages by 250mV. This provides for the largest
possible input voltages for low voltage applications. The part is also
internally-compensated to reduce external component count.
The NE5230 has a low input bias current of typically
±40nA,
and a
large open-loop gain of 125dB. These two specifications are
beneficial when using the device in transducer applications. The
large open-loop gain gives very accurate signal processing because
of the large “excess” loop gain in a closed-loop system.
The output stage is a class AB type that can swing to within 100mV
of the supply voltages for the largest dynamic range that is needed
in many applications. The NE5230 is ideal for portable audio
equipment and remote transducers because of its low power
consumption, unity gain bandwidth, and 30nV/√Hz noise
specification.

NOTES:
1. Can exceed the supply voltages when V

≤ ±7.5V
(15V).
2. The maximum operating junction temperature is 150°C. At elevated temperatures, devices must be derated according to the package ther-
mal resistance and device mounting conditions. Derate above 25°C at the following rates:
FE package at 6.7mW/°C
N package at 9.5mW/°C
D package at 6.25mW/°C
3. Momentary shorts to either supply are permitted in accordance to transient thermal impedance limitations determined by the package and
device mounting conditions.
