Micro Power, Low Noise Operational Amplifiers
Description
The SV8541A/SV8542A/SV8544A consist of 1/2/4
Features
Wide power supply range: +1.8 V to +5.5V
Very low quiescent current per amplifier: 25 µA
Low Noise: eN = 17nV/ꢀHz
independent, high gain, internally frequency-
compensated operational amplifiers. They operate
from a single power supply ranging from +1.8V to
+5.5V and consume very low current that make them
idea for two to four battery powered applications.
Operation from split power supplies is also possible
and the low power supply current drain is
independent of the magnitude of the power supply
voltage. The family also features low noise, low
output offset voltage, low input offset current and low
input bias current that make the family idea for
sensor application within noisy environment
Gain bandwidth product, GBP(typ)= 1.2 MHz
Low drift: VOS (typ) = 0.6mV, IOS (typ)= 0.5pA
Low input bias current: IB (typ) = 0.5pA
Unity Gain Stable
Excellent Radio Frequency Immunity
(Pass IEC 1000-4-3 Radiated Immunity Class 2)

NOTE: Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a
stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.
CAUTION
This integrated circuit can be damaged by ESD if you don’t pay attention to ESD protection. SAVITECH recommends that
all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation
procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure.
Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the
device not to meet its published specifications.
