LME49725
www.ti.com SNAS427A –APRIL 2008–REVISED APRIL 2013
APPLICATION INFORMATION
OPERATING RATINGS AND BASIC DESIGN GUIDELINES
The LME49725 has a supply voltage range from +9V to +36V single supply or ±4.5V to ±18V dual supply.
Bypass capacitors for the supplies should be placed as close to the amplifier as possible. This will help minimize
any inductance between the power supply and the supply pins. In addition to a 10μF capacitor, a 0.1μF capacitor
is also recommended.
The amplifier’s inputs lead lengths should also be as short as possible. If the op amp does not have a bypass
capacitor, it may oscillate.
