Savitech SV7321, SV7358, SV7324 SV7321, SV7358, SV7324 www.savitech-ic.com Low Power, Low Noise, 1.2MHz, Rail-to-Rail Input/Output, General Purpose CMOS Operational Amplifiers

Features

■ Wide power supply range: +2.1V to +5.5V ■ Gain-bandwidth product, GBP (typ.) = 1.2MHz ■ Low Noise Voltage Density: 20nV/√Hz ■ Very low quiescent current per amplifier: 60µA ■ Low input bias current: 1pA ■ Low Offset: V OS (typ.) = 1mV, IOS (typ.) = 1pA ■ Unity Gain Stable Pin Connection

Description

The SV7321, SV7358 and SV7324 consist of 1/2/4 independent, low power, low noise, internally frequenc y- compensated CMOS operational amplifiers. It also features wider bandwidth, lower quiescent and lower offset than legacy LMV operational amplifier family. They operate from a single power supply ranging from +2.1V to +5.5V. 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.

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.
