General Description Features The consists of two low noise, high performance operational amplifiers. It is specially suitable for applications in differential-in, differential-out as well as in industrial measurement tools and applications where gain and phase matched channels are mandatory. The IC features monolithic silicon chip, internal frequency compensation, low noise, low distortion, wide operating voltage range, high gain and high bandwidth. The can operate under dual power supply voltage up to ±18V or single power supply up to 36V. Operating voltage: ±2V ~ ±18V Large DC voltage gain: 110 db Low input noise voltage: 1µV RMS Wide gain bandwidth product: 7 MHz Slew rate: 3V/µs Package outline: DIP8, SOIC8 Applications Audio AC-3 decoded system Audio amplifier AC/DC converter SOIC-8 DIP-8 Figure 1.
