High Output Current
Low Power, Low Noise Bipolar
Operational Amplifiers
employing Bipolar technology with innovative high performance concepts for
quality audio and data signal processing applications. This device family
incorporates the use of high frequency PNP input transistors to produce
amplifiers exhibiting low input offset voltage, noise and distortion. In addition,
the amplifier provides high output current drive capability while consuming
only 420 A of drain current per amplifier. The NPN output stage used,
exhibits no deadband crossover distortion, large output voltage swing,
excellent phase and gain margins, low open–loop high frequency output
impedance, symmetrical source and sink AC frequency performance.
tested over the vehicular temperature range, and are available in DIP and
SOIC packages.
