A general purpose operational amplifier that allows the user to choose the
compensation capacitor best suited to his needs. With proper compensation,
summing amplifier slew rates to 10 V/µs can be obtained.
OPERATIONAL AMPLIFIERS
• Low Input Offset Current: 20 nA Maximum Over Temperature Range
• External Frequency Compensation for Flexibility
• Class AB Output Provides Excellent Linearity
• Output Short Circuit Protection
SEMICONDUCTOR
TECHNICAL DATA
• Guaranteed Drift Characteristics
