ha7-5137883 Intersil Corporation, ha7-5137883 Datasheet - Page 5

• Manufacturer Part Number: ha7-5137883
• Description: 63mhz, Ultra-low Noise Precision Operational Amplifier
• Manufacturer: Intersil Corporation

Application Information
NOTE: Tested Offset Adjustment Range is |V
NOTE: Low resistances are preferred for low noise applications as a 1k resistor has 4nV/ Hz of thermal noise. Total resistances of greater than
10k on either input can reduce stability. In most high resistance applications, a few picofarads of capacitance across the feedback resistor will
improve stability.
