HA7-5127-5 INTERSIL [Intersil Corporation], HA7-5127-5 Datasheet - Page 5

• Manufacturer Part Number: HA7-5127-5
• Description: 8.5MHz, Ultra-Low Noise Precision Operational Amplifier
• Manufacturer: INTERSIL [Intersil Corporation]

Application Information
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.
