► Low Noise
Low Noise Precision Op Amps
It is critical to have an amplifier having very low
background noise when the desired signal is weak or
absent. Intersil’s high voltage low noise op amps are
developed on dielectrically isolated PR40 to offer low
noise and improved THD.
Key Specifications
• Low Frequency Noise (0.1 to 10Hz)
• Wideband Voltage Noise (@ 1kHz)
• Wideband Current Noise (@ 1kHz)
• THD+N (in dB or %)
