µPC4071
J-FET INPUT LOW-NOISE OPERATIONAL AMPLIFIER
DESCRIPTION The µPC4071 is a J-FET input operational amplifier. This product is designed as low noise version of the µPC4081. The Features of the µPC4071 are more improved input equivalent noise voltage, input offset voltage and input bias current than those of µPC4081. By these Features
, the µPC4071 is excellent choice for wide variety of applications including audio preamplifier and active filter.
Features
- Low noise: en = 18 nV/ Hz (TYP.)
- Very low input bias and offset currents
- Output short circuit protection
- High input impedance...J-FET Input stage
- Internal frequency pensation
- High slew rate...13 V/µs (TYP.)
