UPC4570
UPC4570 is DUAL OPERATIONAL AMPLIFIER manufactured by NEC.
DESCRIPTION
The µPC4570 is an ultra low-noise, wideband high slew-rate, dual operational amplifier. Input equivalent noise is three times better than the conventional 4558 type op-amps. The gain bandwidth products and the slew-rate are seven times better than 4558. In spite of fast AC performance, the µPC4570 is extremely stable under voltage-follower circuit conditions. Supply current is also improved pared with conventional wideband op-amps. The µPC4570 is an excellent choice for pre-amplifiers and active filters in audio, instrumentation, and munication circuits.
FEATURES
- Ultra low noise : en = 4.5 n V/√Hz
- High slew rate : 7 V/µs
- High gain bandwidth product : GBW = 15 MHz at 100 k Hz
- Internal frequency pensation
