μPC4570

Ultra Low-Noise, High Speed, Wide Band,

Dual Operational Amplifier

DESCRIPTION

μPC4570 is a high performance version of general-purpose low-noise operational amplifier μPC258, 4558.

Various characteristics such as band, slew rate, including input equivalent noise were greatly improve in

comparison to μPC258 and 4558. It is also possible to operate the amplifier with stability for gain of 1 (total

feedback or unity gain)

Therefore, it is ideal for application circuits such as audio preamplifiers, equalizers, tone controls, active filters.

Under this product series, there is also a quad type μPC4574 with equivalent characteristics.

FEATURES

 Equivalent Input Noise Voltage (f = 1 kHz ) 4.5 nV/Hz (TYP.)

 Total Harmonic Distortion Rate (f = 20 Hz ~ 20 kHz) 0.002 % (TYP.)

 Slew Rate 7 V/µs (TYP.)

 Gain Bandwidth Product GBW (f = 100 kHz) 15 MHz (TYP.)

 Input Offset Voltage ±0.3 mV (TYP.)

 Operating Ambient Temperature -40 ~ +85 C

 Internal Frequency Compensation

 AEC-Q100 Compliance
