•
The RC5532 is a high performance, dual low noise operational amplifier. Compared to standard dual operational
amplifiers, such as the RC747, it shows better noise performance, improved output drive capability, and considerably
higher small-signal and power bandwidths.
Small signal bandwidth – 10 MHz
Output drive capability – 600Ω, 10 VRMS
Input noise voltage – 5 nV/ Hz
DC voltage gain – 50,000
AC voltage gain – 2200 at 10 KHz
Power bandwidth – 140 KHz
Slew rate – 8 V/µS
Large supply voltage range – ±3V to ±20V
This makes the device especially suitable for application in
high quality and professional audio equipment, instrumentation, control circuits, and telephone channel amplifiers.
The op amp is internally compensated for gains equal to one.
If very low noise is of prime importance, it is recommended
that the RC5532A version be used which has guaranteed
noise specifications.

Notes:
1. Diodes protect the inputs against over-voltage. Therefore, unless current-limiting resistors are used, large currents will flow
if the differential input voltage exceeds 0.6V. Maximum input current should be limited to ±10mA.
