Description
The RC5532 is a high performance, dual low noise opera-
tional amplifier. Compared to standard dual operational
amplifiers, such as the RC747, it shows better noise perfor-
mance, improved output drive capability, and considerably
higher small-signal and power bandwidths.
This makes the device especially suitable for application in
high quality and professional audio equipment, instrumenta-
tion, 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. Functional operation under any of these conditions is NOT implied.
2. For supply voltages less than 15V, the absolute maximum input voltage is equal to the supply voltage.
3. Short circuit to ground on one amplifier only.

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.
