NE5532Dual low-noise operational amplifier
Low-noise gain for two analog signal paths.
NE5532 contains two low-noise bipolar-input operational amplifiers. It is widely used for analog and audio stages where voltage noise, drive capability and predictable feedback behavior matter. Our example uses one channel at a gain of three and the other as a buffer. Both channels receive 0.50 V, giving ideal DC outputs of 1.50 V and 0.50 V from ±15 V rails. The reference uses TI NE5532 commercial-grade PDIP-8 and SOIC-8 parts. Input bias current and source resistance deserve attention: low voltage noise does not mean negligible input-current error.

NE5532 at a glance
Follow the labeled connections and functional stages
How it works
3 stages · Explore one step at a time
Compare each input pair
The bipolar differential inputs offer low voltage noise, but draw bias current. The resulting error depends on source resistance and the feedback network.
Set two different gains
Channel A uses 20 kΩ feedback and 10 kΩ to the 0 V midpoint, giving a gain of three. Channel B directly feeds its output back to its negative input, giving unity gain.
Check headroom and speed
With a 0.50 V input, the ideal outputs are 1.50 V and 0.50 V. Real output also depends on input offset, resistor accuracy, loading, noise and signal frequency.

Connect it, step by step
Follow the component values and pin connections
Connect power
Use +15 V at pin 8 and −15 V at pin 4, with a 100 nF bypass from each rail to signal ground.
Wire the feedback
Add the 20 kΩ / 10 kΩ network to channel A and join pins 7 and 6 for channel B.
Read both outputs
At a nominal input of 0.50 V, expect about 1.50 V from A and 0.50 V from B under light DC loading.

Input stages
The bipolar differential inputs offer low voltage noise, but draw bias current. The resulting error depends on source resistance and the feedback network.
Gain and compensation
Each channel has an internal voltage-gain path and frequency compensation.
Output drivers
Separate output drivers serve the two channels. Output swing depends on load and rail headroom; short-circuit protection is not a continuous-load rating.
