NE5532

Texas Instruments · Dual low-noise (audio) op-amp · SOIC-8

Dual low-noise, high-performance operational amplifier in a SOIC-8 package, the long-time standard for audio. It pairs ~5 nV/sqrtHz input noise with a 10 MHz gain-bandwidth and a 9 V/us slew rate, and drives low-impedance loads down to 600 ohm, so it suits mic and line preamps, active filters, and DAC output buffers. Runs from split supplies up to +/-20 V. Two independent amplifiers share the V+/V- rails.

Pinout

Pin Name Type Function
1 1OUT output Op-amp 1 output. Short-circuit protected; typical output short-circuit current 38 mA. Can swing near the supply rails driving loads ≥ 600 Ω.
2 1IN- input Op-amp 1 inverting input. Common-mode input voltage range ±13V typ at VCC=±15V; input bias current 200 nA typ.
3 1IN+ input Op-amp 1 noninverting input. Common-mode input voltage range ±13V typ; input-protection diodes clamp differential inputs above ~0.6V.
4 VCC- power_in Negative supply rail. Recommended operating range -5V to -15V (absolute max -18V). Total ICC per device is 6 mA typ (16 mA max).
5 2IN+ input Op-amp 2 noninverting input. Common-mode input voltage range ±13V typ; input-protection diodes clamp differential inputs above ~0.6V.
6 2IN- input Op-amp 2 inverting input. Common-mode input voltage range ±13V typ at VCC=±15V; input bias current 200 nA typ.
7 2OUT output Op-amp 2 output. Short-circuit protected; typical output short-circuit current 38 mA. Can swing near the supply rails driving loads ≥ 600 Ω.
8 VCC+ power_in Positive supply rail. Recommended operating range +5V to +15V (absolute max +18V). Bypass to VCC- with a local ceramic capacitor for low-noise operation.
