## Who designed the NE5532?

Signetics

The NE5532, also sold as SA5532, SE5532 and NG5532 (commonly called just 5532) is a dual monolithic, bipolar, internally compensated operational amplifier (op amp) for audio applications introduced by Signetics in 1979.

**What is dual operational amplifier?**

Dual Supply opamp has two supply rails with reference to GND to an opamp i.e +VCC and -VCC rails. Your applied voltage can swing between these two voltage levels. Hence, the output signal can swing only between these voltage(+VCC and -VCC) limits and they cannot exceed above these levels.

### When was op amp invented?

Karl D. Swartzel Jr. invented the first op-amp in 1967, and he originally conceived them to do mathematical operations in analog computers — thus the “operation” part of their name. We now use op-amps in many other applications, and they form the basis of many modern analog electronic circuits.

**What NE5532 used for?**

The NE5532 is a Dual Low Noise Op-Amp in 8-pin package commonly used as amplifiers in audio circuits for its noise immunity and high output drive capability. The Op-Amp is internally compensated for high unity gain with maximum output swing bandwidth, low distortion and high slew rate.

**What is NE5532 IC?**

NE5532 is a low noise dual op-amp IC i.e., the output of these devices will have lower distortion values. It has specified maximum limits for equivalent input noise voltage. It has high output-drive capability, high unity-gain and maximum-output-swing bandwidths, low distortion and high slew rate.

## When was the first commercial IC operational amplifier introduced?

In 1963, a 26-year-old engineer named Robert Widlar designed the first monolithic op-amp integrated circuit, the μA702, at Fairchild Semiconductor. It sold for US $300 a pop. Widlar followed up with an improved design, the μA709, cutting the cost to $70 and making the chip a huge commercial success.

**How an integrator is made using op amp?**

The operational amplifier integrator is an electronic integration circuit. Based on the operational amplifier (op-amp), it performs the mathematical operation of integration with respect to time; that is, its output voltage is proportional to the input voltage integrated over time.

**What is single supply op amp?**

A single-supply op amp is specifically designed to have a common-mode range which extends all the way to the negative supply (ground). Also, its output stage is usu- ally designed to swing close to ground.

### What is dual supply?

A Dual power supply is a regular direct current power supply. Many electronic circuits require a source of DC power. A dual power supply is used to power the electronic as well as electrical equipment. The dual power supply provides positive as well as negative potential with the ground.

**What are the recommended supply voltage ranges for the NE5532 dual op amp?**

NE5532 vs. LM358

NE5532 | LM358 | |
---|---|---|

Supply voltage | Up to +/- 22 V | Up to +/- 30 V |

Gain-bandwidth product | 10 MHz | 1-1.2 MHz |

Common-mode rejection ratio (CMRR) | Up to ~100 dB | Up to ~85 dB |

DC gain | Up to 100,000 | Up to 200,000 |

**What are the characteristics of a dual op amp?**

Utilizing the circuit designs perfected for quad op-amps, this dual op-amp features low power drain, a common mode input voltage range extending to ground/VEE, and single supply or split supply operation. The LM358 series is equivalent to one-half of an LM324.

## Is it possible to run an op amp from a single supply?

The answer is almost always yes. Operation of op amps from single supply voltages is useful when negative supply voltages are not available. Furthermore, certain ap- plications using high voltage and high current op amps can derive important benefits from single supply operation.

**What is an op op amp?**

Op amps are basically negative feedback (NFB) DC amplifiers. The op amp has a very large gain, the output can be hundreds of thousands times larger than the input. This huge gain however, is reduced using negative feedback to produce a circuit whose gain is stable and independent of the semiconductor characteristics.
