Do op amps sound different?

MYTH: MOST OP AMPS SOUND DIFFERENT – There’s a general perception that op amps sound different. Many gear manufactures tout op amp brands and part numbers in their marketing literature. The $3 OPA2134 is supposed to sound much better than the $1 NE5532 and the $10 AD8610 is supposed to sound better still.

What is a JFET op amp?

The TL082 JFET-input operational amplifier incorporates well-matched, high-voltage JFET and bipolar transistors in a monolithic integrated circuit. The device features high slew rates, low input bias and offset currents, and low offset-voltage temperature coefficient.

How does op amp affect sound?

When opamps are driving headphones directly one or more of their limits can easily be reached. Before those limits are reached they sound the same, assuming they are suited for that task. When current limits are reached some opamps behave strangely or just clip. Some even oscillate at that moment.

How do you choose an op amp?

The first decision to make when choosing the op-amp for an audio application is usually between bipolar and JFET input transistors, and for most audio circuits both perform equally well. JFET op-amps have high input impedances so voltage noise is higher, but current noise will be lower.

What is the difference between mosfet and JFET?

The input impedance in the case of JFET is much smaller, primarily around the order 108 Ω. The input impedance in the case of MOSFET is much higher, primarily around the order 1010-1015 Ω because it has a very small current leakage. JFET only operates on the depletion mode.

What is log and antilog amplifier?

Advertisements. The electronic circuits which perform the mathematical operations such as logarithm and anti-logarithm (exponential) with an amplification are called as Logarithmic amplifier and Anti-Logarithmic amplifier respectively.

What is the difference between CMOS and JFET op amps?

and JFET input op amps is typically many orders of magnitude lower than in bipolar amplifiers, the input resistance in CMOS and JFET op amps is much higher than in bipolar devices; 6×1012(Tera-Ω) in the OPA2156, 1 TΩin the OPA828, and 1 GΩin the bipolar OPA2210 — a typical Rin is even lower in most

What is the difference between JFET and BJT op-amps?

Part 3 examines various op amps and their key performance specs from a perspective of audio design.] Op-amps with JFET inputs tend to have higher voltage noise and lower current noise than BJTinput types, and therefore give a better noise performance with high source resistances.

What is the temperature range of FET op amp?

This FET-Input op-amp with an operating free-air temperature range of 40°C to 85°C has a wide gain-bandwidth of 8 MHz and a slew rate of 20 V/us. This amplifier is ideal to provide superior sound quality and speed for exceptional audio performance.

What is the best op amp with no bias and offset?

The TL072 is one of the most popular op-amps, having very-high-impedance inputs, with effectively zero bias and offset currents. The JFET input devices give their best noise performance at medium impedances, in the range 1–10 kO.
