This listing is one piece of TI OPA128KM instrument grade opamp. It was designed for the most stringent design requirement. 

Audiophiles have used it in the DAC output with excellent result and some even named it "King of the opamps". Sonic-wise the opamp gives superb resolution, silky high frequencies and fluid sound. These are end of life parts as TI has replaced this opamp with much cheaper alternatives.

For this listing, these are used parts , but the leads are in full length and the parts are in excellent condition. The leads are tinned( original leads are gold plated. OPA128 has been EOL for a long time. If gold-plated lead OPA128 components are available at a good price, buyers can use their discretion to determine whether they are genuine or not.

The listing is for one piece.
