Sonic Imagery Labs 995FET High Performance Discrete Opamp

The 995FET-Ticha is a high performance discrete operational amplifier designed for professional audio applications and areas where ultra-low noise, extremely low distortion and highly linear uncolored operation is required. A true super matched pair FET input stage is incorporated to provide superior sound quality and speed for exceptional audio performance. This in combination with high output drive capability and excellent dc performance allows use in a wide variety of demanding applications. In addition, the 995FET’s wide output swing provides increased headroom making it ideal for use in any audio circuit.

The 995FET-Ticha opamp can be operated from ±10V to ±25V power supplies. Input cascode circuitry provides excellent common-mode rejection and maintains low input bias current over its wide input voltage range, minimizing distortion. The 995FET discrete op amp is unity-gain stable and provides excellent dynamic behavior over a wide range of load conditions.

The 995FET-Ticha discrete opamp was designed as an enhanced upgrade replacement for the Millennia Media Series MM-99, MM990, Forssell Technologies JFET-993, JFET-992, or other similar end of life or obsolete FET based op-amp gain blocks. The pinouts conform to the 990/2520 package type, allowing direct replacement.
