Description

SonicImageryLabs 994Enh-Ticha Dual HD Discrete OpAmp
This listing is for one (qty1) Sonic Imagery Labs Model 994Enh-Ticha Dual Discrete Opamp.
Model 994Enh-Ticha Dual Discrete Operational Amplifier (DIP8dual)
No other Discrete Op-Amp on the market comes close to our fully production tested specifications.
Don't waste your time and money on "High Definition Audio Modules" which require a ground wire to operate and have barely enough gain to remain stable and purport to have great THD spec's. Don't waste your money on supposedly hand matched leaded transistors for differential input pairs, a few minutes after warm up they aren't matched anymore and your CMRR and offset is now gone. There's a lot of crap out there. Download our datasheet, read, and understand that knowledge is the first step to high performance. Sonic Imagery Labs engineers it's products for high performance.

General Description:
994Enh-Ticha Discrete Operational Amplifier DIP8
The 994Enh-Ticha is a dual high performance discrete operational amplifier designed for professional audio applications and areas where ultralow noise, low distortion and highly linear uncolored performance is required. It was designed as an performance upgrade replacement universal dual op-amp gain block. The pinouts conform to the standard 8 pin dual in-line monolithic IC package, allowing direct replacement. See table 1. on page 6 of datasheet for typical dual monolithic operational amplifiers which can be upgraded.
The all-discrete SMT design utilizes an ultra-precision differential super-matched transistor pair specifically designed to meet the requirements of ultra-low noise and ultra-low THD audio systems. In addition to the enhanced input stage, the 994Enh-Ticha uses high performance temperature stable power supply independent current sources. Supply independent current sources allow the bias to remain locked at the optimum operating point regardless of supply voltage.
Dual matched pair temperature stable current mirrors, dual matched pair active current loads give the Model 994 it's outstanding power supply rejection performance. The enhanced low distortion Class-A output driver stage can sink or source 150mA allowing this module to drive transformers if required. Each amplifier is matched for noise, offset and distortion to within 0.1% of each other and both amplifier channels meet or exceed published specifications.
The 994Enh-Ticha op amp is a true bipolar op amp and behaves as such. It does not require a flying ground lead as do other designs on the market. Because the 994Enh is a true op amp, It can also be operated in single supply applications as long as external biasing has been implemented correctly.
Because of the 994Enh high current drive capability, supporting circuitry impedances can be scaled down within the application circuit. This can reduce the overall system noise, without increased distortion. Sonic Imagery Labs also can provide a variation of this model that can operate down to
±4.5V
for low power applications. Contact us and ask about the 994LV-Enh DUAL.
