Description
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. 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 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. 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.

Product review & video
so yeah discreet op-amps this is our own offering to the as there's a few out there now ice the icy op-amps some of them perform very good very well you know they have massive open loop gain they have low offset DC offset yeah they draw a very little current you know on paper they perform very well trouble is the human ear doesn't hear the way test equipment measures you know and everyone's he is different as well so it really is in the year of the beholder what sounds good you know I see op amps for starters it's on a tiny die and that means every transistor and every resistor it's gonna be it's gonna have a lower dissipation available to it you know and the amount of gain blocks they've added on to their to deal with the performance is probably gonna get in the way the best sounding audio you know so they're not designed to IC op amps are not designed really purely for audio you know
