| This listing is for one (qty1) Sonic Imagery Labs Model 992Enh-Ticha Discrete Opamp. Model 992Enh-Ticha Discrete Operational Amplifier (DIP8 single) No other Discrete Op-Amp on the market comes close to our fully production tested performance and 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 resolution performance. Model 992Enh Datasheet and Specifications PDF General Description: 992Enh-Ticha Discrete Operational Amplifier DIP8 The 992Enh-Ticha is a single high performance discrete operational amplifier designed for professional audio applications and areas where ultra-low noise, low distortion and highly linear uncolored performance is required. It was designed as an performance upgrade replacement universal single op-amp gain block. The pin outs conform to the standard 8 pin dual in-line monolithic IC package, allowing direct replacement. See table 1. on page 6 of data sheet for typical 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 992Enh-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 992 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 tested for noise, offset and distortion and meet or exceed published specifications. The 992Enh-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 992Enh 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 992Enh 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 ±3.6V to ±20V for low power applications. Contact us and ask about the Model 992LV-Enh-Ticha See Also |
