Beskrivning

Detta är en diskret op-amp som direkt kan ersätta många IC baserade op förstärkare.
En professionell modul med mycket låg brusnivå, låg distorsion och bra linjaritet.

Modell 992 har en single op amp funktion. 

Många föredrar diskreta komponenter och jämfört med en integrerad op-amp, då den diskreta har mycket färre transistorer i signalkedjan och påverkar ljudet mindre för en naturligare ljudbild.

Denna enhet är byggd av precissionsanpassade diskreta komponenter med mycket bra data.

Enheten är ca 25 X 25 mm ytmässigt. Smidigt liten och för att få kompakthet så är den primärt byggd med diskreta SMD kretsar på båda sidorna av det lilla kretskortet.

Man kan använda denna i nykonstruktioner eller som många gör, byta ut integrerade komponenterna, då den är direkt pinkompatibel med många. Se nedan.
Med hjälp av socklar kan man lätt justera vinel och höjd i en befintlig apparat om andra komponenter är i vägen. Se länk modulinformation, nedan.

Kan ersätta följande op-ampar; AD797, AD811, AD844, AD8610, CA3130, CA3160, LM301N, LM308N, LM741N, NE531, NE5534, OP27, OPA627, OPA603, OPA134, OPA604, LT1122, AD8610, CA5130E, CA5160E, SE5532, LM201A

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 992Enh-Ticha Discrete OpAmp achieves a new standard of excellence in noise performance with 0.89nV/Rt.Hz @1kHz noise. This ultralow noise is combined with excellent high speed specifications (gain-bandwidth product >50MHz), immeasurably low distortion output, and true precision parameters (>200µV offset voltage, 118dB voltage gain open loop). Although the 992Enh-Ticha’s input stage operates at nearly 1mA of collector current to achieve low voltage noise, input bias current is typically less than 1uA.

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 or temperature.

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 or headphones directly 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. It is a true drop-in replacement upgrade. 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. The 992Enh-Ticha Discrete op-amp voltage noise is less than the thermal noise of a 50 Ohm resistor. Therefore, even in very low source impedance transducer or audio amplifier applications, the 992Enh-Ticha’s contribution to total system noise will be negligible.

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.
