"Description
The OPA2810 is a dual-channel, FET-input, voltage-feedback operational amplifier with low input bias current. The OPA2810 is unity-gain stable with a small-signal unity-gain bandwidth of 105 MHz, and offers excellent DC precision and dynamic AC performance at a low quiescent current (IQ) of 3.6 mA per channel (typical). The OPA2810 is fabricated on Texas Instrument’s proprietary, high-speed SiGe BiCMOS process and achieves significant performance improvements over comparable FET-input amplifiers at similar levels of quiescent power. With a gain-bandwidth product (GBWP) of 70 MHz, slew-rate of 192 V/µs, and voltage low noise of 6 nV/√Hz, the OPA2810 is well suited for use in a wide range of high fidelity data acquisition and signal processing applications."
To je nasleđe nekad jako moćnih Burr Brown, koje je Texas kupio.
Pored toga što su moćna i vrlo stara firma, kupovinom gomile firmi, poput: National Semiconductors, Unitrode, Burr Brown i sličnih, dobili su dodatnu i moćnu bazu znanja koja im je dala novi "vetar u leđa".
Tri pomenute firme su bili avangarda u analognoj i smps tehnici.
Sve što je LMxxxxx je bilo National, sve što je OPAxxxx je bilo Burr Brown i sve što je UCxxxx je bilo Unitrode...
