Integrerade kretsar

IC

Integrerade kretsar ("IC-kretsar") är kretsar där en viss logisk eller analog funktion realiserats genom att kombinera ett antal transistorer på samma kiselbricka. Detta gör att samma funktion kan realiseras på mindre yta än om den realiserats med diskreta transistorer.

Det finns huvudsakligen två typer av kapsling för integrerade kretsar; hålmonterade (DIP-) och ytmonterade (SO-). De flesta kretsar finns i både hålmonterat och ytmonterat utförande.

  LM4562MA SO-8 dual op-amp hifi
Dual High Performance, High Fidelity Audio Operational Amplifier The LM4562 is part of the ultra-low distortion, low noise, high slew rate operational amplifier series optimized and fully specified for high performance, high fidelity applications. Combining advanced leading-edge process technology with state-of-the-art circuit design, the LM4562 audio operational amplifiers deliver superior audio signal amplification for outstanding audio performance. The LM4562 combines extremely low voltage noise density (2.7nV/vHz) with vanishingly low THD+N (0.00003%) to easily satisfy the most demanding audio applications. To ensure that the most challenging loads are driven without compromise, the LM4562 has a high slew rate of +/-20V/µs and an output current capability of +/-26mA. Further, dynamic range is maximized by an output stage that drives 2kOhm loads to within 1V of either power supply voltage and to within 1.4V when driving 600ohm loads. The LM4562's outstanding CMRR (120dB), PSRR (120dB), and Vos (0.1mV) give the amplifier excellent operational amplifier DC performance. The LM4562 has a wide supply range of +/-2.5V to +/-17V. Over this supply range the LM4562s input circuitry maintains excellent common-mode and power supply rejection, as well as maintaining its low input bias current. The LM4562 is unity gain stable. This Audio Operational Amplifier achieves outstanding AC performance while driving complex loads with values as high as 100pF.
