NJM2068 LOW-NOISE DUAL OPERATIONAL AMPLIFIER

Transcription

1 LOW-NOISE DUAL OPERATIONAL AMPLIFIER NJM26 GENERAL DESCRIPTION The NJM26 is a high performance, low noise dual operational amplifier. This amplifier features popular pin-out, superior noise performance, and superior total harmonic distortion. This amplifier also features guaranteed noise performance with substantially higher gain-bandwidth product and slew rate, which far exceeds that of the type amplifier. The specially designed low noise input transistors allow the NJM26 to be used in very low noise signal processing applications such as audio preamplifiers and servo error amplifier. The D-Rank type products(njm26dd/ld/md) have specified maximum limits for equivalent input noise voltage.
