CLC426 - National Semiconductor

CLC426 Wideband/ Low-Noise/ Voltage Feedback Op Amp

The CLC426 combines an enhanced voltage-feedback architecture with an advanced complementary bipolar process to provide a high-speed op amp with very low noise (1.6nV/√Hz & 2.0pA/√Hz) and distortion (-62/-68dBc 2nd/3rd harmonics at 1Vpp and 10MHz). Providing a wide 230MHz gain-bandwidth product, a fast 400V/µs slew rate and very quick 16ns settling time to 0.
