IC-LOW NOISE VOLT FBK AMP

Category:

Description

Item Description:

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 0.05% , the CLC426 is the ideal choice for high speed applications requiring a very wide dynamic range such as an input buffer for high-resolution analog-to digital converters. The CLC426 is internally compensated for gains ≥ 2V/V and can easily be externally compensated for unity-gain stability in applications such as wideband low-noise integrators. The CLC426 is also equipped with external supply current adjustment which allows the user to optimize power, bandwidth, noise and distortion performance for each application. The CLC426’s combination of speed, low noise and distortion and low dc errors will allow high-speed signal conditioning applications to achieve the highest signal-to-noise performance. To reduce design times and assist board layout, the CLC426 is supported by an evaluation board and SPICE simulation model available from National. For even higher gain-bandwidth voltage-feedback op amps see the 1.9GHz CLC425 (Av ≥ 10V/V) or the 5.0GHz CLC422 (Av ≥ 30V/V).
