CLC405

Low-Cost, Low-Power, 110MHz Op Amp with Disable

General Description

Features

■

The CLC405 is a low-cost, wideband (110MHz) op amp featur-

ing a TTL-compatible disable which quickly switches off in 18ns

and back on in 40ns. While disabled, the CLC405 has a very high

input/output impedance and its total power consumption drops to

a mere 8mW. When enabled, the CLC405 consumes only 35mW

and can source or sink an output current of 60mA. These

features make the CLC405 a versatile, high-speed solution for

demanding applications that are sensitive to both power and cost.

Low-cost

■

Very low input bias current: 100nA

■

High input impedance: 6MΩ

110MHz -3dB bandwidth (A = +2)

Low power: I = 3.5mA

Ultra-fast enable/disable times

High output current: 60mA

Applications

Utilizing National’s proven architectures, this current feedback

amplifier surpasses the performance of alternative solutions and

sets new standards for low power at a low price. This power-

conserving op amp achieves low distortion with -72dBc and

-70dBc for second and third harmonics respectively. Many high

source impedance applications will benefit from the CLC405’s

6MΩ input impedance. And finally, designers will have a bipolar

part with an exceptionally low 100nA non-inverting bias current.

High resolution monitors

With 0.1dB flatness to 50MHz and low differential gain and phase

errors, the CLC405 is an ideal part for professional video

processing and distribution. However, the 110MHz -3dB band-

Frequency Response (A_v= +2V/V)

width (A = +2) coupled with a 350V/µs slew rate also make the

CLC405 a perfect choice in cost-sensitive applications such as

video monitors, fax machines, copiers, and CATV systems.
