... 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 ...

... V cc CLC405 Figure 1 illustrates the internal enable/disable opera- tion of the CLC405. When pin 8 is left floating or is tied and pulls tail current through the cc CLC405 bias circuitry. 0.8V above the supply midpoint, Q1 stops tail current from flowing in the CLC405 circuitry. The CLC405 is now disabled ...

... The value for R shown in Figure out supplies. Wideband Digital PGA As shown on the front page, the CLC405 is easily con- figured as a digitally controlled programmable gain +5V amplifier. Make a PGA by configuring several amplifiers + C at required gains. Keep R 3 6.8 fd for each different gain. Use a TTL decoder that has ...

... Equalizers restore the attenuated com- ponents of this signal. The circuit in Figure amp equalizer. The RC networks peak the response of the CLC405 at higher frequencies. restores cable-attenuated frequencies. Graph 2 shows how the equalizer actually restored a digital word through 150 meters of coaxial cable. ...
