DESCRIPTION
The CLC400 is a high speed, fast setting operational
amplifier designed for low gain applications.
Constructed using a unique, proprietary design and
an advanced complementary bipolar process, the
CLC400 offers performance far beyond that normally
offered by ordinary monolithic op amps. In addition,
unlike many other high speed op amps the CLC400
offers both high performance and stability without the
need for compensation circuitry - even at a gain of
+1.
The fast 12ns settling to 0.05% and its ability to drive
capacitive loads makes the CLC400 an ideal flash
A/D driver. The wide bandwidth of 200MHz and the
very linear phase ensure unsurpassed signal fidelity.
Systems employing digital to analog converters also
benefit from the use of the CLC400 - especially if
linearity and drive levels are important to system
performance.
The CLC400 provides a simple, high performance
solution for video distribution and line driving
applications. The 50mA output current and
guaranteed specifications for 100Ω loads provide
ample drive capability and assured performance.
The CLC400 is based on proprietary op amp topology
that uses current feedback instead of the usual
voltage feedback. This unique design has many
advantages over conventional designs (such as
settling time that is relatively independent of gain), yet
it is used in basically the same way (see the gain
equations in Figure 17 and Figure 18). However, an
understanding of the topology will aid in achieving the
best performance. The following discussion will
proceed for the non-inverting gain configuration with
the inverting mode analysis being very similar.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
