DESCRIPTION
The L6242 is a monolithic integrated circuit in SO-20
package intended for use as a dual power opera-
tional amplifier. It is particularly indicated for driv-
ing inductive loads as linear motor, and finds ap-
plication in Hard Disc, Compact-Disc, etc.
The two power operational amplifiers are control-
led by a common enable input.

... I Output Leakage Current ol APPLICATION INFORMATIONS Figure 1 shows the L6242 configurated as a tran- sconductance amplifier, in order to drive linear motors as Voice Coil (VCM). The L6242 provides the power section of the Transconductance Am- plifier. The two OP AMP are configurated one as inverting and the other as noninverting amplifier, with the same gain ...

... This is to avoid anomalous interface with the logic signals generally a good idea to connect a non inductive capacitor (typically 100nF) between the pins VS and GND. In other cases it may be necessary to also place a by-pass capacitor between the pins Vref and GND. L6242 3/5 ...
