description
These devices consist of four independent, highgain frequency-compensated Norton operational
amplifiers that were designed specifically to
operate from a single supply over a wide range of
voltages. Operation from split supplies is also
possible. The low supply current drain is
essentially independent of the magnitude of the
supply voltage. These devices provide wide bandwidth and large output voltage swing.

NOTE 3: Clamp transistors are included that prevent the input voltages from swinging below ground more than approximately – 0.3 V. The
negative input currents that may result from large signal overdrive with capacitive input coupling must be limited externally to values
of approximately – 1 mA. Negative input currents in excess of – 4 mA causes the output voltage to drop to a low voltage. These
values apply for any one of the input terminals. If more than one of the input terminals are simultaneously driven negative, maximum
currents are reduced. Common-mode current biasing can be used to prevent negative input voltages.

APPLICATION INFORMATION
Norton (or current-differencing) amplifiers can be used in most standard general-purpose operational amplifier
applications. Performance as a dc amplifier in a single-power-supply mode is not as precise as a standard
integrated-circuit operational amplifier operating from dual supplies. Operation of the amplifier can best be
understood by noting that input currents are differenced at the inverting input terminal and this current then flows
through the external feedback resistor to produce the output voltage. Common-mode current biasing is generally
useful to allow operating with signal levels near (or even below) ground.
Internal transistors clamp negative input voltages at approximately – 0.3 V but the magnitude of current flow has to
be limited by the external input network. For operation at high temperature, this limit should be approximately
– 100 µA.
Noise immunity of a Norton amplifier is less than that of standard bipolar amplifiers. Circuit layout is more critical since
coupling from the output to the noninverting input can cause oscillations. Care must also be exercised when driving
either input from a low-impedance source. A limiting resistor should be placed in series with the input lead to limit the
peak input current. Current up to 20 mA will not damage the device, but the current mirror on the noninverting input
will saturate and cause a loss of mirror gain at higher current levels, especially at high operating temperatures.
