GainBlock Difference Amplifier
Preliminary Information
General Description
The MIC7201 difference amplifier is an analog gain block
designed to convert a differential signal to a signal-ended
signal. It features an extended common-mode range that
includes rail-to-rail input/output capabilities. The part is pack-
aged in the SOT-23-5 IttyBitty package.
The MIC7201 is designed using the MIC7101 operational
amplifier plus well-matched monolithic resistors to provide a
unity-gain stable differential input to signal-ended output
amplifier that requires a minimum of external components.
Performance is guaranteed from 2.2V through 10V.
Features
Operates from 2.2V to 10V
±
1% typical gain error
0.6mA typical supply current at 2.2V
400kHz bandwidth
Small SOT-23-5 package
Suitable for driving capacitive loads
Applications
Cellular telephones
Digital audio systems
Mobile communications
Portable computers and PDAs

Difference Amplifier Behavior
The desired 100mV, 400Hz differential sinusoidal signal is shown applied to
inputs V
and V
IN+
. A 500mV, 5kHz square-wave “noise” signal is super-
imposed on both V
IN–
and V
IN+
.
These signals demonstrate the noise cancellation ability of the MIC7201.
The output (V
) shows the recovered single-ended 200mV peak-to-peak,
400Hz sine wave.
