Instrumentation Amplifier Applications
For applications that require a complete low-power
instrumentation amplifier, refer to the MAX4194–
MAX4197 data sheet. Some differential to single-ended
voltage amplifier applications that do not require a high
input impedance can use the MAX4198/MAX4199 for
gains of +1V/V or +10V/V. The MAX4198/MAX4199 can
also be used as an instrumentation amplifier building
block. The circuit of Figure 7 takes advantage of the
10pA (max), 0.1pA (typ) bias current of the MAX406A
to form an instrumentation amplifier similar to the
MAX4194 family, except with lower input bias currents.
The MAX406A's low 1.2A supply current maintains a
low overall supply current.
