_______________Detailed Desc ription
The MAX4198/MAX4199 are precision low-power differ-
ential amplifiers with factory-trimmed internal gain-set-
ting resistors. The MAX4198 is trimmed to a gain of
+1V/V and the MAX4199 is trimmed to a gain of +10V/V.
Input S tage
The Functional Diagram shows the internal structure of
the MAX4198/MAX4199. Although the resistors are pre-
cision matched, their absolute value varies by ±25%.
The typical input impedance for the MAX4198 is 50k
for the noninverting input and 25k
for the inverting
input. The typical input impedance for the MAX4199 is
275k
for the noninverting input and 25k
for the
inverting input.
The common-mode inputs of the internal op amp can
range from V
EE
to (V
CC
- 1.1V). Although the inputs to
the internal op amp are not rail-to-rail, the internal resis-
tors form a voltage divider that extends the input com-
mon-mode range beyond-the-rails for the MAX4198.
The overall input range of the MAX4198 extends 100mV
beyond-the-rails without adversely affecting common-
mode rejection or undergoing phase reversal (V
CC
=
5V). The MAX4199 input common-mode range extends
from 100mV below the negative rail to (V
CC
- 1V) (see
the Input Common-Mode Voltage Range vs. Supply
Voltage graph in the Typical Operating Characteristics).
