Applications Information
The MAX5426 is ideal for programmable instrumentation
amplifier applications. The typical application circuit of
Figure 1 uses the MAX5426 in classical instrumentation
amplifier configurations. Two digital inputs set the gain to
1, 2, 4, or 8.
Op Amp Selection Guidelines
Selection of an op amp for instrumentation amplifier cir-
cuits depends on the accuracy requirements of the
specific application. General guidelines are to choose
an op amp with sufficient open-loop gain, low input-off-
set voltage, and a high common-mode rejection ratio.
High open-loop gain is needed to increase the gain
accuracy, while low input-offset voltage and low input-
offset current help meet gain and offset requirements.
Other parameters such as low input capacitance, low
input bias current, high input common-mode range,
and low noise often need to be considered for a wide
input voltage range stability and AC considerations.
The MAX427 is an excellent choice to use with the
MAX5426.
Stereo Audio-Taper Attenuator
Figure 2 shows the application of the MAX5426 as a dual
attenuator that can be used in stereo audio systems.
Power Supplies and Bypassing
The MAX5426 operates from dual ±5V to ±15V sup-
plies. In many applications the MAX5426 does not
require bypassing. If power-supply noise is excessive,
bypass V
DD
and V
SS
with 0.1μF ceramic capacitors to
GND.
Layout Concerns
For best performance, reduce parasitic board capaci-
tance by minimizing the circuit board trace from ampli-
fier outputs to inverting inputs. Also choose op amps
with low input capacitance.
