Pin Description
_______________Detailed Description
Maxim’s GainAmp fixed-gain amplifiers combine a low-
cost rail-to-rail op amp with internal gain-setting resis-
tors. Factory-trimmed on-chip resistors provide 0.1%
gain accuracy while decreasing design size, cost, and
layout. There are two versions in this amplifier family:
single/dual/quad open-loop, unity-gain-stable devices
(MAX4076/MAX4077/MAX4078), and single/dual fixed-
gain devices (MAX4074/MAX4075). All amplifiers fea-
ture rail-to-rail outputs and drive a 10k
load while
maintaining excellent DC accuracy.
Open-Loop Op Amps
The single/dual/quad MAX4076/MAX4077/MAX4078 are
low-power, open-loop op amps with rail-to-rail outputs.
These devices are compensated for unity-gain stability
and feature a GBW product of 230kHz. The common-
mode range extends from 150mV below the negative
rail to within 1.2V of the positive rail. These high-perfor-
mance op amps serve as the core for this family of
GainAmp fixed-gain amplifiers. Although the -3dB band-
width will not correspond to that of a fixed-gain amplifier
in higher gain configurations, these open-loop op amps
can be used to prototype designs.
Internal Gain-Setting Resistors
Maxim’s proprietary laser trimming techniques allow

values (Figure 1) that produce many different
gain configurations. These GainAmp fixed-gain ampli-
fiers feature a negative-feedback resistor network that
is laser trimmed to provide a gain-setting feedback
ratio (R

) with 0.1% typical accuracy. The standard
op amp pinouts allow the GainAmp fixed-gain ampli-
fiers to plug directly into existing board designs, easily
replacing op amps-plus-resistor gain blocks.
