Micropower, Rail-to-Rail, fixed-gain, single, GainAmp op amp. Inverting gain 0.25V/V, noninverting gain 1.25V/V, -3dB BW 200kHZ.
General DescriptionThe MAX4074–MAX4078 GainAmp™ op amp family
combines low-cost Rail-to-Rail®op amps with precision
internal gain-setting resistors. Factory-trimmed on-chip
resistors decrease design size, cost, and layout, and
provide 0.1% gain accuracy. Fixed inverting gains from
-0.25V/V to -100V/V or noninverting gains from +1.25V/V
to +101V/V are available. These devices operate from a
single +2.5V to +5.5V supply and consume just 34µA.
GainAmp amplifiers are optimally compensated for each
gain version, achieving gain bandwidth (GBW) products
up to 4MHz (AV= +25V/V to +101V/V). High-voltage
fault protection withstands ±17V at either input without
damage or excessive current draw (MAX4074/MAX4075
only).
Two versions are available in this amplifier family. The
MAX4076/MAX4077/MAX4078 are single/dual/quad
open-loop, unity-gain-stable op amps, and the
MAX4074/MAX4075 are single/dual fixed-gain op
amps. The input common-mode voltage range of the
open-loop amplifiers extends from 150mV below the
negative supply to within 1.2V of the positive supply.
The GainAmp outputs can swing rail-to-rail and drive a
1kΩload while maintaining excellent DC accuracy
(MAX4074/MAX4075 only). The amplifiers are stable for
capacitive loads up to 100pF.
For space-critical applications, the MAX4074/MAX4076
are available in space-saving SOT23-5 packages.

Note 3:The input common-mode range for IN_+ is guaranteed by a functional test. A similar test is done on the IN_- input. See the
Applications Informationsection for more information on the input voltage range of the GainAmps.
Note 4:For AV= -0.5V/V and AV= -0.25V/V, the output voltage swing may be limited by the input voltage range.
Note 5:Includes noise from on-chip resistors.
Note 6:The gain accuracy test is performed with the GainAmps in the noninverting configuration. The output voltage swing is limit-
ed by the input voltage range for certain gains and supply voltage conditions. For situations where theoutput voltage swing
is limited by the valid input range, the output limits are adjusted accordingly.

Pin Description
_______________Detailed DescriptionMaxim’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 10kΩload while
maintaining excellent DC accuracy.
Open-Loop Op AmpsThe 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 -3dBband-
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 ResistorsMaxim’s proprietary laser trimming techniques allow
RF/RGvalues (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 (RF/RG) 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.
