Applications Information
Ground Sensing
The common-mode input range of the MAX4470 family
extends down to ground, and offers excellent common-
mode rejection. These devices are guaranteed not to
undergo phase reversal when the input is overdriven.
Power Supplies and Layout
The MAX4470 family operates from a single +1.8V to
+5.5V power supply. Bypass power supplies with a
0.1F ceramic capacitor placed close to the VDD pin.
Ground layout improves performance by decreasing the
amount of stray capacitance and noise at the op amp’s
inputs and outputs. To decrease stray capacitance, mini-
mize PC board lengths and resistor leads, and place
external components close to the op amps’ pins.
Bandwidth
The MAX4470/MAX4471/MAX4472 are internally
compensated for unity-gain stability and have a typical
gain-bandwidth of 9kHz. The MAX4464/MAX4474 have
a 40kHz typical gain-bandwidth and are stable for a
gain of +5V/V or greater.
Stability
The MAX4464/MAX4470/MAX4471/MAX4472/MAX4474
maintain stability in their minimum gain configuration
while driving capacitive loads. Although this product
family is primarily designed for low-frequency applica-
tions, good layout is extremely important because low-
power requirements demand high-impedance circuits.
The layout should also minimize stray capacitance at the
amplifier inputs. However some stray capacitance may
be unavoidable, and it may be necessary to add a 2pF
to 10pF capacitor across the feedback resistor as shown
in Figure 1. Select the smallest capacitor value that
ensures stability.
