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
0.1μF ceramic capacitor placed close to the V
DD
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 2. Select the smallest capacitor value that
ensures stability.
