Detailed Description
Featuring a maximized ratio of gain bandwidth to
supply current, low operating supply voltage, low input
bias current, and rail-to-rail inputs and outputs, the
MAX9914–MAX9917 are an excellent choice for preci-
sion or general-purpose low-current, low-voltage, bat-
tery-powered applications. These CMOS devices
consume an ultra-low 20A (typ) supply current and a
200V (typ) offset voltage. For additional power
conservation, the MAX9914/MAX9917 feature a low-
power shutdown mode that reduces supply current to
1nA (typ), and puts the amplifiers’ output in a high-
impedance state. These devices are unity-gain stable
with a 1MHz gain-bandwidth product driving capacitive
loads up to 30pF. The capacitive load can be
increased to 100pF when the amplifier is configured for
a 10V/V gain.
Rail-to-Rail Inputs and Outputs
The MAX9914–MAX9917 amplifiers all have a parallel-
connected n- and p-channel differential input stage that
allows an input common-mode voltage range that
extends 100mV beyond the positive and negative sup-
ply rails, with excellent common-mode rejection.
The MAX9914–MAX9917 are capable of driving the out-
put to within 5mV of both supply rails with a 100k
Ω load.
These devices can drive a 5k
Ω load with swings to within
60mV of the rails. Figure 1 shows no clipping at the out-
put voltage swing of the MAX9914–MAX9917 configured
as a unity-gain buffer powered from a single 3V supply.
Low Input Bias Current
The MAX9914–MAX9917 feature ultra-low 1pA (typ)
input bias current. The variation in the input bias
current is minimal with changes in the input voltage due
to very high input impedance (in the order of 1G
Ω).
Applications Information
Driving Capacitive Loads
The MAX9914–MAX9917 amplifiers are unity-gain
stable for loads up to 30pF. However, the capacitive
load can be increased to 100pF when the amplifier is
configured for a minimum gain of 10V/V.
Applications that require greater capacitive drive
capability should use an isolation resistor between the
output and the capacitive load (Figure 2). Also, in
unity-gain applications with relatively small RL (about
5k
Ω), the capacitive load can be increased up to 100pF.
