General Description
The MAX406/MAX407/MAX409/MAX417-MAX419 are
single, dual, and quad low-voltage, micropower, precision
op amps designed for batteryoperated systems. They tea-
ture a supply current of less than 1.2pA per amplifier that is
relatively constant over the entire supply range, which repre-
sents a 15 to 20 times improvement over industry-standard
micropower op amps. A unique output stage enables these
op amps to operate at ultra-low supply current while main-
taining linearity under loaded conditions. In addition, the out-
put is capable of sourcing 1.8mA when powered by a 9V
battery.
The common-mode input-voltage range extends from the
negative rail to within 1.1V of the positive supply (for the
singles, 1.2V for the duals and quads), and the output stage
swings rail-to-rail. The entire family is designed to maintain
good DC characteristics over the operating temperature
range, minimizing the input referred errors.
The MAX406 is a single op amp with two modes of opera-
tion: compensated mode and decompensated mode.
Floating BW (pin 8) or connecting it to V- internally compen-
sates the amplifier. In this mode, the MAX406 is unity-gain
stable with a 5V/ms typical slew rate and an 8kHz gain
bandwidth. Connecting BW to V+ puts the MAX406 into
decompensated mode with a 20V/ms typical slew rate and
a 40kHz gain bandwidth (AVCL 2 2VN).
The dual MAX407 and quad MAX418 are internally com-
pensated to be unity-gain stable. The MAX409/MAX417/
MAX419 single/dual/quad op amps feature 150kHz typical
bandwidth, 75V/ms slew rate, and stability for gains of
10VN or greater.
