The MAX9636/MAX9637/MAX9638 are single-supply,
CMOS input op amps featuring wide bandwidth at low
quiescent current, making them suitable for a broad
range of battery-powered applications such as portable
medical instruments, portable media players, and smoke
detectors. A combination of extremely low input bias
currents, low input current noise and low input voltage
noise allows interface to high-impedance sources such
as photodiode and piezoelectric sensors. These devices
are also ideal for general-purpose signal processing
functions such as filtering and amplification in a broad
range of portable, battery-powered applications.
The ICs feature a maximized ratio of gain bandwidth
(GBW) to supply current. The devices operate from a
single 2.1V to 5.5V supply at a typical quiescent supply
current of 36µA. For additional power conservation, the
MAX9636 and MAX9638 offer a low-power shutdown
mode that reduces supply current to 1µA and places the
amplifiers’ outputs into a high-impedance state.
The ICs are specified over the automotive operating tem-
perature range (-40°C to +125°C). The single is offered
in a space-saving, 6-pin SC70 package, while the dual is
offered in tiny, 8-pin SC70 and 10-pin UTQFN packages.
