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.
