low-input bias current operational amplifiers offering rail-
to-rail outputs and single-supply operation down to 2.7V.
They draw 2.2mA of quiescent supply current per amplifier
when enabled. Ultra-low distortion (0.0002% THD+N), as
well as low input voltage-noise density (4.2nV/√Hz)
and
low input current-noise density (0.5fA/√Hz).
The low input
bias current and low noise together with the wide bandwidth
will suit transimpedance amplifiers and imaging applications.
For power conservation, the MAX40075/MAX40088 offer
a low-power shutdown mode that reduces supply current
to 0.1μA and places the amplifiers outputs into a high
impedance state. These amplifiers have outputs which
swing rail-to-rail and their input common-mode voltage
range includes ground. The MAX40075 is unity-gain
stable with a gain-bandwidth product of 10MHz. The
MAX40088 is gain-of-5 stable with a gain-bandwidth
product of 42MHz.
