MP8101
Ultra Low Power
1.8V, 400KHz Op Amp
The Future of Analog IC Technology
DESCRIPTION
FEATURES
The MP8101 is a rail-to-rail output, operational
amplifier in a TSOT-23 package. This amplifier
provides 400KHz bandwidth while consuming
an incredibly low 11µA of supply current. The
MP8101 can operate with a single supply
voltage as low as 1.8V.

and all capacitors should be low ESL
(Equivalent Series Inductance) and low ESR
APPLICATION INFORMATION
Power Supply Bypassing
Regular supply bypassing techniques are
recommended. A 10µF capacitor in parallel with
a 0.1µF capacitor on both the positive and
negative supplies is ideal. For the best
performance, all bypassing capacitors should
(Equivalent Series Resistance). Surface mount
ceramic
capacitors
are
ideal
