DESCRIPTION
FEATURES
The MP8102 is a rail-to-rail output, operational
amplifier in a TSOT-23 package. This amplifier
provides 600KHz bandwidth while consuming
an incredibly low 7.5µA of supply current. The
MP8102 can operate with a single supply
voltage as low as 1.8V.

Notes: Close S3 for positive gain. Input signal to RF(+Av) connector.
The gain Av = 1 + RFB/RIN.
For unity gain, remove RIN and short RFB.
Open S3 for negative gain. Input signal to RF(-Av) connector.
The gain Av = -RFB/RIN.
S1 and S2 are switches for possible resistor and capacitor load

performance, all bypassing capacitors should
be located as close to the op amp as possible
and all capacitors should be low ESL
(Equivalent Series Inductance) and low ESR
(Equivalent Series Resistance). Surface mount
ceramic capacitors are ideal.
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
