MIC864
Dual 350kHz Rail-to-Rail
Operational Amplifier
General Description
The MIC864 is a dual operational amplifier offering small-
size, low-power consumption (33µA/channel typical),
‘greater-than-the-rails’ input capability, and output range
to within 15mV of the supply rails. The MIC864 can be
operated with a single supply of +2.5V to +5.5V or a dual-
supply of ±1.25V to ±2.75V, and features an excellent
speed/power ratio with a gain bandwidth product of
350kHz.
The MIC864 was designed with input stage
transconductance normalization, making it immune to
common-mode rejection ratio (CMRR) and power supply
rejection ratio (PSRR) degradation across the input
voltage range. This feature makes the MIC864 superior to
some earlier operational amplifiers, in which a region of
the input voltage range was subject to degraded
performance.
The MIC864 is available with an industry standard pin
configuration in an 8-pin SOIC package, as well as a low
profile extra-thin (XTDFN) package and is specified to
operate from −40°C to +125°C junction temperature.
