Description
The RE46C311/2 family of operational amplifiers (op
amps) from Microchip Technology Inc. operate with a
single-supply voltage as low as 1.8V, while drawing
less than 1 µA (maximum) of quiescent current per
amplifier. These devices are also designed to support
rail-to-rail input and output operation. This combination
of features supports battery-powered and portable
applications.
The RE46C311/2 amplifiers have a gain-bandwidth
product of 10 kHz (typical) and are unity gain stable.
These specifications make these op amps appropriate
for low-frequency applications, such as ionization
smoke detectors and sensor conditioning.
The RE46C311/2 family operational amplifiers are
offered in single (RE46C311), and dual (RE46C312)
configurations.
