The MAX9614/MAX9616 are low-power precision op
amps that feature precision MOS inputs.
These devices are ideal for a large number of signal pro-
cessing applications such as photodiode transimped-
ance amplifiers and filtering/amplification of a wide
variety of signals in industrial equipment. The devices
also feature excellent RF immunity, making them ideal for
portable applications.
The MAX9614/MAX9616 are capable of operating from
a 2.5V to 5.5V supply voltage over the -40NC to +125NC
automotive temperature range.
Both singles and duals are available in tiny SC70 pack-
ages. The MAX9614 features an active-low shutdown pin.
