The MAX9613/MAX9615 are low-power precision op amps
with rail-to-rail inputs and rail-to-rail outputs. They feature
precision MOS inputs powered from an internal charge
pump to eliminate crossover distortion that is common
to complementary input-pair type amplifier architectures.
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 MAX9613/MAX9615 feature a self-calibration system
(on power-up), eliminating the effects of temperature and
power-supply variations.
The MAX9613/MAX9615 are capable of operating from a
1.7V to 5.5V supply voltage over the 0NC to +70NC tem-
perature range, and from 1.8V to 5.5V over the -40NC to
+125NC automotive temperature range.
Both singles and duals are available in tiny SC70 pack-
ages. The MAX9613 features a high-impedance output
while in shutdown.
