DESCRIPTION
The SM73308 is a single low noise precision
operational amplifier intended for use in a wide range
of applications. Other important characteristics
include: an extended operating temperature range of
−40°C to 125°C, the tiny SC70-5 package, and low
input bias current.
The extended temperature range of −40°C to 125°C
allows the SM73308 to accommodate a broad range
of applications. The SM73308 expands TI’s Silicon
Dust™ amplifier portfolio offering enhancements in
size, speed, and power savings. The SM73308 is
ensured to operate over the voltage range of 2.7V to
5.0V and has rail-to-rail output.
The SM73308 is designed for precision, low noise,
low voltage, and miniature systems. This amplifier
provides rail-to-rail output swing into heavy loads.
The maximum input offset is 850 μV at room
temperature and the input common mode voltage
range includes ground.
The SM73308 is offered in the tiny SC70-5 package.
