General Description
The SM72501 is a low offset voltage, rail-to-rail input and out-
put precision amplifier with a CMOS input stage and a wide
supply voltage range. The SM72501 is ideal for sensor inter-
face and other instrumentation applications.
The guaranteed low offset voltage of less than ±200 µV along
with the guaranteed low input bias current of less than ±1 pA
makes the SM72501 ideal for precision applications. The
SM72501 is built utilizing VIP50 technology, which allows the
combination of a CMOS input stage and a 12V common mode
and supply voltage range. This makes the SM72501 a great
choice in many applications where conventional CMOS parts
cannot operate under the desired voltage conditions.
The SM72501 has a rail-to-rail input stage that significantly
reduces the CMRR glitch commonly associated with rail-to-
rail input amplifiers. This is achieved by trimming both sides
of the complimentary input stage, thereby reducing the differ-
ence between the NMOS and PMOS offsets. The output of
the SM72501 swings within 40 mV of either rail to maximize
the signal dynamic range in applications requiring low supply
voltage.
The SM72501 is offered in the space saving 5-Pin SOT23.
This small package is an ideal solution for area constrained
PC boards and portable electronics.
