SM72501

SolarMagic Precision, CMOS Input, RRIO, Wide Supply

Range Amplifier

General Description

Features

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.
