SM72501 Datasheet | National Semiconductor

Description The SM72501 is a low offset voltage, rail-to-rail input and output precision amplifier with a CMOS input stage and a wide supply voltage range. The SM72501 is ideal for sensor interface 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 p A makes the SM72501 ideal for precision applications. The SM72501 is built utilizing VIP50 technology, which allows the bination of a CMOS input stage and a 12V mon 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 monly associated with rail-torail input amplifiers. This is achieved by trimming both sides of the plimentary input stage, thereby reducing the difference between the NMOS and PMOS offsets. The output of the SM72501 swings within 40 m V 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.
