LMP7701
Precision, CMOS Input, RRIO, Wide Supply Range
Amplifier
General Description
The LMP7701 is a single, low offset voltage, rail-to-rail input
and output precision amplifier with a CMOS input stage and
a wide supply voltage range. The LMP7701 is part of the
LMP
precision amplifier family and 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
±
10 pA make the LMP7701 ideal for precision applications.
The LMP7701 is built utilizing VIP50 technology, which al-
lows the combination of a CMOS input stage and a 12V
common mode and supply voltage range. This makes the
LMP7701 a great choice in many applications where con-
ventional CMOS parts cannot operate under the desired
voltage conditions.
The LMP7701 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 dif-
ference between the NMOS and PMOS offsets. The output
of the LMP7701 swings within 40 mV of either rail to maxi-
mize the signal dynamic range in applications requiring low
supply voltage.
The LMP7701 is offered in space saving SOT23-5. This
small package is an ideal solution for area constrained PC
boards and portable electronics.
