a wide supply voltage range. The LMP7701 is part of the
鈩?/div>
precision amplifier family and is ideal for sensor
interface and other instrumentation applications.
The guaranteed low offset voltage of less than
鹵
200 碌V
along with the guaranteed low input bias current of less than
鹵
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.
