LMP7715/LMP7716
Single and Dual Precision, 17 MHz, Low Noise, CMOS
Input Amplifiers
General Description
The LMP7715/LMP7716 are single and dual low noise, low
offset, CMOS input, rail-to-rail output precision amplifiers
with high gain bandwidth products. The LMP7715/LMP7716
are part of the LMPprecision amplifier family and are ideal
for a variety of instrumentation applications.
Utilizing a CMOS input stage, the LMP7715/LMP7716
achieve an input bias current of 100 fA, an input referred
voltage noise of 5.8 nV/
, and an input offset voltage of
less than ±150 µV. These features make the LMP7715/
LMP7716 superior choices for precision applications.
Consuming only 1.15 mA of supply current, the LMP7715
offers a high gain bandwidth product of 17 MHz, enabling
accurate amplification at high closed loop gains.
The LMP7715/LMP7716 have a supply voltage range of
1.8V to 5.5V, which makes these ideal choices for portable
low power applications with low supply voltage require-
ments.
The LMP7715/LMP7716 are built with National’s advanced
VIP50 process technology. The LMP7715 is offered in a
5-pin SOT23 package and the LMP7716 is offered in an
8-pin MSOP.
