LMP7715/LMP7716/
LMP7716Q
October 20, 2009
Single and Dual Precision, 17 MHz, Low Noise, CMOS Input
Amplifiers
General Description
The LMP7715/LMP7716/LMP7716Q are single and dual low
noise, low offset, CMOS input, rail-to-rail output precision am-
plifiers with high gain bandwidth products. The LMP7715/
LMP7716/LMP7716Q are part of the LMP
®
precision amplifier
family and are ideal for a variety of instrumentation applica-
tions.
Utilizing a CMOS input stage, the LMP7715/LMP7716/LM-
P7716Q achieve an input bias current of 100 fA, an input
referred voltage noise of 5.8 nV/
, and an input offset volt-
age of less than ±150 μV. These features make the LMP7715/
LMP7716/LMP7716Q superior choices for precision applica-
tions.
Consuming only 1.15 mA of supply current, the LMP7715 of-
fers a high gain bandwidth product of 17 MHz, enabling
accurate amplification at high closed loop gains.
The LMP7715/LMP7716/LMP7716Q 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 re-
quirements.
The LMP7715/LMP7716/LMP7716Q are built with National’s
advanced VIP50 process technology. The LMP7715 is of-
fered in a 5-pin SOT-23 package and the LMP7716/LM-
P7716Q is offered in an 8-pin MSOP.
The LMP7716Q incorporates enhanced manufacturing and
support processes for the automotive market, including defect
detection methodologies. Reliability qualification is compliant
with the requirements and temperature grades defined in the
AEC-Q100 standard.
