LMP7711/LMP7712
Single and Dual Precision, 17 MHz, Low Noise, CMOS
Input Amplifiers
General Description
The LMP7711/LMP7712 are single and dual low noise, low
offset, CMOS input, rail-to-rail output precision amplifiers
with a high gain bandwidth product and an enable pin. The
LMP7711/LMP7712 are part of the LMP™ precision amplifier
family and are ideal for a variety of instrumentation applica-
tions.
Utilizing a CMOS input stage, the LMP7711/LMP7712
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 LMP7711/
LMP7712 superior choices for precision applications.
Consuming only 1.15 mA of supply current, the LMP7711
offers a high gain bandwidth product of 17 MHz, enabling
accurate amplification at high closed loop gains.
The LMP7711/LMP7712 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. In order to reduce the already low power consump-
tion the LMP7711/LMP7712 have an enable function. Once
in shutdown, the LMP7711/LMP7712 draw only 140 nA of
supply current.
The LMP7711/LMP7712 are built with National’s advanced
VIP50 process technology. The LMP7711 is offered in a
6-pin TSOT23 package and the LMP7712 is offered in a
10-pin MSOP.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test conditions, see the Electrical Characteristics Tables.
Note 2: Human Body Model is 1.5 kΩ in series with 100 pF. Machine Model is 0Ω in series with 200 pF.
Note 3: The maximum power dissipation is a function of TJ(MAX), θJA. The maximum allowable power dissipation at any ambient temperature is
PD = (TJ(MAX) - TA)/θJA. All numbers apply for packages soldered directly onto a PC Board.
Note 4: Typical values represent the most likely parametric norm at the time of characterization.
Note 5: Limits are 100% production tested at 25˚C. Limits over the operating temperature range are guaranteed through correlations using the Statistical Quality
Control (SQC) method.
Note 6: Offset voltage average drift is determined by dividing the change in VOS at the temperature extremes by the total temperature change.
Note 7: Positive current corresponds to current flowing into the device.
Note 8: Guaranteed by design.
Note 9: The short circuit test is a momentary open loop test.
