LMP7711/LMP7712  
Single and Dual Precision, 17 MHz, Low Noise, CMOS  
Input Amplifiers  
General Description  
Features  
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

n Space saving TSOT23 package (LMP7711)  
n MSOP-10 package (LMP7712)  
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 Applications  
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.  
n Active filters and buffers  
n Sensor interface applications  
n Transimpedance amplifiers  
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.
