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
, and an input offset voltage of
voltage noise of 5.8 nV/
less than
鹵
150 碌V. 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鈥檚 advanced
VIP50 process technology. The LMP7711 is offered in a
6-pin TSOT23 package and the LMP7712 is offered in a
10-pin MSOP.
