FEATURES  
DESCRIPTION  
The LMP7707/LMP7708/LMP7709 devices are  
single, dual, and quad low offset voltage, rail-to-rail  
input and output precision amplifiers which each have  
a CMOS input stage and a wide supply voltage  
range. The LMP7707/LMP7708/LMP7709 are part of  
the LMP™ precision amplifier family and are ideal for  
23  
Unless Otherwise Noted, Typical Values at  
VS = 5V.  
Input Offset Voltage (LMP7707) ±200 µV (Max)

Input Bias Current ±200 fA  
applications. These decompensated amplifiers are  
stable at a gain of 6 and higher.  
Input Voltage Noise 9 nV/Hz  
CMRR 130 dB  
The ensured low offset voltage of less than ±200 µV  
along with the ensured low input bias current of less  
than ±1 pA make the LMP7707/LMP7708/LMP7709  
Open Loop Gain 130 dB  
Temperature Range 40°C to 125°C  
Gain Bandwidth Product (AV =10) 14 MHz  
Stable at a Gain of 10 or Higher  
Supply Current (LMP7707) 715 µA  
Supply Current (LMP7708) 1.5 mA  
Supply Current (LMP7709) 2.9 mA  
Supply Voltage Range 2.7V to 12V

for  
precision  
applications.  
The  
LMP7707/LMP7708/LMP7709 are built utilizing VIP50  
technology, which allows the combination of a CMOS  
input stage and a supply voltage range of 12V with  
rail-to-rail common mode voltage capability. The  
LMP7707/LMP7708/LMP7709 are the perfect choice  
in many applications where conventional CMOS parts  
cannot operate due to the voltage conditions.  
The unique design of the rail-to-rail input stage of  
each  
of  
the  
LMP7707/LMP7708/LMP7709  
APPLICATIONS  
significantly reduces the CMRR glitch commonly  
associated with rail-to-rail input amplifiers. Both sides  
of the complimentary input stage have been trimmed,  
thereby reducing the difference between the NMOS  
and PMOS offsets. The output swings within 40 mV  
of either rail to maximize the signal dynamic range in  
applications requiring low supply voltage.

The LMP7707 is offered in the space-saving 5-pin  
SOT-23 and 8-pin SOIC packages, the LMP7708 is  
offered in the 8-pin VSSOP and 8-pin SOIC  
packages, and the quad LMP7709 is offered in the  
14-pin TSSOP and 14-pin SOIC packages. These  
small packages are ideal solutions for area  
constrained PC boards and portable electronics.
