bias current precision amplifier. The ultra-low input  
bias current is 3 fA, with a specified limit of ±20 fA at  
25°C and ±900 fA at 85°C. This is achieved with the  
latest patent-pending technology of input bias current  
cancellation amplifier circuitry. This technology also  
maintains the ultra-low input bias current over the  
entire input common-mode voltage range of the  
amplifier.  
Input Bias Current (VCM = 1 V)  
Maximum at 25°C ±20 fA  
Maximum at 85°C ±900 fA  
Offset Voltage ±26 µV  
Offset Voltage Drift 1.5 μV/°C  
DC Open-Loop Gain 120 dB  
DC CMRR 100 dB  
Other outstanding features, such as low voltage noise  
(6.5 nV/Hz), low DC-offset voltage (±150 µV  
maximum at 25°C) and low-offset voltage  
temperature coefficient (1.5 µV/°C), improve system

applications. With a supply voltage range of 1.8 V to  
5.5 V, the LMP7721 is the ideal choice for battery-  
operated, portable applications. The LMP7721 is part  
of the LMP™ precision amplifier family.

As part of Texas Instruments' PowerWise™ products,  
the LMP7721 provides the remarkably wide-gain  
bandwidth product (GBW) of 17 MHz while  
consuming only 1.3 mA of current. This wide GBW  
along with the high open-loop gain of 120 dB enables

specifications, the LMP7721 has the performance to  
excel in a wide variety of applications such as

The LMP7721 is offered in an 8-pin SOIC package  
with a special pinout that isolates the amplifier’s input  
from the power supply and output pins. With proper  
board layout techniques, the unique pinout of the  
LMP7721 will prevent PCB leakage current from  
reaching the input pins. Thus system error will be  
further reduced.
