LMP7721MA/NOPB Product Details

The LMP7721MA/NOPB is the industry’s lowest specified input 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.

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 sensitivity and accuracy in high-precision applications. With a supply voltage range of 1.8 V to 5.5 V, the LMP7721MA/NOPB is the ideal choice for battery-operated, portable applications. The LMP7721MA/NOPB is part of the LMP precision amplifier family.

As part of Texas Instruments’ PowerWise? products, the LMP7721MA/NOPB 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 accurate signal conditioning. With these specifications, the LMP7721MA/NOPB has the performance to excel in a wide variety of applications such as electrochemical cell amplifiers and sensor interface circuits.

The LMP7721MA/NOPB 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 LMP7721MA/NOPB will prevent PCB leakage current from reaching the input pins. Thus system error will be further reduced.
