LMP7721MA Product Details
The LMP7721MA 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 is the ideal choice for battery-operated, portable applications. The LMP7721MA is part of the LMP precision amplifier family.
As part of Texas Instruments’ PowerWise products, the LMP7721MA 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 has the performance to excel in a wide variety of applications such as electrochemical cell amplifiers and sensor interface circuits.
The LMP7721MA 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 will prevent PCB leakage current from reaching the input pins. Thus system error will be further reduced.
