Description
The LMP7721MA/NOPB is a high-precision operational amplifier engineered for applications requiring exceptional sensitivity and accuracy. Featuring breakthrough input bias current cancellation technology, it achieves an ultra-low input bias current of 3fA (typical), with a specified limit of ±20fA at 25°C. As part of Texas Instruments’ PowerWise™ family, this amplifier provides a remarkably wide gain bandwidth product (GBW) of 17MHz while maintaining low power consumption, making it an ideal choice for high-impedance sensors and high-precision data acquisition systems.
Key Features
- Ultra-Low Bias Current: 3fA (typical) input bias current ensures minimal interference in high-impedance circuits.
- High Performance: 17MHz Gain Bandwidth Product (GBW) and 12.76V/µs slew rate for fast signal processing.
