2.3.2 LMP7704-SP

The LMP7704-SP is a precision amplifier with low input bias, low offset voltage, 2.5-MHz gain bandwidth product, and a wide supply voltage. The device is radiation hardened and operates in the military temperature range of −55°C to +125°C. The high DC precision of this amplifier, specifically the low offset voltage of ±60 µV and ultra-low input bias of ±500 fA, make this device an excellent choice for interfacing with precision sensors with high output impedance. This amplifier can be configured for transducer, bridge, strain gauge, and trans-impedance amplification.
