Frequently Asked Questions
What is the typical common-mode rejection ratio of the LT1997HMS-1#PBF, and why is it important for differential measurements?
The LT1997HMS-1#PBF achieves a typical CMRR of 98dB, with a minimum specification of 84dB. High CMRR is essential in differential amplifier applications because it determines how well the device rejects noise and interference common to both inputs, such as 50Hz/60Hz line noise or high-voltage common-mode signals in motor drives and industrial current sensing applications.
How does the LT1997HMS-1#PBF's ultra-low bias current benefit high-impedance sensor circuits?
With a maximum bias current of 0.015µA and a typical value of only 0.005µA at 25°C, the LT1997HMS-1#PBF introduces minimal loading error on high-impedance sources such as Wheatstone bridges or resistive sensors. In a 10kΩ source impedance circuit, this bias current causes less than 0.15mV of offset, enabling accurate signal acquisition without buffering requirements.
In which precision measurement scenarios is LT1997HMS-1#PBF preferred over a standard op-amp difference circuit?
The LT1997HMS-1#PBF is preferred when the common-mode voltage exceeds the amplifier supply rail or when matched resistor networks in discrete difference circuits would degrade CMRR over temperature. Its integrated precision resistor network maintains 98dB CMRR without external trimming, making it ideal for 4-20mA loop receivers, high-side current sensing, and precision bridge amplifiers operating over -40°C to +125°C.
