What are the key features of LT1997HMS-2#PBF?

  • 118 dB typical CMRR with 101 dB minimum, providing exceptional common-mode noise rejection for differential signal acquisition in high-interference environments
  • Wide supply voltage range difference amplifier with only 5 µA max bias current at 25 °C for minimal loading of high-impedance sources
  • Precision fixed-gain difference amplifier topology eliminates external resistor matching, ensuring consistent gain accuracy across production in measurement systems

What is LT1997HMS-2#PBF used for?

The LT1997HMS-2#PBF is designed for precision differential measurements in industrial current sensing, bridge transducer conditioning, and high-voltage motor phase-current monitoring where outstanding CMRR is essential to reject large common-mode swings. Its wide voltage range accommodates high-side current sensing on rails from low-voltage logic through high-voltage power-bus applications. The compact MSOP-8 package and internal precision resistor network reduce BOM complexity in test and measurement instruments demanding long-term gain stability.

Frequently Asked Questions

What CMRR does the LT1997HMS-2#PBF achieve, and why does that matter for high-side current sensing?

The LT1997HMS-2#PBF delivers a typical CMRR of 118 dB with a guaranteed minimum of 101 dB, meaning common-mode voltages are attenuated by at least 100,000:1 relative to the differential signal. In high-side current-sense circuits where the common-mode voltage can swing over tens of volts, this level of CMRR prevents common-mode interference from corrupting the millivolt-level differential signal across a shunt resistor.

What is the maximum input bias current of the LT1997HMS-2#PBF, and how does it influence shunt resistor selection?

The LT1997HMS-2#PBF has a maximum input bias current of 5 µA at 25 °C and up to 15 µA over temperature, which creates a small voltage error when multiplied by the shunt resistance. For a 10 mΩ shunt, the 15 µA maximum bias current produces a 0.15 µV offset error — negligible in most designs — but for larger impedance sense elements the bias error must be budgeted carefully.

Does the LT1997HMS-2#PBF require external frequency compensation, and what does that mean for board design?

No, the LT1997HMS-2#PBF does not require external frequency compensation components, simplifying board design by eliminating the compensation capacitors and resistors that externally compensated op-amps need. This reduces part count and board area while ensuring stable closed-loop behavior across the specified operating conditions without layout-dependent tuning.

Which package does the LT1997HMS-2#PBF use, and is it RoHS-compliant?

The LT1997HMS-2#PBF uses an MSOP-8 package (Analog Devices code 05-08-1847) measuring approximately 3 mm × 5 mm, suitable for compact PCB layouts in instrumentation and power-monitoring modules. The Pb-free code for this specific variant is listed as No, meaning this ordering part number is not a RoHS-compliant lead-free version; designers requiring RoHS compliance should select the equivalent #TRPBF lead-free variant.
