Key Features
- 90 MHz gain-bandwidth product with 2200 V/µs slew rate enables high-speed signal conditioning in ADC drivers and active filter stages
- 0.5 µA input bias current at 25°C and 110 dB CMRR deliver precision performance in instrumentation amplifier front-ends and sensor interfaces
- Low-power dual-channel design in a compact MSOP-8 footprint reduces power budget and board space in portable and battery-operated measurement equipment
Applications
The LT6275IMS8#PBF is suited for high-speed data acquisition signal chains where a 90 MHz bandwidth and 2200 V/µs slew rate are required ahead of 12-bit to 16-bit ADCs in industrial instruments and communications equipment. Its low 0.5 µA input bias current and 110 dB CMRR make it an excellent choice for precision differential amplifier stages in medical monitoring devices, sensor signal conditioners, and active filter networks. The dual-channel MSOP-8 configuration saves board space in designs that need two matched amplifier paths for differential or stereo processing.

Frequently Asked Questions
How does the 2200 V/µs slew rate of the LT6275IMS8#PBF compare to general-purpose op-amps for driving a 14-bit ADC input?
A 2200 V/µs slew rate allows the LT6275IMS8#PBF to settle a 2 V full-scale step in well under 1 µs, far exceeding the settling requirement of most 14-bit ADCs with throughput rates up to 10 MSPS. In comparison, a general-purpose op-amp with 10 V/µs would require approximately 200 ns per 2 V swing, introducing distortion at sample rates above 1 MSPS.
What CMRR specification does the LT6275IMS8#PBF offer, and why does it matter in differential sensor interfaces?
The LT6275IMS8#PBF achieves a typical CMRR of 110 dB and a minimum of 90 dB, meaning common-mode noise up to 1 V is attenuated to below 3 µV at the output. This level of rejection is critical in industrial sensor interfaces where 50 Hz or 60 Hz mains interference and ground differentials can reach several hundred millivolts.
For a portable medical instrument powered by dual AA batteries, can the LT6275IMS8#PBF operate at the available supply voltage?
The LT6275IMS8#PBF operates from supply voltages ranging from a total of 2.5 V up to 30 V (single supply), which is compatible with 2× AA alkaline cells providing approximately 3 V when fresh. Its low quiescent current further extends battery life, making it well suited for handheld ECG monitors or portable biosignal acquisition front-ends.
How compact is the MSOP-8 package of the LT6275IMS8#PBF, and what PCB design rules apply?
The MSOP-8 package measures approximately 3.0 mm × 3.0 mm with a 0.65 mm pin pitch, providing a dual-amplifier solution in a footprint nearly half the area of a standard SOIC-8. PCB designers should use 100 nF bypass capacitors at each supply pin routed within 1 mm of the package, and ensure power and signal ground planes are separated to preserve the 110 dB CMRR at high frequencies.
