What are the key features of LT1990IS8-10#PBF?

  • 100 MHz bandwidth at gain of 10 supports wideband differential signal amplification for video, RF, and high-speed data acquisition systems
  • 72 dB typical CMRR (60 dB minimum) rejects common-mode noise across the full signal bandwidth for precision measurement in industrial environments
  • Fixed gain-of-10 architecture with precision internal resistors eliminates external gain-setting networks and trimming for consistent channel-to-channel matching

What is LT1990IS8-10#PBF used for?

The LT1990IS8-10#PBF is a wideband differential amplifier optimized for high-speed single-ended to differential conversion in data acquisition, motor drive feedback, and communication systems. Its 100 MHz bandwidth at gain of 10 supports signal conditioning for high-resolution ADC drivers and oscilloscope front-ends where both speed and common-mode rejection are critical. The compact SOIC-8 package integrates a complete precision gain-of-10 differential stage, reducing design complexity in PCB layouts for power monitoring and motor current sensing applications.

Frequently Asked Questions

How does the 100 MHz bandwidth of LT1990IS8-10#PBF support high-speed differential signal acquisition compared to lower-bandwidth alternatives?

At gain of 10, the LT1990IS8-10's 100 MHz bandwidth enables it to accurately amplify signals up to 10 MHz with less than 3 dB attenuation, compared to only 1 MHz for typical instrumentation amplifiers at similar gain. This makes it suitable for driving 14-bit ADCs sampling at 20 MSPS or higher in communications equipment and radar signal processing where signal fidelity above 1 MHz is essential.

What CMRR does LT1990IS8-10#PBF provide, and how does this affect motor current measurement accuracy in the presence of switching noise?

The LT1990IS8-10 provides 72 dB typical CMRR, rejecting common-mode interference by a factor of approximately 4000x. In motor drive applications where switching transients generate 10 V of common-mode noise on the shunt sense lines, the 72 dB CMRR reduces this interference to less than 2.5 mV at the amplifier output, enabling current measurement accuracy better than 0.5% over a 1 A to 20 A range.

When is the fixed gain-of-10 in LT1990IS8-10#PBF advantageous compared to a variable-gain instrumentation amplifier like INA128?

The LT1990IS8-10's internal precision resistor network provides gain-of-10 with better than 0.1% gain accuracy and no external resistors, avoiding the 0.1% to 1% gain error introduced by external 1% tolerance resistors in INA128-based designs. For fixed-gain channels in motor control, power monitoring, or sensor conditioning where reconfigurability is not needed, the LT1990IS8-10 saves board area by eliminating 2 gain-setting resistors per channel while achieving 100 MHz bandwidth unmatched by most instrumentation amplifiers at this gain.

What is the input offset voltage of LT1990IS8-10#PBF and how does it affect measurement accuracy in a 5 V full-scale differential sensing system?

The LT1990IS8-10 specifies a maximum input offset voltage of 4500 µV (4.5 mV). At gain of 10, this appears as 45 mV of output offset error, representing 0.9% of a 5 V full-scale output range. For 12-bit ADC systems requiring better than 0.1% accuracy, designers should apply a digital offset calibration step during production test or use a higher-precision companion ADC channel to subtract the known offset contribution across the operating temperature range of -40°C to 85°C.
