Frequently Asked Questions
What common-mode rejection ratio does LTC1992-2HMS8#TRPBF achieve and how does it reduce noise in differential ADC driver circuits?
The LTC1992-2HMS8#TRPBF achieves a minimum 55 dB and typical 60 dB common-mode rejection ratio, attenuating power-line interference and ground noise by over 1000x at the differential output. This high CMRR ensures that a 16-bit or 18-bit ADC receives a clean balanced signal with minimal degradation from environmental noise sources in industrial data acquisition front ends.
When is a fixed gain of 2 differential amplifier like LTC1992-2HMS8 preferred over a programmable-gain amplifier in sensor interfaces?
A fixed gain of 2 is preferred when the sensor signal already spans 1 V to 2 V single-ended and needs to be scaled to match a differential ADC input range of 2 V to 4 V without added PGA complexity. The LTC1992-2HMS8 eliminates gain switching noise and code glitches, providing deterministic settling time below 1 µs, which is critical for fast-sampling industrial measurement systems.
How does the 2 nA bias current of LTC1992-2HMS8#TRPBF affect circuit design with high-impedance sources?
With an average bias current maximum of just 2 nA, the LTC1992-2HMS8#TRPBF draws negligible current from high-impedance sources such as pH electrodes, photodiodes with megaohm transimpedance resistors, or resistive bridge sensors. This low input current prevents voltage errors from developing across source impedances above 1 MOhm, allowing direct coupling without additional buffer stages in precision measurement circuits.
