Key Features
- Fixed gain of 2 with fully differential input and output, ideal for driving ADC inputs without external resistors
- 60 dB typical common-mode rejection ratio with 55 dB minimum, suppressing noise in high-precision signal chains
- Ultra-low bias current of 2 nA maximum enables accurate operation with high-impedance source signals
Applications
The LTC1992-2IMS8#TRPBF is designed for precision differential signal conditioning, especially for driving the differential inputs of high-resolution ADCs in data acquisition systems. Its fixed gain of 2 and excellent CMRR make it effective in industrial instrumentation, medical diagnostics, and communication equipment where single-ended to differential conversion is required. The compact MSOP-8 package suits space-constrained PCB layouts in test and measurement equipment.

Frequently Asked Questions
How does the fixed gain-of-2 architecture of LTC1992-2IMS8#TRPBF simplify ADC driver design compared to discrete op-amp circuits?
By integrating a precision gain-of-2 stage with matched internal resistors, the LTC1992-2 eliminates the need for external gain-setting resistors, reducing component count by 4 or more parts per channel. Its 60 dB CMRR ensures common-mode noise rejection better than 1 mV of differential error at the ADC input, simplifying board layout and calibration.
What common-mode rejection ratio does LTC1992-2IMS8#TRPBF provide, and why does this matter in industrial sensor interfaces?
The LTC1992-2 guarantees a minimum CMRR of 55 dB and typically achieves 60 dB, meaning it attenuates common-mode interference such as 50 Hz power-line noise by a factor of at least 316x. In 4 to 20 mA industrial loops or thermocouple inputs, this keeps differential measurement error below 2.5 mV even in noisy environments.
What is the input offset voltage specification for LTC1992-2IMS8#TRPBF and how does it impact measurement accuracy?
The LTC1992-2 specifies a maximum input offset voltage of 2500 µV. For a gain-of-2 configuration, this offset appears as up to 5 mV of error at the output, which designers must budget in 12-bit ADC systems to avoid losing more than 1 to 2 LSBs of resolution at full-scale ranges below 2 V.
Which package does LTC1992-2IMS8#TRPBF use and how does its footprint compare to standard SOIC-8 packages?
The LTC1992-2IMS8 is housed in an MSOP-8 package, which occupies approximately 3 mm x 3 mm, roughly 60% less board area than a standard SOIC-8 footprint of about 5 mm x 4 mm. This compactness benefits portable instrumentation and multi-channel data acquisition boards where channel density per square centimeter is critical.
