Key Features
- Fixed gain of 10 with fully differential input and output eliminates external resistor networks and reduces gain-setting errors
- 60 dB typical common-mode rejection ratio (CMRR) and 55 dB minimum CMRR for robust noise rejection in mixed-signal designs
- 250 nA maximum input bias current minimizes loading effects on high-impedance signal sources
- Input offset voltage limited to 2500 µV max ensures accurate signal amplification in precision measurement chains
- Compact 8-pin MSOP package enables high-density placement on ADC front-end PCB layouts
Applications
The LTC1992-10 is used as a differential ADC driver in data acquisition systems where a fixed gain of 10 and high CMRR are required to reject common-mode noise on long cable runs. It also serves in precision instrumentation amplifier stages, motor current sensing circuits, and fully differential signal conditioning for 12-bit to 16-bit converters running from ±2.5V to ±5V rails.

Frequently Asked Questions
What gain does the LTC1992-10CMS8 provide and how does its fully differential topology benefit ADC driving?
The LTC1992-10 provides a fixed gain of 10 with a fully differential input and output structure, matching the input requirements of modern 12-bit and 16-bit successive-approximation ADCs. The differential topology delivers up to 60 dB CMRR, suppressing ground-loop noise and power-supply interference before the ADC sampling stage.
What is the input offset voltage specification of the LTC1992-10 and how does it affect measurement accuracy?
The LTC1992-10 specifies a maximum input offset voltage of 2500 µV. At a gain of 10, this translates to up to 25 mV of output offset, which must be accounted for in system calibration when driving 12-bit ADCs with a 2.5V full-scale input range to maintain sub-LSB accuracy.
Which supply voltage range does the LTC1992-10CMS8#PBF support and can it run from a single 5V rail?
The LTC1992-10 operates from a split supply of ±2.5V to ±5V or an equivalent single supply up to 10V total. Running from a single 5V rail is possible with proper input and output common-mode biasing at 2.5V, supporting battery-powered portable instruments and 5V industrial data acquisition boards.
How does the 8-pin MSOP package of the LTC1992-10 compare to an SO-8 footprint for PCB space savings?
The 8-pin MSOP package occupies approximately 4.9 mm × 3.0 mm versus roughly 4.9 mm × 3.9 mm for an SO-8, saving about 20% board area. This size advantage is significant in multi-channel ADC front-end boards where 8 or more differential amplifiers must fit within a constrained analog section.
