What are the key features of LTC1992-10IMS8#PBF?
- Fixed gain-of-10 fully differential in/out amplifier with 2 pA input bias current for ultra-high-impedance signal sources
- 60 dB common-mode rejection ratio with frequency compensation for driving high-speed differential ADC inputs with minimal distortion
- Compact MSOP-8 package with voltage-feedback architecture enabling precise single-supply differential signal conditioning in space-constrained designs
What is LTC1992-10IMS8#PBF used for?
The LTC1992-10IMS8#PBF is engineered for driving fully differential ADC inputs in high-speed data acquisition systems, where a fixed gain of 10 amplifies low-level differential sensor signals while rejecting common-mode noise. It is ideal for precision measurement instruments, communications test equipment, and industrial data converters requiring low input bias current from high-impedance bridge or differential sensor sources. The fully differential output directly interfaces with 12-bit to 16-bit pipeline ADCs in single-supply systems, reducing external component count compared to two single-ended op-amps.

Frequently Asked Questions
How does the LTC1992-10's fixed gain-of-10 architecture simplify driving a 16-bit differential ADC compared to using two discrete op-amps?
The LTC1992-10 integrates a fully differential gain-of-10 amplifier in a single MSOP-8 package, directly driving a 16-bit ADC's differential input pair without requiring a separate anti-aliasing filter design or resistor gain networks that introduce 0.1% matching errors. With 2 pA input bias current and 60 dB CMRR, the device amplifies a 100 mV differential sensor signal to 1 V peak-to-peak while rejecting 200 mV of common-mode supply noise. Compared to two discrete op-amps in SOIC-8 packages, the LTC1992-10 halves the PCB area and eliminates 4 gain-setting resistors from the BOM.
For a precision strain gauge bridge amplifier, what does the LTC1992-10's 2500 µV offset and 60 dB CMRR mean for measurement accuracy?
With a maximum input offset voltage of 2500 µV referred to the input and gain of 10, the LTC1992-10 introduces a referred-to-output error of 25 mV, which corresponds to approximately 0.025% full-scale error on a 10 V output range and may require offset nulling for 16-bit accuracy. The 60 dB CMRR rejects common-mode interference by 1000:1, reducing a 100 mV powerline-induced common-mode disturbance at the bridge output to only 100 µV of differential error. For strain gauge bridges with 2 mV/V sensitivity on 5 V excitation, the device resolves signals down to approximately 10 µV/µε with adequate noise performance.
When is the LTC1992-10IMS8#PBF preferred over a variable-gain instrumentation amplifier for an industrial data acquisition front-end?
The LTC1992-10IMS8#PBF is preferred when the gain is always fixed at 10 and the design needs to minimize component count, since a fixed-gain topology avoids the 3 external resistors and matching requirements of variable-gain instrumentation amplifiers, reducing assembly defect risk at 500-unit production volumes. For industrial 4-20 mA current loop receivers converting a 1 V to 5 V differential signal to a 10 V to 50 V output range, the fixed gain-of-10 eliminates the gain calibration step in production test, saving approximately 30 seconds per unit. The 2 pA bias current makes it superior to bipolar instrumentation amplifiers for source impedances above 100 kΩ where bias-current-induced offset would exceed 200 µV.
