What are the key features of LT1672CS8#PBF?
- Rail-to-rail input and output swing maximizing usable signal range on low-voltage supplies
- 98 dB minimum CMRR (120 dB typical) for exceptional differential signal accuracy
- Ultra-low 1 nA input bias current enabling connection to high-impedance sensors
- 2 µA quiescent supply current ideal for battery-powered precision instruments
- Precision voltage-feedback architecture with minimum gain of 5 for stable closed-loop use
What is LT1672CS8#PBF used for?
The LT1672CS8#PBF is designed for precision battery-powered instrumentation, portable medical diagnostics, and sensor signal conditioning where ultra-low bias current and rail-to-rail swing are critical. Its 98 dB CMRR and 1 nA input bias current make it suitable for electrochemical sensor interfaces, pH meters, and photodiode transimpedance amplifiers requiring minimal input loading. Data acquisition systems, precision voltage references, and low-power IoT analog front ends also benefit from its combination of low supply current and high common-mode rejection.

Frequently Asked Questions
How does the 1 nA input bias current of LT1672CS8#PBF benefit high-impedance electrochemical sensor interfaces?
At 1 nA maximum input bias current, the LT1672CS8#PBF introduces less than 1 mV of error when driving from a 1 MΩ source impedance, making it suitable for pH electrodes, ion-selective sensors, and photodiodes that present source impedances from 10 MΩ to over 1 GΩ without needing additional buffer stages.
For a 3 V single-supply portable instrument, what rail-to-rail output swing does LT1672CS8#PBF provide?
The rail-to-rail output stage of LT1672CS8#PBF swings to within a few millivolts of both the positive and negative supply rails on a 3 V supply, effectively providing nearly 3 V of output dynamic range. This maximizes ADC utilization and avoids the signal headroom loss typical of conventional op-amps on low-voltage supplies.
What minimum closed-loop gain is specified for LT1672CS8#PBF and why does it matter in circuit design?
The LT1672CS8#PBF specifies a minimum stable closed-loop gain of 5 (14 dB). Designers must configure feedback networks to maintain at least this gain level; operating below Av=5 risks oscillation due to the absence of internal frequency compensation. This constraint must be observed in all inverting and non-inverting amplifier topologies using this device.
How does the 98 dB minimum CMRR of LT1672CS8#PBF compare to standard op-amps in a bridge sensor application?
A 98 dB minimum CMRR means common-mode interference is attenuated by over 63,000 times, far exceeding the 70 dB typical of general-purpose op-amps. In a Wheatstone bridge sensor application with 1 V of common-mode supply noise, the LT1672CS8#PBF limits common-mode error at the output to below 16 µV, compared to 316 µV for a 70 dB device.
