What are the key features of LT1800CS8#PBF?
- 80 MHz gain-bandwidth product with rail-to-rail input and output swing enabling full-range signal processing from a single 2.7 V to 12.6 V supply
- 1.75 µA maximum bias current with 82 dB minimum CMRR, delivering precision DC accuracy in low-power sensor signal conditioning circuits
- Voltage-feedback architecture with internal frequency compensation in 8-pin SOIC package supporting drop-in replacement in standard op-amp footprints
What is LT1800CS8#PBF used for?
The LT1800CS8#PBF is well-suited for precision active filter designs, instrumentation front-ends, and photodiode transimpedance amplifiers where both rail-to-rail swing and 80 MHz bandwidth are required. Its low 1.75 µA bias current makes it ideal for high-impedance sensor interfaces such as pH electrodes and accelerometer signal conditioning in battery-powered portable instruments. Medical monitoring equipment and industrial data acquisition systems benefit from its 82 dB common-mode rejection ratio and precision voltage-feedback architecture.

Frequently Asked Questions
What gain-bandwidth product does LT1800CS8#PBF provide, and at what supply voltage is this 80 MHz figure specified?
The LT1800CS8#PBF is rated for an 80 MHz gain-bandwidth product, which is specified at a supply voltage of 5 V (±2.5 V). This wide bandwidth enables the amplifier to maintain unity-gain stability up to 80 MHz and provides useful closed-loop gain at frequencies up to 8 MHz when configured with a gain of 10 V/V. For lower-power designs operating at 2.7 V single supply, the bandwidth may derate slightly, so designers should consult the datasheet bandwidth vs. supply voltage curves.
How does the LT1800CS8#PBF's 1.75 µA bias current compare to standard BJT-input op-amps for high-impedance sensor interfaces?
The LT1800CS8#PBF has a maximum input bias current of 1.75 µA at 25°C, which is significantly higher than JFET-input op-amps that typically achieve bias currents below 10 pA. Compared to standard BJT-input op-amps which can have bias currents of 100 nA to 10 µA, the LT1800CS8 sits in a moderate range. For source impedances above 100 kΩ, the 1.75 µA bias current creates an offset voltage error of up to 175 mV, so JFET-input alternatives are preferred at very high source impedances above 1 MΩ.
What is the common-mode rejection ratio of LT1800CS8#PBF, and why does this matter in a differential signal conditioning design?
The LT1800CS8#PBF specifies a minimum CMRR of 82 dB and a typical CMRR of 105 dB. In differential signal conditioning, CMRR determines how well the amplifier rejects noise and interference that appears equally on both inputs, such as 50 Hz or 60 Hz mains hum in industrial environments. A 105 dB typical CMRR means common-mode noise is attenuated by a factor of approximately 178,000, which is sufficient for most precision measurement applications with millivolt-level signal differences on noisy power rails.
In what scenarios is LT1800CS8#PBF a better fit than the LT1801 dual-channel version for a compact PCB design?
Choose the LT1800CS8#PBF single-channel version in an 8-pin SOIC package when only one op-amp channel is needed and you want to minimize unused silicon area drawing idle supply current. The single-channel LT1800 consumes typically 4.5 mA supply current versus approximately 9 mA for the dual-channel LT1801, saving 4.5 mA in battery-powered designs. When two independent amplifier channels are required and PCB area is at a premium, the LT1801 dual in a single SOIC-8 package becomes the more efficient choice.
