What are the key features of XOPA818IDRGT?
- 2.7 GHz gain-bandwidth product enabling high-speed signal amplification in RF and instrumentation circuits
- FET input stage with 0.5 nA maximum bias current for accurate high-impedance source amplification
- Decompensated architecture stable at 7 V/V minimum gain, optimizing bandwidth at moderate closed-loop gain
- 90 dB typical CMRR suppressing common-mode interference in differential signal chains
What is XOPA818IDRGT used for?
XOPA818IDRGT is used in high-speed transimpedance amplifiers, photodetector front-ends, and RF signal conditioning circuits where wide bandwidth and low input bias current are simultaneously required. The decompensated 7 V/V minimum stable gain allows designers to achieve multi-GHz closed-loop bandwidth with gains between 7 V/V and higher. It also suits active filter and fast comparator replacement applications in precision instrumentation at 13 V supply.

Frequently Asked Questions
What gain-bandwidth product does XOPA818IDRGT offer and at what minimum closed-loop gain is it stable?
XOPA818IDRGT has a gain-bandwidth product of 2.7 GHz and is a decompensated amplifier stable at a minimum closed-loop gain of 7 V/V. At a gain of 10 V/V, the amplifier provides approximately 270 MHz of closed-loop bandwidth, which is ideal for high-speed instrumentation and signal chain applications.
How does the FET input of XOPA818IDRGT make it suitable for high-impedance sensor interfaces?
The FET input stage of XOPA818IDRGT limits bias current to a maximum of 0.5 nA (0.0005 µA), which minimizes voltage error when driving from high-impedance sources such as photodiodes, pH electrodes, or capacitive sensors. By contrast, bipolar-input op-amps can exhibit bias currents 100 times higher, causing significant offset at multi-megaohm source impedances.
In a 13 V single-supply system, how does the 90 dB CMRR of XOPA818IDRGT help in differential measurement designs?
With a typical CMRR of 90 dB, XOPA818IDRGT rejects common-mode noise at 90 dB below the differential signal, allowing very small differential signals of a few millivolts to be accurately amplified even in the presence of 50 Hz or 60 Hz mains interference. This makes it valuable in industrial sensor amplifiers, medical ECG front-ends, and communication line receivers powered from a 13 V supply.
