LTC2387 Drivers Part III: Trans-Impedance Amplifier/Driver

Derek Redmayne - Staff Scientist Sep 8th 2016
This is unabashedly a classic case of what marketing calls “a solution looking for a problem”. It is an example of how the full SNR of the LTC2387 may be realized for a real world signal. Most signals originating in low level circuitry, in sensors, or in the real world, will require significant gain to develop 8Vp-p ...

Avoid Amplifier Output Driver Saturation When Using pA Bias Current Amplifiers with High Source Impedance Sensors

Jon Munson - Applications Engineer
Kevin B. Scott - Senior Strategic Marketing Engineer Mar 26th 2015
Need for Low Bias Current Amplfiers When taking sensor measurements, the type of sensor excitation used varies greatly; it can be a DC signal, an AC signal, a voltage source, a current source or a pulsed source to name a few. When using current source excitation or when using a high impedance sensor, the amplifier's bias current ...

Transimpedance Amplifier Noise Considerations

Feb 18th 2015
The LTC6268 and LTC6269 is a single/dual 500MHz FET-input operational amplifier with extremely low input bias current and low input capacitance. It also features low input referred current noise and voltage noise making it an ideal choice for high speed transimpedance amplifiers, CCD output buffers, and high-impedance ...
