The SIM910 and SIM911 are low-noise, programmable preamplifiers which are ideal for a wide range of small signal applications. The primary differences between the two models are their input impedance and input noise. The SIM911 has a bipolar junction transistor front-end, offers lower input noise, and has a 100 kW front-end impedance. The low bias current and 100 MW input impedance of the SIM910, which has a JFET front-end, make it a better choice for use with high impedance sources.
