The best I have found was a forum thread at DIYaudio, but the recommendations tended to be old-school, even obsolete parts. However, it has been experienced that diffusion noise in a large variety of pn diodes (transistors) can deviate from the expected value given by the Schottky theorem or by the Van der Ziel representation commo. Select between three different revisions: Rev. "The LSK389, Ultra-Low Noise, Monolithic Dual, N-Channel JFET provides designers with a better-performing solution for obtaining tighter IDSS matching and better thermal tracking than using individual JFETs or non-monolithic dual JFETs," Linear Systems President Tim McCune says. The all-new J. High performance models are available with noise temperatures. 47 - 1218 MHz, 75 Ohm, 25 dB CATV Amplifier. The features of ultra low noise, low operating voltage, and low saturation voltage are suitable for microphone amplifier of digital audio items such as portable MD,DAT,and others. All resistors are metal film to help keeping noise low. Hz) for very high input impedance rather than ultra low noise. The LT1128 is an ultra-low-noise, high-speed op-amp. The circuit has. It is very suitable for extremely low level audio applications as in audio preamplifiers. LSJ74 datasheet, LSJ74 PDF, LSJ74 Pinout, Equivalent, Replacement - ULTRA LOW NOISE SINGLE P-CHANNEL JFET - Linear Integrated Systems, Schematic, Circuit, Manual. LINEAR INTEGRATED SYSTEMS ANNOUNCES ULTRA LOW NOISE P-CHANNEL DUAL JFET: FREMONT, CALIFORNIA - June 1, 2016 - Linear Integrated Systems (LIS), a leading full-service manufacturer of specialty linear semiconductors, announces the immediate availability of its LSJ689, a 1. Focal ® is a Focal-JMlab brand- Tel (33) (0)4 77 43 57 00 - www. The regulator circuitry is based on Stax patented shunt topology( see below). noise figure possible. The part is an ideal combination of high transconductance, ultra-low noise and relatively low input capacitance. Require ultra-low noise piezoelectric sensors and dedicated electronics to preserve Signal-to-Noise Ratio. It is not only an interruption, but is also a disruption of thought”. This latest addition to the LIS family of Ultra-Low-Noise JFETs provides users with many more design options than available by using only N-Channel JFETs. In response to the need of an ultra low noise preamplifier, a very low noise single-transistor common-source JFET amplifier is used as the main amplification stage. compressors, overdrives and distortions) along the signal path will amplify any noise present in that stage. 5 dB typical at 12 GHz and a robust Power In (Pin) of up to 20dBm.
