Signal Conditioning Circuit for KMI 15/x Rotation Speed Sensor
A modulated current is supplied by the integrated rotational speed sensor KMI 15/x. This current signal needs to be converted into a ground-referenced voltage signal.
The KMI 15/x sensor operates by generating a modulated current proportional to the rotational speed of...
For low-noise amplifier OP amplifier RIAA compensation
A common telecoil follows the MM formula (magnetic-acting) and has an impedance of approximately 600 ohms to effectively receive signals. It is necessary to reduce the impedance in the high-frequency segment, which is achieved by placing a 150pF capacitor in...
Low-noise broadband amplifier
The amplifier delivers a gain of 10 dB across a frequency range of 10-600 MHz and features a 1-to-1 impedance match at 50 ohms. The BFR91 transistor exhibits a noise figure of 1 dB at 500 MHz. The circuit operates...
Low-power-inverter
This low-power inverter utilizes only nine components to convert 10 to 16 VDC into a 60 Hz, 115 V square-wave output suitable for operating AC equipment with a maximum power of 25 W. The initial section of the 556 timer...
Low-Noise Audio Preamp
A low-noise LT1115 (Linear Technology, Inc.) operational amplifier is connected to a class-A buffer amplifier to create a variable gain (12-to-50 dB) microphone preamplifier. Total harmonic distortion (THD) is less than 0.01% across a frequency range from 80 Hz to...
Low-Power Amplifier with digital volume control
An amplifier with digital volume control can be designed predictably due to the simplicity of the circuit, which utilizes a single chip, the TDA8551. This series of mini amplifiers with digital volume control operates as a BTL (Bridge-Tied Load) amplifier...
Low-Drift/Low-Noise Dc Amplifier
Figure 39-2's circuit combines a low-noise operational amplifier, IC1, with a chopper-based carrier-modulation scheme to achieve a low-noise, low-drift DC amplifier whose performance exceeds any currently available monolithic amplifier. The amplifier's offset is less than 1 mV, and its drift...
