Car Antenna Amplifier Circuit
The total gain of the car antenna amplifier is approximately 30 dB, with an input impedance of around 10 kΩ at 30 MHz. The amplifier should be mounted directly at the base of the antenna to prevent signal losses attributed...
Precision Amplifiers
It has been mentioned that the operational amplifier (op amp) in the second stage may be damaged. Confirmation is requested by testing the op amp in a buffer configuration or any simple configuration. This test is necessary to ascertain whether...
ADT70 internal functional block diagram
The ADI I70 is a signal conditioning integrated circuit designed for RTD/PRTD applications, particularly suitable for 1K and 100Ω platinum RTDs (PRTDs). The ADT70 features an integrated instrumentation amplifier, an operational amplifier, a 2.5V reference power supply, and a matching...
Operational Amplifier tutorial
Since the 1970s, a remarkable era in technology, amplifiers have been available in integrated chip form, eliminating the need to construct them from numerous discrete transistors. This video provides an overview of operational amplifiers (op amps) and includes an example...
Safe-opamp-circuit
In intrinsically safe applications, it is sometimes necessary to separate sections of circuitry using resistors that limit current under fault conditions. The circuit presented offers an accurate analog output with effectively zero output impedance, despite the presence of resistors in...
Comparator with variable hysteresis
An operational amplifier can be utilized as an effective device for analog comparator applications that necessitate two distinct trip points. The incorporation of a positive feedback network introduces a precise variable hysteresis into the conventional comparator switching action. This feedback...
Amplifying DC Diode Detector Output
The small DC voltages at the output of the diode detector are challenging to amplify accurately due to DC offsets introduced by any operational amplifier (op-amp) and low-frequency noise (1/f noise). A solution to these issues is to chop the...
Op-Amp Circuit: Difference Amplifier
This circuit is a difference amplifier. It functions as an inverting amplifier that enables the subtraction of two voltages, effectively performing a summation.
The difference amplifier is a fundamental circuit configuration in analog electronics, primarily used for amplifying the difference between...
Simple DC to 20 MHz Driver
The output cable from my 20 MHz function/sweep generator dangled over the side of the workbench, the alligator clip hovering over the floor. Deeply engrossed in a project, I moved the power strip on the floor a little closer so...
