Tl074 circuit

I'm wondering if I can please get some help: I'm trying to make "accurate" (as in highly granular / large range of values) light readings from a BPW34 photodiode, through a TL074, in to an Arduino Mega. Refer attached image for circuit. As it is, the arduino reports about 920 in ambient light, and 850 with a bright lamp shining right at the. Trying to understand more the circuit I simulated, and measured the current AM1, the simulation shows an square current of +/- 10mA. Is the TL074 capable of produce this current needed for this circuit? Is the TL084 capable of producing it?, in the datasheet I can't find how to obtain the maximum Iout..

I've reached the conclusion that all my TL072's and TL074's bought via AliExpress from China are fakes. Both SMD and THT versions. Most likely they are LM324 or similar. The particular problem I've had is the slew rate being waaay off specification, something like 30 times slower than specified which is easily seen in my VCO as the output square wave starts to slew into triangles at around 4 kHz. An audio source, like a mixer, preamp, EQ, or a recorder, is fed to the input of the Electronic Crossover Circuit. This signal is either A. Nice circuit. The balance control is quite similar to what D. Self has been suggesting. 10dB of range seems like a lot though. Considering the opamps are an absolutely marginal cost in such a project (compared to the switches, pots and so on), why bother with the tl074 and not go for the opa1644 (or even the opa1654 at half the price) ?.

The TL074 JFET-input operational amplifier family is designed to offer a wider selection than any previously developed operational amplifier family. Each of these JFET-input operational amplifiers incorporates well-matched, high-voltage JFET and bipolar transistors in a monolithic integrated circuit.The devices feature high slew rates, low-input bias and offset currents, and low offset-voltage .... I'm hoping to find a simple mix/blend circuit that uses 1 op-amp. 2 op-amps is fine though. I did a quick search here and saw two related threads. One guy needed it for Mhz frequencies, and the other thread had suggestions for transistor based (which I'm not against, but would hope to be able to utilize the left over opamp in the TL074) Thanks!. TL084 is a high-speed operational amplifier integrated circuit consisting of a high voltage JFET and bipolar transistor.An interesting project, using TL084 to build a 100w+100w stereo ... The Op-Amp is very similar to TL074 but has high noise immunity and better offset characteristics. The '74 has lower noise figure, so is better for AC signals.

Tags. TL074. The TL07xx JFET-input operational amplifiers incorporate well-matched, high-voltage JFET and bipolar transistors in a monolithic integrated circuit. The devices feature high slew rates, low-input bias and offset currents, and low offset-voltage temperature coefficient. The low harmonic distortion and low noise make the TL07x series.

Mar 01, 2022 · Hi all, This stumped me last night. I was working on a project where I need to multiplex the audio-rate output signal of a DAC into several channels. I built a sample-and-hold circuit on breadboard: ESP32 DAC -> TL074 (buffer) -> 74HC4067 mux -> 0.1uF cap (to gnd) -> TL074 (buffer) -> high-ish z load The signal from the DAC is the full 3v3 p-p and the opamps are on a +/-5V supply I cobbled .... The TL074, TL074A, and TL074B are high-speed JFET input single operational amplifiers. Each of these JFET input operational amplifiers incorporates well matched, high-voltage JFET and bipolar transistors in a monolithic integrated circuit.
