The operational amplifier (op amp) is an important part of any analog signal chain, often working as a crucial part of the interface between sensors and our world-leading ADCs. Common analog op amp functions include gain, buffering, filtering, and level-shifting. Analog Devices’ portfolio provi...
There is a working circuit where I am using MCP6044. I happened to test TL074 in the circuit and had error. I was surprised as by specifications and being an op-amp, the output was completely unexpected. To probe further, I made the circuit schematic in LTspice, first using...
An op amp circuit that would normally limit changes to about 52 kHz has an unusually-placed JFET and claims to boost the bandwidth to 350 kHz. Continue reading “The Disappearing Capacitor” → Posted in Misc HacksTagged bootstrapping, op amps, photodiode ...
SPICE is not case sensitive. It would treat 1M, as 1m, so to get round this, you need to set the value to 1Meg, instead of 1M.I believe guitar pickups have a fairly high impedance. I'd up the values of R1 & R2 to 1M and move R3 to in-between the op-amp's +input and the...
In practical level-shift, attenuate/gain, and active filter circuits, we have some basic op amp requirements for an amplifier supporting ±5 V signal while working in a 1 kΩ environment and achieving 1 ppm linearity shown in Table 1....
The second is that there is no negative supply voltage so there can not be any negative results for any outputs. This has been noted by others too. Third, when we analyze a circuit we have to recognize the paradigm we are working under. That means we have to pay attention to the main...
An operational amplifier is a high-gain amplifier with a differential input stage. However, most op-amp circuits do not have high gain and do not perform differential amplification. Rather, we use negative feedback to turn a high-gain differential amplifier into a high-performance and user-frien...
The OPx177 family consists of very high precision, single, dual, and quad amplifiers featuring extremely low offset voltage and drift, low input bias current, low noise, and low power consump-tion. Ou
