Opamp dual package IC configuration

Option 2 will have slightly less cross-talk between the two signal channels. For me, that makes it the starting point, especially with a channel gain of almost 70 dB, and there has to be a sound ...

Is my solution to this differential receiver circuit calculation correct?

You can apply super position theorem (SPST),for solving these kind of circuits. Please see the answer below.

Opamp dual package IC configuration

This quite depends on what the sensor signals signify. In particular, whether "signal absent" is an important case to handle. When it is, crosstalk between the processing paths of the two ...

Implementation of Circuit in AN104 for Load Transient Test

A1 controls the current in Q1; it controls its output so that the voltage at its -ve input equals the voltage at its positive input. For a 1V at +in, Q1 current will be 10A, so the transfer ratio is ...

How can the power of an oscillator be calculated?

In the LTspice simulator you appear to be using you can plot the power consumed by holding the alt key and left-clicking the voltage source. On the plot pane you can hold control and left-click the ...

What is the proper way to make a configurable split-supply voltage clamp with voltage dividers?

You'll need to take care not to exceed the current sink/source ability of the op-amp. You shouldn't really ask for more than 10mA, which would occur if the voltage across R1 (R43) (100Ω) exceeded 1V. ...

What is the proper way to make a configurable split-supply voltage clamp with voltage dividers?

If you reconfigure OA2 as an inverting amp, then you need only one voltage divider (R47 and R48). Also, if you add in a pot, then a single adjustment point gets you variable,symmetrical clipping. For ...

How does analog IC benefit from channel length shrinking?

For conventional and low frequency circuits there is little benefit. Typically gain is lower; supply voltages are lower also. Matching don't generally scale with technology nodes, so fur a given ...

NE567 supply voltage

In a comment: all voltages are ground referenced to AC mains ground That's false. They are referenced in a way that makes sense in the particular part of the system. Sometimes you have a system with ...

NE567 supply voltage

Let's take a step back first, as you're not asking how to use that IC - you're asking why voltages are expressed that way in electronics engineering... Electronics engineering consists of two separate ...

NE567 supply voltage

The supply voltage range is simply that for which the IC was designed. As shown in the NE567 schematic, the circuit was designed to be supplied by a positive voltage on pin 4 with ground connected to ...

Level shifter (floating shifting ?)

This comes up frequently in the work I do. I usually use SPDT analog switch chips. Just switch the output between Vss and Vdd depending in the logic input. The DG403 has been my go-to chip here for ...

Opamp dual package IC configuration

I don’t expect serious crosstalk levels, until gross mistakes in routing and bypassing are made. In-chip crosstalk usually is less than 60..80 dB (A haven't found such data for TLV2333, but there's a ...

Is my solution to this differential receiver circuit calculation correct?

Your equation is incorrect, because it assumes the output to be referenced to zero volts (ground). In fact, the output will be offset from 0V by an amount dependent on V2, and will not be the simple ...

Analog switch unpowered state

There are special analog switches for the very purpose. TI calls them FET bus switch. If you take a look at your MAX4737, it specifies analog voltage up to your Vcc, i.e. clamping your analog voltage ...
