I am considering using this op amp in a power supply design. OPA544T http://www.ti.com/lit/ds/symlink/opa544.pdf The specs say it has a 2A minimum output current. Can someone clarify what "minimum" stands for. Thanks, Mario

What is the best method of amplifying output current of op-amp. I need a cheap solution without using power amps. Thanks

The above circuit represents my current configuration. The circuit is used to measure a ± 10.0 VDC signal. R2 prevents my circuit from floating and provides a good high impedance. R3 and R4 is a voltage divider that reduces the ±10.0 Volt signal. Someone recommended on this forum, that...

What is the best way to increase output current of an op amp?

Greetings, I've been experiencing sparodic op amp failure (shorting the power supplies is one failure) in one of my designs. The op-amp (OPA 2277) is being used as a buffer. I was made aware that it is possible to that the inputs are getting a voltage before the power supply pins are. What...

Hi, My application consist of two parts. The first part of the circuit puts a 0-20mA signal through a 500 ohm resistor for an equivalent voltage of 0 to 10 VDC. The second part of the circuit consists of a voltage divider that accepts a ±10 VDC signal. My circuit is part of a larger data...

Hello Everyone, I am fairly new to circuit layout. I've designed a simple strain gage amplifier with a 0 to 10 vdc output. The circuit operates as design with one problem. When put my hand near the sensor wires I get a shift in voltage. 1. What causes this? 2. How can I fix it? 3. What...

What would cause two seperate op-amps to behave different? Problem: I have an instrumentation amplifier configured in the following manner. The first stage amplifies a differential input by G=25. eg, 0.020V * 25 = 0.5V The next stage takes the difference of the two signals and amplifies by G...

Hello Everyone, I am currently working on instrumentation amplifier using digital pots to adjust trim, offset and span. Most digital pots are rated at a ±5V terminal voltage. My question is how do I interpret this? Does it mean I can put a -5 and 5 on each end of the terminals max, since 5...

I am currently designed a simple instrumentation amplifier "INA125" from Burr-Brown. I am powering with a 7662 charge pump to provide a bi-polar voltage. My design specification is that the amplifier operate from 12-24 VDC. The INA125 operates to a max of +/-18 VDC and the charge...

Aside from electrical connections what are the differences between a 3 wire current trasmitter and a 2 wire system. Which one is preferred in industry? Is it dependent on application?
