Part Number: LPV821 Other Parts Discussed in Thread: LM321 Hi,
We are using LPV821 in a current sensing application in our dimmer design. Below the differential amplifier configuration we used to amplify the very low voltage drop across the 10 milliOhm…
Part Number: LPV821 Other Parts Discussed in Thread: OPA320
Hi Team, We are designing a trans-impedance amplifier using LPV821DBVR in one of our products. The same is to detect the ambient lighting in a room The op-amp will be powered from a 3.3V source…
Part Number: LPV821 Other Parts Discussed in Thread: LPV822 , LPV812 , TLV2333 The datasheet from 2017 states that a LPV822 is "planned for near-future release". Will there be an update on the roadmap in the near future?
Part Number: LPV821 Hi,
I am making a high side current sense using LPV821 and Si7948(PMOS from Vishay).
During simulation(Transient analysis) I can see a peak initially. Please see the attached image. May I know is this due to the fault in my circuit…
sorry Vahid
I was responding to your previous posting, not your latest.
It does sound like the input is damaged. their are back to back diodes between the input pins. It is possible that they were damaged somehow. do you have another LPV821 to experiment…
Part Number: LPV821 The Application Note SNOA968A–August 2017–Revised October 2017 relating to LPV821 shows in Figure 5 an AC/DC converter supplying power to the amplifier.
However the core of the problem in these kinds of 'no neutral' environment applications…
Hi Jefferey,
I am certainly not intending to make this more difficult to understand. I am just trying to make sure that the input/output conditions presented to LPV821 Op amps assures they operate correctly in the application.
The LPV821 has a common…

What closed loop bandwidth do you require. The lpv821 has 8kHz of unity gain bandwidth.
The more gain I use, the less closed loop bandwidth the circuit will have. But using higher gain allows me to use a smaller shunt resistor value and thus…
