Hi Vijay,
Vijay Kolaventy said: U5 is not required in case of buffered ADC. I have not used an op amp in the circuit as ADS1219 input is buffered. Please correct me if I am wrong
Yes, the ADS1219 has input buffers, but its input bias current of 5nA would…
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 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' en…
Part Number: LPV821 Other Parts Discussed in Thread: LM7705 , BQ76920 Hello;
I need a sanity check regarding the LPV821's power supply capabilities. Because my client's application requires accurately measuring +/- 400A, the sense resistor is 100uOhm…
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…
Part Number: LPV821 Hello,
I'm using the LPV821 op-amp for a buffer circuit (voltage follower). Below is my circuit, where the Vin is a non-deal source with very high output resistance (~700KOhm) and the desired output has the same voltage as the input…
Part Number: LPV821 Other Parts Discussed in Thread: TLV2401 , TLV8801 , Dear,
I have no previous experience with op-amps.
I have used the TI selection tool but, to be honest, the number of parameters is overwhelming :)
During my preliminar searches, seems…
