Part Number: OPA4170-Q1 Other Parts Discussed in Thread: OPA2990 , OPA4170 Besides the 40V absolute max rating for supply voltage (single supply configuration) for this device, is there any information on the abs max rating for transient conditions? I…
Part Number: OPA4170 Hi,
A capacitive load is connected to the 3 channel output terminal of the OPA4170AIPW.
When the short-circuit current of the output terminal was measured, it was confirmed that the waveform of the short-circuit current of about 20…
Part Number: OPA4170-Q1 Other Parts Discussed in Thread: ISO7740 , OPA170 I recently tried running a SPICE simulation using the model for OPA170 op amp. Positive input is fed from ISO7740 device where voltage transitions from low to high. Negative input…
Part Number: OPA4170-Q1 Other Parts Discussed in Thread: OPA4170 , OPA4171 Hi champs,
My customer evaluated OPA4170 and OPA4171 with attached circutry.
As shown in attached file, when OPA4710 was applied, output sinsoidale waveform shows distortion, but…
Part Number: OPA4170 Hello,
When I think output voltage vs output current for the OPA4170 with Negative feedback loop...
Should we refer the Voltage output swing from rail in Electrical Characteristics?
Or is it for open loop and should we refer Figure…
Hi,
We are using a OPA 4170 opamp at the output of a DAC for amplifying and level shifting the DAC output. However, it is found that the 4170 fails frequently. The ouptut pins of the 4170 have been brought out on to headers for probing. These are not…
Other Parts Discussed in Thread: OPA4170 , TINA-TI Hi,
We are using OPA4170 based control circuit in one of the design. When probed on the pins of OPA4170, I am observing unexpected voltages.
The schematic is attached herewith. With the input to the U22…
Other Parts Discussed in Thread: OPA4170 Hi,
The part OPA4170 looks attractive interms of price and performance.
But, my application demands rail to rail input and output swing. In the datasheet of OPA4170, it is mentioned that the input swing will be…
This is from the OPA4170 folks: OPA4170-Q1: Input current in simulation
In essence, the input impedance doesn't matter under certain conditions because there are diodes that become forward biased for a short duration.
I used the rise/fall times specified…
Sandeep, Welcome to the e2e forums.
The OPA4170 is not rail to rail input. The model will have poor results as a warning when the input range is close to the end. The OPA4170 can run on 3.3V, however it is not the best idea as the input range limitations…
