HI KB,
If I understood correctly, the application requires an output voltage of 10V, at 500-kHz, with the TIA configured with the 400Ω gain resistor. The TIA needs to be able to source more than 25mA, and provide high enough slew-rate to support…
Part Number: OPA2156 Other Parts Discussed in Thread: OPA2677 Hi,
do we have any data regarding Slew rate of OPA2156 across its operating temperature range? Can the Slew rate drop from typical 40V/us to as low as 20V/us at high temepratures?
Thanks.
Part Number: OPA2156 Hi Team,
It is a regulation of Typ.40V/us of slwe rate. Is there a difference in rising and falling slew rates?
If there is a difference in the same conditions, how much is that?
Let me know what you think about the conditions described…
Part Number: OPA2156
In the datasheet of OPA2156, at the begining, the feature section:
Low offset voltage: ±25 µV
But latter, is shows 25uV is only the typical value, and only for PMOS, the offset of NMOS is more worse than that. I'm not…
Part Number: OPA2156 Other Parts Discussed in Thread: OPA564 I’m designing a circuit that requires more output current than a single device can deliver - would it be safe to put multiple OPA2156 in parallel to increase the output current?
Hey Ron,
No problem. I will take a look at the previous devices you mentioned for a comparison and try to narrow down some good suggestions for you.
What is the intended application that this amplifier will be used for. Will it be used to drive a speaker…
HI JC,
The OPA2156's PSpice and TIna-TI Spice models can be download from the link below. Do you want us to check something?
