Part Number: OPA992 Hi,
I'm using the OPA992s 6-pin amplifier as a buffer amplifier. The Power inputs are +12V and -12V. And the input range is +10V to -10V. We are giving the Shutdown signal around 20mV still the output of opamp is not getting. please…
Part Number: OPA992 Other Parts Discussed in Thread: ISO224 Hi,
We are using OPA992 in our design as a summing amplifier.
As per attached schematic we have done the design and PCB also fabricated.
During testing we are not getting the summing operation…

Recently, I design Hi-Z TIA as this picture: The feedback resistor is 100Meg ohm I read datasheet for OPA992 which mentioned its *differential input impedance* is 100Meg…
Part Number: OPA992-Q1 Here is my TIA circuit
Since this circuit has high feedback resistor (100Meg) for OP-AMP,
Vo would be about 300mV when power off due to environment light,
and Vo would be about 100 mV when power on due to 0.1 bias of V+,
as this…

Regarding …
Part Number: OPA992 What if using +35V and -5V for OPA992 power supply?Will it case unstable or damage?
Because my signal DC component only touch -3V buy need too up to+30V
Any think i need to check when using Non-symmetry supply rail?
Thank You
Li,
This could work if there is enough ICC at min output voltage to keep PMOS on.
Gate could be 2.5V instead for a lower Vout min. This would probably be better.
During ICC below 2.5V, both 2.5V and 5V will be close to ICC so PMOS off either way.

Hello Marek,
I created a charge amplifier using OPA992, I am attaching tina ti schematic, I am seeing very high noise levels, what is going wrong here?
Please find attached schematic 8507.RX_chargeAmp.TSC
The V CM specification in section 6.5 says that the OPA593 needs a headroom of 3.5 V to the positive supply.
The OPA992 has rail-to-rail inputs and outputs.
