Part Number: OPA2347 Other Parts Discussed in Thread: OPA2310 Hi~
A buffer circuit was configured with OPA2347.
The output is 0.35 V/60 Hz when the input is N.C.
I want to know why it's printed like this.( For reference, the Korean power supply…
Part Number: TLV9001 Other Parts Discussed in Thread: OPA2206 , OPA2310 Hello team,
Does signal input without power supply give damage to TLV9001?
(3V DC is input to input pin without power supply. The buffer configuration will be used for monitoring…
Part Number: TLV9064 Other Parts Discussed in Thread: TLV2262 , TLV9062 , OPA2310 , OPA2323 Hello,
I am designing a circuit to measure the voltage of a glass electrode sensor which has a very high output impedance (>100Meg). Most opamps have an even…
Part Number: TL074 Other Parts Discussed in Thread: , OPA2206 , OPA206 , OPA2310 , TLV9154 Hi team,
Could inverting/ no-inverting input be high impedance when VCC not powered? Thanks.
Hi Rohan,
Correct, your circuit would violate the common mode input specification of the device with 5V supply.
You could try attenuating the signal and applying amplifier gain to compensate for this, or use a RRIO amplifier
Is there a certain range…
Peng,
Kai is correct, this is caused by the forward voltage drop of the ESD diodes.
Figure 2.2 of the Op Amp ESD Protection Structures App Note shows how the ESD diodes conduct when VCC is unconnected and IN+ has a positive voltage above the Vf…
to User473,
I searched all the op amp portfolio with the parametric search (precision, general purpose, and high-speed). There are 6 options with temperatures of 150C and above (see attached). The best match is the OPA211-HT (210C max). This is the…
