Hi Archie,
What is the single supply voltage?
It is impossible to output 0V to 3.3V linearly with a single 3.3V supply, as even "rail-to-rail" op amps have output swing limitations typically 10s of mV from the rail. For OPA1671 the linear output swing…
Part Number: OPA1671
HI, I was wondering if OPA1671 has internal protection diodes. does anyone know?
I intend to use the opamp as a non inverting amplifier.
Do you suggest to use also discrete diodes to protect from overvoltage spikes?
would it be better…
Part Number: OPA1671 Hi TI support team,
We are considering to use OPA1671 in our circuit. During my simulation with TI PSPICE, it popped error "ORCAP -15098". This OPA1671 simulation project file is what I downloaded from TI website directly. I didn…
Part Number: OPA1671 Hello Guys,
Good day.
Our customer wanted to know what is the maximum voltage the non-inverting input of this part can withstand without being powered? He's using this opamp for a buffering circuit in his design to measure battery…
Part Number: OPA1671 Other Parts Discussed in Thread: TLV6741 , OPA1641 We are designing signal conditioning for a piezo microphone and are thus concerned with input voltage protection to clamp any high voltages generated from impact to the mic. The OPA1641…
Part Number: OPA1671 Hi Expert,
Customer use OPA1671 and see output a 62Hz carrier on 1KHz tone(even in without 1KHz tone condition). We though it might be came from 5V supply but didn't see that frequency. Do you have any idea about it and how to remove…
Part Number: OPA1671 Other Parts Discussed in Thread: TIPD181 , OPA1632 , TLV320AIC3104 Hello,
I have a few questions regarding microphone pre-amp design using the OPA1671.
Is there a reference design for both single-ended or differential-ended output…
Part Number: OPA1671 for OPA1671，the datasheet show that the IC is rail to rail out
but look the graph.the Vs=±2.5V,but the output voltage is ±2.7V,why?
Hi Santhosh,
You have this amp. stuck in the low supply rail. In order for this to work at all, the DC bias nodes need to be in a place were the amp. can operate in the linear region -
We do have several electret mic. designs available on ti.com. The…
