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?
Ann,
Has the customer considered the OPA1671?
Also consider the common mode voltage, Vcm operating point. With Vcc = 3V and Vee = -12V the customer may be operating close to the transition region or even into the NMOS region with a 3V signal. If this…
Hi Alexandre,
First of all I would suggest you to use OPA1612 or OPA1671 as part number for your post. Your questions are basically related to those parts and I belong to a different team than the one supporting OPA amplifiers.
I think your current implementation…
Hello Hari,
A single op amp may be used for a very high gain amplifier, but that gain may come at the expense of distortion, bandwidth, noise, etc. I mentioned the OPA1671 previously and it will be used in a simple capacitor coupled inverting amplifier…
