hi Chris
thanks very much for your detail test.
but i can't undrstand you said "This 6dB difference comes from the fact that for non-inverting we divide the result by 101 or 40dB and inverting by 51 or 36dB. ". why non-inverting result divided…
Part Number: OPA1612 Hi，
i'm using opa1612 to design a single end to differential circuit. schematic as follows.
all resistor used in schematic are thin film and caps are NPO. 1665.Desktop.rar
VF3,VF4 have very good thd about -125dbc(1khz, 6vpp sin…
Part Number: OPA1612 Other Parts Discussed in Thread: DRV134 Hi,
i am building a differential audio buffer input.
Because i do not need any gain, two follower topolgies seems to be better in terms of performances instead of two inverting or non-inverting…
Part Number: OPA1612 Other Parts Discussed in Thread: PCM1794A Dear all,
I want to design a I/V and differential output stage for the PCM1794A by using the OPA1612. The supply voltage for the OPA1612 shall be +/- 12V.
What maximum current requirement…
Part Number: Hi all,
i am building an input stage design with OPA1612 with TINA for TPA3255 (PFFB) and quite surprised by somme results in terms of THD.
Fourrier analysis show a very high THD calculation of 0.11163% !
Several calculation shows that…
Part Number: OPA1612 Other Parts Discussed in Thread: OPA1611 Hi all,
i am working on a high end amplifier and would like to use OPA1612 as state of the art.
I am thinking about the current input noise which can be carefuly calculated as the source resistance…
Part Number: OPA1612 Other Parts Discussed in Thread: TINA-TI , OPA1611 Hi Team,
We have received a request from a customer for a simulation file of OPA1612 for Altium Designer. I have shared the PSpice model from this link https://www.ti.com/lit/zip/s…
Part Number: OPA1612 Other Parts Discussed in Thread: TEST I made a simple measure-amplifier with 20dB gain,
Straight feedback is with 200 Ohms parallel to -input, and 1800 n series, supply: 2x15V
Harmonic Distortion (pure D3: 3kHz from 1kHz) is much higher…
Part Number: OPA1612 Other Parts Discussed in Thread: TIPD177 , PCM1690 Hello All,
I have been making a circuit based on the TI reference design TIPD 177 and I have a question regarding the circuit.
Attached is my schematics and it's mostly the same as…
Part Number: OPA1612
On the OPA1612 we can see that with R source In one leg) over 600R distortion increases
In my design , I have a summing amp that has R source of 3k and 1k
I would like to know how distortion increases when both inputs have R source…
