Part Number: OPA1612 Other Parts Discussed in Thread: OPA1656 I'm up to, to design a 3rd or 4th order 20 Hz high pass filter with ultra low distortion. Does anybody know design advantages of choosing a certain topology? Sallen-Key, variable state, etc…
Part Number: OPA1612 Other Parts Discussed in Thread: PCM1794A Hello Mr or Mrs.
Happy new year~!I am always grateful for your help. :)
I am designing a circuit which is related DAC output and it confuses me.
This is a PCM1794a reference TINA simulation…
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 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 than specs: -100dBc (200uV) at…
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: 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: 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…
