Part Number: OPA134
Dear,
Now, I´m designing alarm tone generator with microcontroller. Microcontroller generate square signal output at 1450Hz. This output have a voltge divider and low pass filter for volume control and attenuation at frequencies outside…
Part Number: OPA134 Other Parts Discussed in Thread: DRV135 , ISO7710 , TINA-TI Hi,
In the last post "OPA134: Useful opam'p for audio tone from microcontroller", was unfinished and now I attach a new and improved design with Single-Channel Digital Isolator…
Part Number: PCM1792A Other Parts Discussed in Thread: PCM1792 , OPA134 , , OPA1612 Figure 37 in the datasheet for the PCM1792 shows a typical OP-AMP setup to first convert the current output of the DAC to a voltage (U1 and U2) and then to add the two differential…
Part Number: OPA134
Need help calculate general purpose line in stage op-amp, Inverting op-amp, single Power Supply +12V
This stage should accept input audio signal from various audio line out.
Since line out output levels usually can vary between 0…
Part Number: THS3217EVM Other Parts Discussed in Thread: OPA134 Hello
We are new to this board and are not sure of having read the manual properly. The issue is we get 4 mV or 40 mV when we use the OPS amplification even if the differential signal we want…
Part Number: PCM1798 Other Parts Discussed in Thread: NE5534 , , OPA2134 , OPA604 , OPA134 In the PCM1798's datasheet, NE5534 is recommended for I-V convert circuit connected to PCM1798 analog output.
But NE5534 is too high for us.
So could you tell me…
Part Number: INA1620 Other Parts Discussed in Thread: BUF634A , , OPA1622 , OPA134 , OPA1688 , OPA1678 , BUF634 , OPA1656 I would like some discussion of a dual INA1620 headset driver circuit version of this, higher supply voltage, compared to an op amp/BUF634A…
Also Tengfei,
This article came up yesterday in a different discussion, explains this in more detail with a step by step example using the OPA134 as an example device,

Part Number: OPA140 Other Parts Discussed in Thread: OPA134 , OPA1642 Hello,
Is OPA140 susceptible to source impedance distortion like older JFET op amps?
The data sheet does not say anything about that distortion and how to minimize it.
For example OPA134…
