Part Number: OPA2228 Other Parts Discussed in Thread: PCM1789 , , OPA228 , OPA227 , TINA-TI Hello!
Is OPAx228 a no-go for active filters? I've bought a couple of them before realizing they're not unity-gain stable.
The datasheet does say that they…
Hi Annie,
It is possible to adjust the gain of the circuit so that it uses ±5V, but as the first stage is a trans-impedance amplifier, a negative supply is required. If they do not want a negative supply, then maybe they could consider a voltage output…
So, TPA6138 can act as both LPF and amplifier simultaneously? no need for separate LPF?
Also the output of PCM1789 is 4Vpp centered at 2.5V while the input to the TPA6138 is 0V to 3.3V, so do i need to attenuate input signal to TPA6138? my attached…
Hi Nigel,
I think that you could try the next alternatives. You can use TAS2552's digital audio input instead of PCM1789 or you can connect the PCM1789 to TAS2552's analog audio input.
Please let me know your thoughts.
Best Regards

Hi MJ,
The best fit here is probably the PCM1789-Q1. Otherwise you can consider some of the TAS devices which integrate a class-D amplifier. The specific device depends on output power requirements.
Thanks,
Paul
Part Number: PCM1754-Q1 Other Parts Discussed in Thread: PCM1754 , , TAS5411-Q1 , PCM1789-Q1 Hi team,
customer use TAS5411-Q1, it is differential input. customer would like use PCM1754 as DAC. does the PCM1754-Q1 can output differential signals.
