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 below?

(a) Other recommended Opamp part numbers

(b) required opamp specification for this I-V circuit or how calculate them

Hello,

In general you can use many different operational amplifier available that are low distortion and low-noise. In their datasheet , usually the first page, they mention the application. you want to use op amps that are suitable for audio application or line driver. A good alternative is OPA134 or OPA2134. Another suggestion is The OPA6x7 or OPA604

Regards,

Arash
