1. We are using the AD8599 at ± 15V.  When the room temperature is 25 ° C, device temperature  is 80 ° C. Are these normal?

• ### Noise optimizing AD8599 &&

Good day,

I have a task to optimize noise in BW 10Hz - 10kHz.

Voltage gain shall be around 20..50. OA connected directly to source of signal,

which has impedance 1kOm DC and 50Om AC. OA connected to middle point of R1/R2 divider,

where R1 connected…

### Q

I have to use an AD8599 and I tried to measure the CMRR with Vcc=+/-5V with
-2V<Vcm<2V (as noted in the datasheet). The result is about 110bB (vs 120dB
Min). I tried using conditions Vcc=+/-15V with -12.5V<Vcm<12.5V and it's the …

### A

resistance is omitted from the datasheet (Rev. C 12/09), as these devices are
typically used with impedances…
• ### AD8599 voltage range - okay for phonostage replacement

Hello,

I want to upgrade the old opamp in my phonostage. The voltage 22+/- and would that be okay to use AD8599?

Thank you

Kind Regards

• ### AD8599 CMRR measurement and mistakes on datasheet ?

Hello my friends,

• ### Would the AD8599 suit the circuit of the phonostage?

Hello,

I was the AD8599 in both my Philips and Marantz CD players and love the sound.

I have recently rebuilt my Technics SU-V9, some old capacitors gave out.

Would the AD8599 suit this circuit in the phonostage section of the amplifier ?  17+/- voltage…
