Because of the Thanksgiving holiday in the U.S., TI E2E™ design support forum responses may be delayed from November 25 through December 2. Thank you for your patience.
Other Parts Discussed in Thread: LME49721 , OPA322 , OPA365 , LMP7731 I am using this device in a 2nd order unity gain Sallen-Key low pass filter. R1=R2 = 100k, C1 = .22uF, C2 = .47uF. Vcc = 2.5 volts.
I am seeing about a .250 volt drop across R2 at about…

Hello
Unfortunately LME49710 is using Bipolar process, not CMOS process. So the input bias current is not so Low even this device is using bias cancelling technology. To reduce the offset voltage, You need to use very small input bias current op-amp.…
Other Parts Discussed in Thread: OPA2337 , LME49721 , LME49726 Customer used OPA2337 ,SOT23-8 for audio application,and faced very poor preformance,high noise.
Is the LM49726 is the best recomended solution? any other solution?
Hi Duane,
Unfortunately the LME49721 has a maximum operating supply voltage of 5.5V, so this won't work. the LME49710 would then be the part.
Best Regards,
JD

I have try to check if PCM1795 having reference SCH, but just find PCM1795 datasheet figure 51.
For I/V Section, reference design use NE5534(figure…
Other Parts Discussed in Thread: OPA2354 , OPA320 , LME49721 , OPA365 I'm just looking for some good general purpose low voltage OP amps that are good for audio work, are stabil with moderate amounts of gain, and (VERY IMPORTANT) are available at places like…
