First amp in AD8592 is unity gain buffer whose output feeds -IN of second amp in open loop, i.e. used as a comparator. +IN of second amp is used as reference for comparator.The whole chip is duty cycled using shutdown pin. During shutdown mode, +IN of…
Hi,
When the AD9591/AD8592/AD8594 op amps are shutdown, their OUT pins are high impedance. What voltage can they tolerate? (I have the OUT pin connected to a line that's sometimes used as the op amp's output and other times used as an input signal.)…
Hi All,
One of my customer is looking for low cost headphone amplifier.
Specification is >100mW into 32 ohm headphone.
Is AD8592 eligible device for his application?
Best Regards,
Ricky
Hi, all
I'm looking for op amp with shutdown function,and high impedance when in shutdown.
Is the output of the ADA4691-2 this function?
Are all amplifier outputs in a high impedance state, when in shutdown mode?
There is no description in the…
Elias,
What does TRRS mean??
What is your highest signal frequency?
Depending on whether you need to go to DC or not and can AC couple, you could use op amps
that have millivolts of offset, rather than <100 uV which drives up the price.

参考ADI 应用笔记AN_581《单电源应用中的偏置和去耦运算放大器》设计直流耦合电池供电电路,在P6底部提到电路中 RA,RB电阻阻值的选择需要查看AD663A 数据手册,我查过后发现没有AD663A这款芯片,AD6634/6635/6636是已经停产了的模数转换器,数据手册中也没看到这一部分的内容,这个要怎么解决呢?
问题2:该电路中,使用了一个跟随器电路,它是起隔离的作用吗?但是为什么反相端和输出端之间连接了一个110k欧姆的电阻呢?
