AD8597 Single Power Supply

PEDALATOR

May i use the AD8597 powered from a single supply +5V/GND (input = output = 2.5V DC voltage ref) ?
Because it is only specified with symetrical power (±15V and ±5V).
Is there any drawback for powering any AOP specified for symetrical power, with a single…

AD797: Maximum junction temperature Tj

GenevaCooper

Q

I can’t find the maximum junction temerature of AD797 in its datasheet. What is
the value?

A

The max junction temperature is 150°C, same as other parts on the same process.

By the way, the AD797 came out in 1992 and is on a very old process…

RE: Replacement for LT1128

GlenBrisebois

LT1028 will work if the circuit has a noise gain of 2 or more. LT1007 is also worth a try; it has higher voltage noise but lower current noise (and pin 5 is open, not boost). Also perhaps AD8597 (with pins 1, 5, and 8 open). ADA4898-1 and ADA4004-1 are…

AD8597_spice模型

adiadmin

请提供IC AD8597ARZ的spice模型。是否可以使用AD8599的SPICE模型来仿真AD8597？

AD8597和AD8599数据手册（第6页至第14页）所示的典型工作特性不相同。因此，我认为不能将AD8599模型用于AD8597。请确认并提供AD8597的模型。

RE: AD4007 / AD4003 - TIA interface

tbet2017

Thank you for the feedback, LLoben !

The application basically is scanning with a step frequency of 200kHz. The settlement time of the stimulus (input of the photodiode) is pretty fast (<300ns). For the photodiode/TIA side simulation/calculation based…

RE: Why does the AD797 stay saturate (overload recovery takes infinite time) ?

ARC

Dear Harry,

Sorry for the late answer and thank you for your response.

You are right, the input voltage noise of the AD797 can go up to 1.2nV/sqrt(Hz) and no more than 1.15nV/sqrt(Hz) for the AD8597. So I have to order a lot of components today, I will…

RE: LTspice库里面找不到AD8692元件怎么办？

ALee687

AD8692用AD8691的spice模型，AD8692是双运放，AD8691是单运放。

其他器件如果在LTspice中找不到，可以到ADI官网上下载相关spice模型（.cir文件），每一个运放的页面基本都能找到相关的spice模型（一般在Datasheet下面）。然后将cir文件导入到LTspice中自建电路模型。

附件中是如何在LTspice中导入模型文件的方法：

RE: 关于AD8099放大器的问题

cnhtzxb@163.com

有点不对路，AD8099用于高频低增益，20倍没问题30倍得试试看。考虑考虑AD8597之类的吧。

Hi Jordyn,

Thanks for your reply.

I have reconfirmed and the measurement range is 70mV max. My people have

refused to give details of Thermocouple but they mentioned that it is

chromel -alumel type.

I also saw the table you have mentioned. but I…
