Dear Sir/Madam,
Our customer asked as folowing question.
As for your ADA4851-1,What is your output leakage current when /PDN is enabled?
In fact, he has put the transistor 2SC6075 at ADA4851-1 output, and has driven the laser diode.But when he change…
Hi Lucas,You are correct, the failure mechanism is not the over-voltage per se, but the current that the over-voltage current causes. Limiting the current flowing to the input by less than 5mA is the rule of of thumb for most of the op amps. No damage…
Hi
For example, ADA4853-1 has power down pin.
Is that output high-z condition, when it has disabled?
If that is true, so we can design exclusive output without analog switch, I think.
(tied these outputs. and turn on the only one device)
Is there…
ADA4851-1 data sheet doesn't have maximum value definition of Input Offset Voltage Drift.
Could you provide rough estimation of it?

用过ADA4851，谢谢！
I have a request for Maximum power dissipation (Derating curve) of AD8418A.
For the case of ADA4851 ,I can see thermal resistance(table 5) and Derating curve (figure 5) of page 10 on data sheet.
Do you have these data for AD8418A same as ADA4851?
Hello Sai,
For a RRIO replacement for the ADA4851-4, I would recommend the AD8040 The AD8040 is 125MHz RRIO low power quad op amp, that should meet your needs nicely.

We are using an ADA4851-4 where the op amps are in a typical non-inverting configuration with a input resistance of, say, 2K ohms and a 2K resistor from the positive input to ground. For a signal bandwidth of 30 MHz, what is a good range of feedback resistor…
Hi Kawa,
The Table of Specifications: SPECIFICATIONS WITH +3 V SUPPLY, SPECIFICATIONS WITH +5 V SUPPLY and SPECIFICATIONS WITH ±5 V SUPPLY shows the ADA4851 typical performance at supplies +3V, +5V and ±5, respectively. If you notice, with different…
大家好，我最近在做一个210kHz信号调理电路，原来板子上单端转差分使用的芯片是ADA4851-4，查看手册比较性能参数，发现ADA4807-4较ADA4851-4更好，这边想问下，能否用ADA4807-4替换原来的芯片，会不会有问题？
