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?
I am presently using ADA4851(4 channel) as a unity gain buffer .But it isnt a rail to rail I/O IC and also requires a huge headroom (2.2v)
I am looking for a replacement for this IC which has rail to rail operation or aleast with less headroom(<1v)…
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…
仿真跟实际是一样的,那么ADA4851-4就不适合用在这个电路里。换个型号试试?ADA4891-4?
Hi ,
I am checking a Clipper circuit with ADA4851.
And when simulate with various voltage , I find a relation between the Voltage at non inverting and supply voltage .
When using in 0-5V supply , +3V at non inverting terminal i see that the out is clamped…
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…
hello everyone,i am having a hard time understanding the huge difference in behavior that i see between the single (ADA4851-1) and dual (ADA4851-2) versions of this amplifier.my supply is +- 5Vmy input is a DC to 10mhz, 0 to 1v sinewavei am testing both…
Hi !
I have a question about the ADA4851-x's datasheet.
For example Table.1 t Page4 , it says "SPECIFICATIONS WITH +3V SUPPLY" ,
but at the Table.1 it says Operation Range is 2.7V to 12V.
And also the datasheet is written by each supply…
Hello,I'll be using an ADA4851-1 (supplied +5V) in a high-voltage (up to 60V during a small-time during which the OA isn't supplied, then max 38V in nominal operation) sensing application, with a bridge divider (1:11 with a 100kOhms and a 10kOhms which…
Hi
ADA4851-1 data sheet doesn't have maximum value definition of Input Offset Voltage Drift.
Could you provide rough estimation of it?
