Other Parts Discussed in Thread: ADS52J90 , THS4509 , OPA2300 Hi all, My customer plans to use ADS52J90 for a photo sensor input application.
A signal path is as follows;
Photo sensors -> I/V conversion of a photo diode input (OPA2300) -> single to…
Hello Gerald,
Yes, high speed amplifier group is the correct place for this type of application. Michael already gave really good suggestions. I will add a couple more below and here is an app note for NTSC composite video applications .
LMH6612…
Hello Scott,
The TI's part number OPA2300 is a high-speed operational amp that you can use for a simple dc offset adjustment circuit.
You can find the datasheet on the following link.

Hello K,
To replace the LMH6643 in a peak detector application:
I'd recommend a device such as OPA2300 or OPA2301 (CMOS input, RR output, CM to ground, 5mV offset, 80 V/us slew rate) devices which do not have the over-voltage diodes across the inputs…
Hello Ken and Seb,
I've put together a spreadsheet of the most promising devices for your review and consideration. This spreadsheet uses your conditions:
Cin= 80pF
Required Bandwidth > 10kHz (I've used 100kHz to allow margin)
Min / Max input…
to User473,
I searched all the op amp portfolio with the parametric search (precision, general purpose, and high-speed). There are 6 options with temperatures of 150C and above (see attached). The best match is the OPA211-HT (210C max). This is the…
