240x160 COG LCD display
|
| |
I am looking for a display 240x160 with a build in controller and LED backlight. I have got a few manufactures that want to build a custom display for me, but I can not seem to find an off-the-shelf display. Does anyone know of a display like this. Serial or parallel interface is OK. Thanks donald... more »

So to be on the safe side I decided to clean it.... more »

Interesting new op amp--like a LT1128 on Prozac
|
| |
[link] This is a potentially very nice part--0.9 nV, 2.4 pA, 1.5 pF Cin, 33 MHz, +- 15V. The dynamic range is stunning, especially with that low input capacitance--about a quarter of the LT1128's. With quiet feedback (i.e. not a room temperature resistor) you could do some fun... more »
