We see from your search that you're looking for information on the term "Operational amplifiers",
and we have a large number of manufacturers' news releases and technical articles here on Electronicstalk which will be of interest.
Let me be your guide.
Start with
the news release Analogue IC takes adjustable resistors onboard from
Microbridge, which we summarised at the time by saying "The MBSTC-02 incorporates low-noise operational amplifiers with Rejustors to provide precise signal conditioning with integrated temperature correction".
A couple of weeks before,
we featured the news release TV power controller steps up and down from
Maxim Integrated Products: "The MAX17014 can generate all the supply rails needed for the TFT-LCD panels used in TVs and monitors".
In October 2007, we covered the news from National Semiconductor
concerning its PowerWise op amps
- take a look at Operational amplifiers provide signal conditioning
which says: "The LMP7707 single, LMP7708 dual, LMP7709 quad, LMP7717 single and LMP7718 dual are the latest additions to the National Semiconductor's PowerWise range".
Take a look also at the news release from Texas Instruments (April 2006-), SAR convertors improve linearity,
as well as Op amps offer low noise and high accuracy from National Semiconductor,
and Frugal op amps maintain high linearity from Analog Devices.
