We see from your search that you're looking for information on the term "Operational amplifier",
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 Buffer keeps noise out of audio applications from
National Semiconductor, which we summarised at the time by saying "The LME49600 can respond to highly dynamic inputs, accurately reproducing these signals without degrading them by adding distortion".
A few weeks before,
we featured the news release DAC settles quickly for high linearity from
Texas Instruments (April 2006-): "The DAC8881 is an attractive option for industrial process control, automatic test equipment, data acquisition systems and communications applications".
In September 2007, we covered the news from Analog Devices
concerning its AD8506
- take a look at Frugal op amps maintain high linearity
which says: "CMOS dual op amp is designed for applications that require precision measurement at low voltage levels with minimal power consumption".
Take a look also at the news release from Texas Instruments (April 2006-), Operational amplifier simplifies designs,
as well as Single-supply amplifiers are trimmed to precision from Texas Instruments (April 2006-),
and Programmable gain amp claims top precision from National Semiconductor.
