7 Detailed Description
7.1 Overview
The OPAx828 are low-noise, high-speed JFET input amplifiers that provide the highest levels of precision
and accuracy. Each device is laser trimmed in production to provide the lowest input-referred offset voltage.
Likewise, the input-referred offset voltage drift is trimmed and specified over the junction temperature range of
–40°C to +125°C. Each device also has the quiescent current laser trimmed to minimize part-to-part variations
for dynamic parameters such as input-referred noise voltage, gain-bandwidth product, slew rate, and settling
time. The combination of low-noise, dc precision, and dynamic performance of the OPAx828 is unsurpassed
in the industry with the OPAx828 taking full advantage of the latest and most advanced high-voltage, SiGe-
complementary, JFET-bipolar process technology.
