description
The TLE22x7C combines innovative circuit
design expertise and high-quality process control
techniques to produce a level of ac performance
and dc precision previously unavailable in dual
operational amplifiers. This device allows
upgrades to systems that use lower-precision
devices and is manufactured using Texas
Instruments state-of-the-art Excalibur process.

In the area of dc precision, the TLE22x7C offers a typical offset voltage of 100 µV, a common-mode rejection
ratio of 115 dB (typ), a supply voltage rejection ratio of 120 dB (typ), and a dc gain of 45 V/µV (typ).
The ac performance is highlighted by a typical unity-gain bandwidth specification of 15 MHz, 55° of phase
margin, and noise voltage specifications of 3.3 nV/√Hz and 2.5 nV/√Hz at frequencies of 10 Hz and 1 kHz,
respectively.
The TLE22x7C is available in a wide variety of packages, including the industry standard 16-pin small-outline
wide-body version for high-density system applications. This device is characterized for operation from 0°C to
70°C.
