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.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTES: 1. All voltage values, except differential voltages, are with respect to the midpoint between V

2. Differential voltages are at IN+ with respect to IN–. Excessive current flows if a differential input voltage in excess of approximately
±1.2 V is applied between the inputs unless some limiting resistance is used.

3. The output can be shorted to either supply. Temperature and/or supply voltages must be limited to ensure that the maximum
dissipation rating is not exceeded.

APPLICATION INFORMATION

voltage-follower applications

The TLE22x7C circuitry includes input-protection diodes to limit the voltage across the input transistors;
however, no provision is made in the circuit to limit the current if these diodes are forward biased. This condition
can occur when the device is operated in the voltage-follower configuration and driven with a fast, large-signal
pulse. A feedback resistor is recommended to limit the current to a maximum of 1 mA to prevent degradation
of the device. Also, this feedback resistor forms a pole with the input capacitance of the device. For feedback
resistor values greater than 10 kΩ, this pole degrades the amplifier’s phase margin. This problem can be
alleviated by adding a capacitor (20 pF to 50 pF) in parallel with the feedback resistor (see Figure 53).
