Excalibur High-Speed Low-Power Precision Operational Amplifier

The TLE2021xM,

TLE2022xM, and TLE2024xM (TLE202xM) devices are precision, high-speed, low-power

operational amplifiers using a new Texas Instruments Excalibur process.

These devices combine the best features of the OP21, with a highly improved slew

rate and unity-gain bandwidth.

The complementary bipolar Excalibur

process uses isolated vertical pnp transistors that yield dramatic improvement in

unity-gain bandwidth and slew rate over similar devices.

The addition of a bias circuit in

conjunction with this process results in extremely stable parameters with both time

and temperature. Therefore, a precision device remains a precision device even with

changes in temperature and over years of use.

This combination of excellent dc

performance with a common-mode input voltage range that includes the negative rail

makes these devices an excellent choice for low-level signal conditioning

applications in either single-supply or split-supply configurations. In addition,

these devices offer phase-reversal protection circuitry that eliminates an

unexpected change in output states when one of the inputs is less than the negative

supply rail.

A variety of available options

includes ceramic DIP and chip-carrier versions for high-density systems

applications.

The M-suffix devices are

characterized for operation over the full military temperature range of –55°C to

+125°C.
