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.
