The TLE2021-Q1, TLE2022-Q1, TLE2024-Q1 and TLE2021A-Q1, TLE2022A-Q1 devices (all referred to in this data sheet as TLE202x-Q1) are precision, high-speed, low-power operational amplifiers using a new Texas Instruments bipolar process. The A-suffix devices offer improved dc specifications over the non-A-suffix devices, such as input offset voltage. These devices combine the best features of the OP21 with highly improved slew rate and unity-gain bandwidth. 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 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 small-outline versions for high-density systems applications. These devices are characterized for operation over the full automotive temperature range of −40°C to +125°C.
