1. TS272AIDT Substitution Conclusion
The TS272AIDT outperforms the TLC252CD in most key specifications, including higher slew rate (5.5 V/µs vs. 2.9 V/µs), wider gain-bandwidth product (3.5 MHz vs. 2.2 MHz), lower quiescent current (1 mA vs. 1.9 mA), and lower input offset voltage (900 µV vs. 1.1 mV), while offering significantly stronger output drive capability (45 mA). Its minimum operating supply voltage is 3 V, compared to 1.4 V for the TLC252CD, which prevents direct substitution if the original design operates below 3 V. Additionally, its input bias current is slightly higher (1 pA vs. 0.6 pA), which may introduce minor errors in applications with ultra-high-impedance signal sources. Provided the system supply voltage is ≥3 V and does not rely on extremely low input bias current, the TS272AIDT can be considered a performance‑upgrade replacement.
2. TS272BIDT Substitution Conclusion
The TS272BIDT shares the same advantages in speed, bandwidth, power consumption, and output drive as the TS272AIDT, while its input offset voltage is further reduced to 250 µV—an improvement of more than 4× over the original part. This significantly lowers system error in precision DC amplification or sensor signal conditioning. However, it is similarly limited by a 3 V minimum supply requirement and cannot cover the TLC252CD’s ultra‑low‑voltage applications down to 1.4 V; its input bias current (1 pA) remains slightly higher than the original device. For applications with a supply voltage ≥3 V and higher accuracy requirements, the TS272BIDT is not only a valid substitute but also provides a comprehensive upgrade in precision and dynamic performance, making it particularly suitable for designs sensitive to offset voltage.
