1. TS272BIDT Substitution Conclusion
The TS272BIDT offers superior performance compared to the original part, featuring higher precision (input offset voltage of 250 µV vs. 900 µV), faster response (slew rate of 5.5 V/µs vs. 2.9 V/µs, gain bandwidth product of 3.5 MHz vs. 2.2 MHz), and lower quiescent current (1 mA per channel vs. 1.9 mA). It is therefore suitable for applications with stricter requirements for accuracy, bandwidth, and power consumption. Its primary limitation is a minimum supply voltage of 3V, whereas the original part can operate down to 1.4V. Consequently, the TS272BIDT cannot be used in low-voltage systems operating between 1.4V and 3V. In designs with a supply voltage ≥3V that do not rely on extremely low-voltage operation, it can serve as a direct replacement, delivering enhanced performance.
2. TS27L2ACDT Substitution Conclusion
The TS27L2ACDT is an ultra-low-power variant, with a quiescent current of only 10 µA per channel, significantly lower than the original part's 1.9 mA. This makes it suitable for battery-powered, extremely low-power applications. However, its bandwidth (gain bandwidth product of 100 kHz) and slew rate (0.04 V/µs) are substantially lower than those of the original part (2.2 MHz, 2.9 V/µs). It cannot process higher-frequency or fast-changing signals. Furthermore, its minimum operating voltage is 3V (the original part supports down to 1.4V). Substitution should only be considered when the application is extremely power-sensitive, the signal frequency is very low (≤100 kHz), and the operating voltage is ≥3V. Otherwise, the performance gap may lead to signal distortion or inadequate response.
