1. OP282GSZ Substitution Conclusion From a technical parameter comparison, the OP282GSZ outperforms the original TLE2061MD in slew rate (9 V/µs vs. 3.4 V/µs), gain-bandwidth product (4 MHz vs. 2 MHz), input bias current (3 pA vs. 4 pA), and input offset voltage (200 µV vs. 600 µV). This provides superior performance for high-frequency signal processing, DC precision, and low-power applications. However, its output current capability is lower (10 mA vs. 80 mA), resulting in weaker drive capability for heavy loads, which may make it unsuitable for high-current output applications. Furthermore, its minimum supply voltage is higher (9 V vs. 7 V), limiting its use in low-voltage scenarios. Additionally, the OP282GSZ is a dual-channel amplifier, whereas the TLE2061MD is a single-channel device, leading to pinout incompatibility. Direct substitution would require a PCB layout redesign. In summary, if the application does not require high output current or operation below 9 V, and a pinout redesign is acceptable, the OP282GSZ can replace the TLE2061MD and offer performance improvements. Otherwise, the substitution is not feasible.
