The maximum power dissipation of the MC1458PSR is 670mW, which is calculated based on the maximum junction temperature (TJ) of 150°C and the thermal resistance (RθJA) of 125°C/W.
While the MC1458PSR is an op-amp, it can be used as a comparator in certain applications. However, it's not recommended for high-speed or high-precision comparator applications due to its limited slew rate and bandwidth.
The input impedance of the MC1458PSR is typically around 2MΩ, but it can vary depending on the specific application and operating conditions.
Yes, the MC1458PSR can be used in a single-supply configuration, but it's essential to ensure that the input common-mode voltage range is within the specified limits to maintain proper operation.
The output current capability of the MC1458PSR is typically around 20mA, but it can be limited by the output impedance and the load resistance.
