Frequently Asked Questions
1.Which operation is an upgraded version, LME49860 OP-AMP or LME49720 OP-AMP? Which is better?
LME49720 is better. It has a high conversion rate of ±20V/μs, and an output current capability of ±26mA. In addition, the output stage with maximum dynamic range drives a 2kΩ load to within 1V of any power supply voltage, and when driving a 600Ω load, it drives within 1.4V. LME49720 CMRR (120dB), PSRR (120dB) and VOS (0.1mV) make the amplifier perform excellent operational amplifier DC performance. LME49720 adopts SOIC, PDIP, TO-99 packaging process.
2.Can LM4562/LME49720/LME49722/LME49860 be directly replaced?
Yes, they can.
3.Can OPA2107 and LME49720 be interchangeable?
The two are interchangeable. The performance is good, but the style is different. It depends on you.
4.What’s the difference between LME49720 and LME49860?
The LME49720 output stage is optimized for supply voltages under +-17 volts. The LME49860 is optimized for +-14.5 to 22 volts. The LM4562 is similar to the LME49720 except it's in a metal case and has better heat dissipation and drives 600 ohms effortlessly.
