I want to make a low-pass Butterworth filter with a passband of 10M, what type of op-amp should I use and at a lower price, thanks!

The signal you want to process has a high frequency, so you should use a high-speed broadband op amp. The commonly used op-amps are AD8052, OP37 and LM4562. Here we recommend that you use the LM4562, which has a wide operating voltage range and high precision.

LM4562 is a high-fidelity dual op amp introduced by National Semiconductor in recent years, its distortion is ultra-small, only 0.00003% of the total harmonic distortion and noise (THD + N), in other words, the distortion of this op amp is almost negligible.

The LM4562 chip features extremely low distortion, low noise, high slew rate, a wide operating voltage range, and high output current for unprecedented performance. Because of these advantages, this operational amplifier is suitable for professional-grade and high-end audio systems, such as audio/video system receivers, preamplifiers, audio decoders and hi-fi amplifiers, as well as various medical imaging systems and industrial equipment.

The LM4562 chipset is uniquely designed with a high-speed 6MHz unity-gain bandwidth operational amplifier and a proprietary stereo audio driver amplifier. In standard operation, the op amp has an input noise density as low as 2.7nV/√Hz, a midrange noise corner of 60Hz, and an output current of 26mA to drive a 600Ω load. The LM4562 features a slew rate of 20V/μs and a gain bandwidth of 55MHz.

The LM4562 chipset can be configured to operate in either ±2.5V or ±2.5Mbps, with a maximum of 1.5Gbps. The LM4562 can operate over a supply voltage range of ±2.5V to ±17V with a maximum output current of 45mA. When operating over this voltage range, the chip's input circuitry achieves a ****-mode rejection ratio (CMRR) and power supply rejection ratio (PSRR) of more than 108dB, while the input bias current is as low as 10μA (typical).

The AD8052 is a low voltage, high speed, wide bandwidth, full amplitude op amp (dual op amp) that operates at 3~12V and has a gain bandwidth product of up to 110MHz. with a conversion rate of up to 145V/us. it is well suited to your requirements.
