Frequently asked questions

What is the pinout of LF247DT?

The LF247DT uses the standard quad op-amp pinout for a 14-SOIC package: output 1 (pin 1), inverting input 1 (pin 2), non-inverting input 1 (pin 3), V+ (pin 4), non-inverting input 2 (pin 5), inverting input 2 (pin 6), output 2 (pin 7), output 3 (pin 8), inverting input 3 (pin 9), non-inverting input 3 (pin 10), V- (pin 11), non-inverting input 4 (pin 12), inverting input 4 (pin 13), output 4 (pin 14).

What is the gain bandwidth product of LF247DT?

The gain-bandwidth product is 4 MHz, which determines the closed-loop bandwidth for a given gain setting. For example, at a gain of 10 the usable bandwidth is approximately 400 kHz.
