The LM307 is an obsolete operational amplifier (op-amp) designed for general-purpose applications. It's part of a series that includes the LM107 (military temperature grade) and LM207 (industrial temperature grade). While still available from some distributors, newer op-amps offer better performance and features.
Here's a breakdown of the LM307's key characteristics:
Type: General-purpose Operational Amplifier
Function: Amplifies the difference between two input voltages (differential gain). Can be configured for various applications like inverting amplifiers, non-inverting amplifiers, voltage followers, and more.
Supply Voltage: Wide operating range, typically ±15V (dual power supply) or from 0°C to 70°C (single supply with limitations).
Gain: High open-loop voltage gain (typically in the hundreds of thousands).
Benefits:
Wide Supply Voltage Range: Offers flexibility in power supply choices.
Frequency Compensation: Internally compensated, simplifying design compared to externally compensated op-amps like the LM301.
Limitations:
Lower Bandwidth: Compared to some modern op-amps, the LM307 might have a lower bandwidth (typically in the 1 MHz range).
Higher Input Offset Voltage: Input offset voltage may be higher than some specialized op-amps, potentially introducing errors in some circuits.
Obsolete: Newer op-amps offer improved performance and features.
