The LM346 consists of four independent, high gain, internally compensated, low power programmable amplifiers. Two external resistors (Rset) allow the user to program the gain-bandwidth product, slew rate, supply current, input bias current, input offset current, and input noise. Users can customize parameters like supply current, bandwidth, and noise figure according to their needs. The LM346 can be tailored to specific applications, offering versatility and flexibility.
Notably, the IC operates on a wide power supply range from ±1.5V to ±22V and features a class AB output stage with no crossover distortion. It also provides overload protection for inputs and outputs, ensuring stability and reliability in operation.
