LM346 is a low power, programmable four-channel amplifier with low input bias current, low noise voltage, wide power supply voltage range
This document is a datasheet for the LM146, LM246, and LM346, which are programmable quad bipolar operational amplifiers. The devices consist of four independent, high-gain, internally compensated amplifiers that allow users to tailor characteristics such as gain-bandwidth product, slew rate, and supply current using two external resistors.
| Supply Current (Iset = 10µA) | 1mA |
|---|---|
| Gain Bandwidth Product (Iset = 10µA) | 1MHz |
| Large DC Voltage Gain | 120dB |
| Low Noise Voltage | 28nV/√Hz |
| Supply Voltage Range | ±1.5V to ±22V |
| Output Stage Class | Class AB |
| Slew Rate (Typ) | 0.5V/µs |
| Input Bias Current (Typ) | 30nA |
| Operating Temperature (LM346) | 0°C to +70°C |
Two external resistors (Rset) allow the user to program the gain-bandwidth product, slew rate, supply current, and other characteristics.
The absolute maximum supply voltage rating is ±22V.
Yes, any output can be shorted to ground indefinitely, but more than one should not be shorted simultaneously.
