LM7705 Datasheet (Texas Instruments) - Low-Noise Negative Bias Generator

LM7705, Low-Noise Negative Bias Generator

The LM7705 device is a switched capacitor voltage inverter with a low noise, *0.23 V fixed negative voltage regulator.

This device is designed to be used with low voltage amplifiers to enable the amplifiers output to swing to zero volts.

The *0.23 V is used to supply the negative sup
