Other Parts Discussed in Thread: LM7705
Dear TI Engineer：
I am using the OPA2836 to amplify a signal (0V~0.04V) 77 times(7*11). To get an accurate 0V voltage, whether I had to offset the amplifier's supply voltage by several hundred mV? If so, what is the minimum negative bias voltage? Is it 200mV as stated in the data sheet?
Can I use a Low-Noise Negative Bias Generator like LM7705(output -230mV) as the input of Vs-, and then use a +4.7V power supply as the Vs+ input?
