Description
Reserved.
Channel I1 negative detector calculation code.
Code mapping:
7'b000-0000, Vc=-4.28mV=-3.03mVrms (Vc is the threshold of low power computation)
7'b111-1111, Vc=12.91mV=9.14mVrms
DAC typical resolution is [12.91-(-4.28)]/127=135.4µV=95.7µVrms
Reserved.
Channel I1 positive detector calculation code.
Code mapping:
7'b000-0000, Vc=-4.28mV=-3.03mVrms (Vc is the threshold of low power computation)
7'b111-1111, Vc=12.91mV=9.14mVrms
DAC typical resolution is [12.91-(-4.28)]/127=135.4µV=95.7µVrms
