A minus sign (–) prefixing a current value indicates that the current flows from the IC to the external circuit.
*1: Conversion error: For all channels, deviation from a straight line between two points obtained by channel
addresses 000 (0 scale) and 111 (full scale).
*2: Linearity error; Deviation from a straight line between the 0 and full scale points for each channel.
*3: Crosstalk between channels: Voltage change VCH of CH terminal occurring when an input voltage of a channel
is changed by ∆V1 while another channel is already charged (RAMP START = 0).
This calculated by 20log ^∆VCH
∆V1
*4: Acquisition time: Sum of multiplexer delay time, RAMP START delay time, and time required to charge the
selected input voltage to the ramp capacitor.
