^*1 Analogue output is not available within the range of -5 to +5 V.
^*2 When temperature drift correction is used, temperature drift correction time is added regardless of the number of channels used.
^*3 A/D conversion and D/A conversion are processed independently.
^*4 ±0.2 % of F.S. (0 to 50 °C) when temperature drift correction for A/D conversion is used
