LSB = 10.24/1024.
= 0.01v.
= 10 mv.
ACCURACY = 10 mv/2.
= 5 mv.
TEMP COEFF = 5 mv/25.
= 0.2 mv/C.
= 200 μV/°C.
= 0.01v.
= 10 mv.
ACCURACY = 10 mv/2.
= 5 mv.
TEMP COEFF = 5 mv/25.
= 0.2 mv/C.
= 200 μV/°C.

LSB=(OUTPUT VOLTAGE)/2^n.
Accuracy given,
LSB/2.
TEMP. COEFF.=ACC./ temp.
Accuracy given,
LSB/2.
