AD976A's Transfer function

Question I am unsure about the transfer characteristic of the AD976/AD976A shown in page 10 of the datasheet. The analog input range is -10V-10V and reference voltage is 2.5V, the transfer function should be that shown (table 1 in attachment). Answer The full-scale range (FSR) of the AD976A is equal to ±4 VREF (VREF=2.5V), so the with a ± 10 V input, one LSB is 305 µV. The AD976A transfer characteristics on page 10 can be shown as below (table 2 in attachment).
