= -40 to +85 °C; V1+ = V2+ = +2.5 V, ±5%; V1- = V2- = -2.5 V, ±5%;
VL - VLR = 3.3 V, ±5%, 2.5 V, ±5%, or 1.8 V, ±5%
Input levels: Logic 0 = 0V Low; Logic 1 = VD+ = High; CL = 15 pF.
11.
SDO and SCLK will be high impedance when CS is high. In some systems it may require a pull-down resistor.
12.
SCLK = MCLK/2.
