Table 26.14 lists the D/A conversion characteristics.

Table 26.14 D/A Conversion Characteristics

Condition A: V

CC = 5.0 V ±10%, AVCC = 5.0 V ±10%, AVref = 4.5 V to AVCC,

SS = AVSS = 0 V, φ = 2 MHz to maximum operating frequency,

a = –20 to +75°C (regular specifications),

a = –40 to +85°C (wide-range specifications)

Condition B: V

CC = 4.0 V to 5.5 V, AVCC = 4.0 V to 5.5 V, AVref = 4.0 V to AVCC,

SS = AVSS = 0 V, φ = 2 MHz to maximum operating frequency,

a = –20 to +75°C (regular specifications),

a = –40 to +85°C (wide-range specifications)

Condition C: V

CC = 3.0 V to 5.5 V, AVCC = 3.0 V to 5.5 V, AVref = 3.0 V to AVCC,

SS = AVSS = 0 V, φ = 2 MHz to maximum operating frequency,

a = –20 to +75°C
