Conditions/Comments
VDD = 15 V ± 5%, VREF = 10 V
Guaranteed monotonic
VDD = 14 V to 16.5 V, VREF = 10 V
Occurs when each DAC is loaded with all 1s
VREF = 10 V p-p sine wave at 10 kHz
VREF = 10 V p-p sine wave at 10 kHz
VIN = 0 V or VDD
VREF = 10 V; settling time to ±½ LSB

1 Maximum possible reference voltage.
2 Temperature range is as follows for all versions: −40°C to +85°C.
3 Sample tested at 25°C to ensure compliance.
4 Switching characteristics apply for single-supply and dual-supply operation.
