VIH = VDD, VIL = GND, VDD = 3 V
1 Temperature range for the B version is 30°C to +85°C.
2 See the Terminology section.
3 Linearity is tested using a reduced code range: Code 32 to Code 1023.
4 To achieve near zero output current, use the power-down feature.
5 Guaranteed by design and characterization; not production tested. PD is active high. SDA and SCL pull-up resistors are tied to 1.8 V.
6 Input filtering on both the SCL and SDA inputs suppresses noise spikes that are less than 50 ns.
7 PD is active high. When PD is taken high, the AD5389A enters power-down mode.
