I2C/SMBus INTERFACE ELECTRICAL SPECIFICATIONS

(VDD = 2.7V to 5.5V, TA = -40NC to +85NC, unless otherwise noted. Typical values are at VDD = 3.3V, TA = +25NC, unless otherwise noted.)

Note 1: All voltages are referenced to ground (VSS). Currents entering the IC are specified as positive, and currents exiting the IC

are negative.

Note 2: Only required for the MAX34440ETL+.

Note 3: This does not include pin input/output currents.

Note 4: Guaranteed by design.

Note 5: ADC has no missing codes.

Note 6: Commands MFR_MODE, STORE_DEFAULT_ALL, and RESTORE_DEFAULT_ALL require a bus free time of 250ms.
