5 / 37 page LM4936 www.ti.com SNAS269A – APRIL 2005 – REVISED APRIL 2013 Electrical Characteristics for Control Interface (1) (2) The following specifications apply for VDD = 5V, VDD = 3V and 2.4V ≤ I 2C/SPI V DD ≤ 5.5V. Limits apply for TA = 25°C.

All specifications are tested using the typical application as shown in Figure 2. (2) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is functional, but do not ensure specific performance limits. Electrical Characteristics state DC and AC electrical specifications under particular test conditions which ensure specific performance limits. This assumes that the device is within the Operating Ratings. Specifications are not specified for parameters where no limit is given, however, the typical value is a good indication of device performance. (3) Typicals are measured at 25°C and represent the parametric norm. (4) Limits are specified to Texas Instruments' AOQL ( Average Outgoing Quality Level). Datasheet min/max specification limits are specified by design, test, or statistical analysis. Electrical Characteristics for Single-Ended Mode Operation (1) (2) The following specifications apply for VDD = 5V. Limits apply for TA = 25°C.
