(3) For best accuracy, minimize output loading. 10k pull-ups resistors should be sufficient. Higher sink currents can affect sensor accuracy
with internal heating. This can cause an error of 0.64 癈 at full rated sink current and saturation voltage based on junction-to-ambient
thermal resistance.

(1) Typical values are at T
A
= 25 癈 and represent most likely parametric norm.
(2) Limits are guaranteed to TI's AOQL (Average Outgoing Quality Level).
(3) Timing specifications are tested at the bus input logic levels (Vin(0)=0.3xVA for a falling edge and Vin(1)=0.7xVA for a rising edge) when
the SCL and SDA edge rates are similar.
(4) Holding the SDA and/or SCL lines Low for a time interval greater than t
TIMEOUT
will cause the LM92 to reset SCL and SDA to the IDLE
state of the serial bus communication (SDA and SCL set High).
