Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.

Note 1:
All devices are 100% production tested at T
A
= +25°C and are guaranteed by design for T
A
= -40°C to +85°C as specified.
Note 2:
Typical value only, set-point input voltage range determined by logarithmic slope and logarithmic intercept.
Note 3:
Set-point slew rate is the rate at which the reference level voltage, applied to the inverting input of the g
m
stage, responds
to a voltage step at the SET pin (see Figure 1).
Note 4:
Typical min/max range for detector.
Note 5:

三星刚出的旗舰新机Galaxy S III固然不错，但是高昂的价格不是每个人都能承受的起。昨天我们报道了一部山寨版的i9300，而现在该机价格和具体配置已经全部出炉。 这款山寨的Galaxy S III名叫HDC Galaxy S3，其外形甚至UI界面都与原型机异常相似。该机的三围为138×70×9.2mm，配备了一块4.7寸触摸屏，分辨率只有800×480像素。
该机还搭载了...[详细]
