SC310ASKTR
The SC310 is a high-side current sense amplifier ideal for
any application where precision current monitoring is
needed. Possible uses include battery-powered products
such as cellphones and notebooks, as well as industrial
and data acquisition applications. The wide 2.7V to 25V
common mode input range is independent of supply range,
providing complete flexibility in battery sensing applica-
tions.
The Current-Sense Amplifier offers three gain versions,
SC310A (gain 20 V/V), SC310B (gain 50 V/V) and
SC310C (gain 100 V/V). An external shutdown pin
(SHDN) enables turn off for the IC. A buffered output
with low impedance renders the overall gain immune to
load resistance. Output range is from 0V to Vcc - 1.7V.
Other features include tiny SOT-23-6 packaging, very low
supply current, and wide supply voltage range (3V to 25V).
The SC310 is rated for operation over the Industrial Tem-
perature range (-40°C to +125°C).
