Sense current amplifier with selectable gain
2
2003 Nov 10
GENERAL DESCRIPTION
The SA58780 is a single amplifier that allows current sensing
independent of the supply voltage. The input offset voltage is
typically
±
500
μ
V with typical offset drift of
±
6
μ
V/
°
C. The SA58780
supply current is typically 150
μ
A and it operates from 3.0 V to 24 V
single supply. The input common mode range is selectable for high
and low ranges. The amplifIer gain is user selected for a “High” of
100 V/V or a “Low” of 50 V/V.
The SA58780 is ideal for battery charger applications in notebook
computers and PDAs.
