General Description
The MAX9922/MAX9923 ultra-precision, high-side cur-
rent-sense amplifiers feature ultra-low offset voltage
(VOS) of 25V (max) and laser-trimmed gain accuracy
better than 0.5%. The combination of low VOS and high-
gain accuracy allows precise current measurements
even at very small sense voltages.
The MAX9922/MAX9923 are capable of both unidirec-
tional and bidirectional operation. For unidirectional
operation, connect REF to GND. For bidirectional oper-
ation, connect REF to VDD/2.
The MAX9922 has adjustable gain set with two external
resistors. The MAX9923T/MAX9923H/MAX9923F use an
internal laser-trimmed resistor for fixed gain of 25V/V,
100V/V, and 250V/V, respectively. The devices operate
from a +2.85V to +5.5V single supply, independent
of the input common-mode voltage, and draw only 700A
operating supply current and less than 1A in shutdown.
The +1.9V to +28V current-sense input common-mode
voltage range makes the MAX9922/MAX9923 ideal for
current monitoring in applications where high accuracy,
large common-mode measurement range, and mini-
mum full-scale VSENSE voltage is critical.
The MAX9922/MAX9923 use a spread-spectrum
autozeroing technique that constantly measures and
cancels the input offset voltage, eliminating drift over
time and temperature, and the effect of 1/f noise. This,
in conjunction with the indirect current-feedback tech-
nique, achieves less than 25V (max) offset voltage.
The MAX9922/MAX9923 are available in a small 10-pin
MAX package and are specified over the -40°C to
+85°C extended temperature range.
