The INA239-Q1 is an ultra-precise digital power
monitor with 16-bit delta-sigma ADC specifically
designed for current-sensing applications. The device
can measure a full-scale differential input of ±163.84
mV or ±40.96 mV across a resistive shunt sense
element with common-mode voltage support from
–0.3 V to +85 V.
The low offset and gain drift design of the INA239-Q1
allows it to be used in precise systems that do not
undergo multi-temperature calibration during
manufacturing. Further, the very low offset voltage
and noise allow for use in A to kA sensing
applications and provide a wide dynamic range
without significant power dissipation losses on the
sensing shunt element. The low input bias current of
the device permits the use of larger current-sense
resistors, thus providing accurate current
measurements in the microamp range. PINA239AQDGSRQ1资料下载
