The ZXCT1008 and ZXCT1009 are the simplest of the
current monitors. The output is a current which is proportional
to the sense voltage, measured across a low value shunt
resistor, R
voltage and scaled by choice of an appropriate resistor, R
Quiescent current of only 4µA has minimal impact on system
power efficiency. Operating voltage is from 2.5V to 20V, which
makes these parts suitable for a wide range of applications.
The ZXCT1010 and ZXCT1012 have the same characteristics as
the ZXCT1009 but with a separate ground pin to avoid the
circuit current flowing through the output resistor.
This reduces the current offset and improves accuracy
particularly at lower sense voltages.
The ZXCT1012 has the same performance as the ZXCT1010
but in thinner packages.
The ZXCT1011 uses an external resistor to determine its
transconductance resulting in a much lower temperature
coefficient.
This gives a better accuracy at temperature extremes without
losing any of the parameters found in ZXCT1008/9 devices.
The ZXCT1020 uses an external resistor to set its
transconductance and allows its offset to be trimmed.
This increases the ZXCT1020 accuracy over the ZXCT1010
while maintaining the versatility of the ZXCT101.
The ZXCT1050 is the current output version of the ZXCT1051.
Two resistors are now off-chip; 1 sets the transconductance
and other sets the gain.
Its offset is trimmed improving accuracy at small sense
voltages
