AH8500/1 & AH8502/3
AH8500/1 & AH8502/3 – Micropower Linear Hall Effect Sensor Family
with Enable/Control Pin and High Accuracy Options
The AH850/1/2/3 is a family of low
power/micropower linear hall effect
sensors with output voltage
ratiometric to supply and magnetic
field sense range of +/-400G for
battery powered consumer , home
appliances and industrial
applications.
The high performance AH8501 and
AH8503 have trimmed sensitivity
accuracy of 3% with a null voltage
offset below 1% of supply voltage.
Designed for a wide range of
applications,
they are optimized for
The Diodes’ Advantage
The AH8500/1/2/3/4 provide a high performance and low power/micropower
solutions for a wide range of applications requiring magnetic flux
measurements.
Low Voltage, Low Power Linear Halls – With Miicropower Mode
-
Supply voltage of 1.6V to 3.6V is ideal for interfacing with ADC
-
Typical current consumption of 8.9uA in sleep mode (AH8500/1), 13uA at
micropower mode (AH8502/3) and 1.16mA at 7.14kHz sampling rate.
-
Supports battery powered consumer/home appliances and industrial
applications
the supply range of 1.6V to 3.6V
consuming only 8.9uA in sleep
mode (AH8500/AH8501) and 13uA
in micropower mode
(AH8502/AH8503).
The sensors have a ESD rating of
6kV for robustness.
For system flexibility the enable pin
in the AH8500/1 and CNTRL pin on
the the AH8502/3 allow operating
modes and sampling rate to
minimize current consumption. In
default modes, the AH8500/1 are in
sleep mode while AH8502/3 operate
in micropower mode.
High Sensitivity with High Accuracy (Trimmed) Options
-
High accuracy AH8501/3 have a sensitivity of 2.25mV/G and 3.8mV/G at 1.8V
and 3V respectively with accuracy of 3% at 25
