AKM Linear Hall Effect IC Magnetic Sensors
 |
| |
AKM (Asahi) Linear Hall Effect IC Magnetic Sensors consist of a Hall Element and an Amplifer in a package. The sensors detect the magnetic field and generate an very small analog output signal proportional to the magnetic field. AKM offers 4 levels of sensitivities in the SMT (SOP) versions and 1 lead in the SIP version.
The AKM non-programmable linear sensors offer a significant improvement in single axis linear Hall Effect sensing. Compared with
other popular linear sensors on the market, the AKM linear sensor EQ-711L, has:

The AKM EQ-711L (SIP) sensor is ideal for slotted core open and closed loop current sensors. With significantly lower noise, the dynamic range will
be significantly improved. The thin package enables a reduced core gap to increase the sensitivity and reduce the fringe field near the gap. The enhanced badnwidth increases
the AC response by a factor of greater than 2.
Because of the very low noise level, the EQ sensors are also ideal for linear and angular sensing applications in the DC to 100kHz
range.
