VCM1193L
Three-Axis Magnetic Sensor
1 Product Overview
The VCM1193L is a three-axis magnetic sensor with very
low power consumption developed specifically for Drone
Nevigation. This surface-mount, small sized chip has
integrated magnetic sensors with signal condition ASIC, it
offers the advantages of low noise, high accuracy, low power
consumption, offset cancellation.
The VCM1193L is based on Anisotropic Magneto-
Resistive (AMR) and CMOS technology, Linear three axis
magnetic sensor along with custom-designed 16-bit ADC and
power management ASIC, it provides digital signal with I²C
serial bus.
The VCM1193L is in a 3x3x0.9mm3 surface mount 16-pin
land grid array (LGA) package.
