SENSOR PRODUCTS
1, 2 AND 3-AXIS MAGNETIC SENSORS
x Miniature Surface-Mount Packages x Wide Field Range of ± 6 Gauss
x 1.0 mV/V/gauss Sensitivity
x Low Power Operation Down to 1.8V
x Patented On-chip Set/Reset and Offset Straps
Product Description
The Honeywell HMC1051, HMC1052 and HMC1053 are high performance magnetoresistive sensor designs on a single chip (HMC1051, HMC1052) or two chips (HMC1053). The advantages of these patented chips include orthogonal two-axis sensing (HMC1052), ultra small size and low cost in miniature surface mount packages.
Each of the magneto-resistive sensors are configured as a 4-element wheatstone bridge to convert magnetic fields to differential output voltages. Capable of sensing fields down to 120 micro-gauss, these sensors offer a compact, high sensitivity and highly reliable solution for low field magnetic sensing.
