A1301 and A1302

Continuous-Time Ratiometric Linear Hall Effect Sensors

Characteristic Definitions

Ratiometric. The A1301 and A1302 feature a ratiometric

output. This means that the quiescent voltage output, V_OUTQ

and the magnetic sensitivity, Sens, are proportional to the supply

voltage, V_CC

Quiescent Output Voltage. In the quiescent state (no sig-

nificant magnetic field: B = 0), the output, V_OUTQ, equals one

half of the supply voltage, V_CC, throughout the entire operating

ranges of V_CCand ambient temperature, T_A. Due to internal

component tolerances and thermal considerations, however,

The ratiometric change (%) in the quiescent voltage output is

defined as:

there is a tolerance on the quiescent output voltage, ∆V_OUTQ

which is a function of both ∆V_CCand ∆T_A. For purposes of speci-

fication, the quiescent output voltage as a function of tempera-

ture, ∆V_{OUTQ(∆T )}, is defined as:

where Sens is in mV/G, and the result is the device equivalent

accuracy, in gauss (G), applicable over the entire operating tem-

perature range.

Linearity and Symmetry. The on-chip output stage is

Sensitivity. The presence of a south-polarity (+B) magnetic

field, perpendicular to the branded face of the device package,

increases the output voltage, V_OUT, in proportion to the magnetic

field applied, from V_OUTQtoward the V_CCrail. Conversely, the

application of a north polarity (–B) magnetic field, in the same

orientation, proportionally decreases the output voltage from its

quiescent value. This proportionality is specified as the magnetic

sensitivity of the device and is defined as:

designed to provide linear output at a supply voltage of 5 V.

Although the application of very high magnetic fields does not

damage these devices, it does force their output into a nonlinear

region. Linearity in percent is measured and defined as:
