High Precision, Output Pin Programmable, Linear Hall Effect Sensors A1373 and A1374 CHARACTERISTIC PARAMETERS (continued) SENSITIVITY TEMPERATURE COEFFICIENT PROGRAMMING over operating temperature range, VCC=5.0 V, unless otherwise noted Sensitivity Temperature Coefficient Range TC Sensitivity T/C codes 0 to 11, minimum (absolute) positive temperature coefficient attainable – 0.07 – %/°C Sensitivity T/C codes 16 to 27, minimum (absolute) negative temperature coefficient attainable – – 0.016 – %/°C Average Sensitivity Temperature Coefficient Step Size4,5,6 StepTC TA = 150°C – 0.01 – %/°C Sensitivity Temperature Coefficient Programming Bits –– 5 – Bit ONE-TIME PROGRAMMING Device Programming Lock Bit – – 1 – Bit RATIOMETRY over operating temperature range, VCC=5.0 V, unless otherwise noted Quiescent Voltage Error RatVOUT(Q) VCC at VOPERATING – ±0.25 –% Sensitivity Error RatSENS VCC at VOPERATING – ±1.0 –% Clamp Error RatVOUTCLP VCC at VOPERATING – ±1.5 –% LINEARITY over operating temperature range, VCC=5.0 V, unless otherwise noted Positive Linearity Error Lin+ VCC at VOPERATING – ±0.5 –% Negative Linearity Error Lin– VCC at VOPERATING – ±0.5 –% SYMMETRY over operating temperature range, VCC=5.0 V, unless otherwise noted Symmetry Error Sym VCC at VOPERATING – VCC – ±0.35 – % ADDITIONAL CHARACTERISTICS Sensitivity Drift9 ΔSens – – ±2 % FAULT CONDITIONS over operating temperature range, VCC=5.0 V, unless otherwise noted Shorted Output Wire IOUTSHT VOUT pin to VCC pin – – 18 mA VOUT pin to GND pin – – 4 mA 1 tPO does not include tCLP, specified in the Quiescent Programming section of this table. 2 Peak to peak value exceeded: 0.3% (6σ). 3 For A1373, no digital noise is present at the output. 4 Step size is larger than required for the specified range, to take into account manufacturing spread. 5 Individual code step sizes can be greater than 2× larger than the step size at each significant bit rollover. 6 Average fine code step size in a given range = (Output value at highest fine code in the range – Output value at code 0 of the range) / Total quantity of steps (codes) in the range. 7 Values indicated are valid if any additional magnetic field does not exceed B(kG)= ±2 (V) / Sens (mv/G), after VOUTCLP is reached. 8 Program the Sensitivity T/C register before programming Sensitivity Coarse and Sensitivity Fine, due to a worst case shift of ±3% in sensitivity at 25°C at the maximum values for Sensitivity T/C: Positive T/C and Sensitivity T/C: Negative T/C. The Programming Guidelines section in this document lists a complete recommended order for programming individual values. 9Drift due to temperature cycling is due to package effects on the Hall transducer. The stress is reduced when the package is baked. However, it will recover over time after removal from the bake. Characteristic Symbol Test Conditions Min. Typ. Max Units |
