  • Product introduction

The A1340 device is a highly accurate programmable device for automotive and non-automotive applicationsHall-effect linear sensorsIntegrated circuits (ICs). The signal path of the A1340 provides flexibility through external programming that ensures accurate and customized output voltages from the input magnetic signals. The A1340 provides 12-bit output resolution and supports bandwidths up to 3 kHz.

BiCMOS monolithic integrated circuits contain:Hall sensorElement, high-precision temperature compensation circuitry to reduce the inherent sensitivity and offset drift of Hall elements, small signal high-gain amplifier, proprietary dynamic offset cancellation circuitry, and advanced output linearization circuitry.

With on-board EEPROM and advanced signal processing, the A1340 offers unmatched customer-programmable options for gain and offset, bandwidth, and output clamping. Multiple input magnetic ranges and signal offset options can be factory preset. In addition, the device supports separate high and low temperature, first- and second-order temperature compensation.

A key feature of the A1340 is its ability to generate a highly linear device output in a nonlinear input magnetic field. To achieve this, the device divides the output into 32 equal segments and applies a unique linearization factor to each segment. The linearization coefficients are stored in EEPROM's lookup table.

The A1340 sensor is available in a lead-free (Pb) 4-pin single in-line package (KT suffix) with 100% matte tin leadframe plating.

  • Advanced 32-band output linearization provides extremely high output accuracy and linearity even in the presence of a nonlinear input magnetic field
  • Sensitivity and offset, bandwidth, output clamping, and first- and second-order temperature compensation are adjustable
  • All parameters can be programmed simultaneously for accurate and efficient system optimization
  • The magnetic input range (coarse sensitivity) and signal offset have been factory adjusted
  • Sensitivity temperature coefficient and magnetic offset drift can be preset in Allegro for maximum device accuracy without customer temperature testing
  • Proprietary four-phase chopper stabilization and differential circuit design techniques are used to obtain temperature-stable, mechanically stress-resistant, and very low-noise device outputs
  • Provides open-circuit and undervoltage diagnostics
  • Wide ambient temperature range: –40°C to 150°C
  • The supply voltage is 4.5 to 5.5 V
