Magnetic Angle Encoder Chip
CONNTEK's magnetic linear angle encoder IC integrates a HALL sensing element and a dedicated decoding processing chip, which can achieve angle detection accuracy within +/- 1°; the minimum 4mm*4mm package can meet the small size requirements of most applications. At the same time, the non-contact magnetic induction control has high reliability, and the applicable maximum temperature range is -40~125℃. It has traditional ABZ/UVW incremental output, analog output, and I2C, SPI, PWM and other output interfaces.
High-Speed High-Resolution Magnetic Coded Angle Sensor
KTH78xx series is a high-precision, low-latency 16-bit resolution Hall absolute angle encoder capable of measuring magnetic field components in the XY plane. This sensor supports four-wire SPI absolute angle output (optional CRC output verification), two-wire SSI absolute angle output, programmable 4-4096 steps/revolution ABZ incremental output, programmable 1-8 pole pairs UVW incremental output, and PWM duty cycle angle output. The chip integrates an alarm function, allowing users to customize alarm thresholds for low or high magnetic field conditions.
Linear Hall Chip
Linear Hall-effect sensors respond proportional to the magnetic flux density. The chip can be widely used in systems for precise position sensing. The chip operating voltage range is 3.3~5V. When there is no magnetic field input, the output of the driver stage is half of VCC. The output voltage has a linear relationship with the input magnetic flux density, and the output voltage range has five options according to the input sensing range.
Micro-power Series
KTH16XX series products use CMOS technology and integrate Hall sensing elements in the chip. This series of chips has a working voltage of 1.7~5.5V, ultra-low power consumption of 1μA, and excellent temperature compensation, so that the chip can work in the environment of -40~125℃, and maintain good performance and consistency.
Magnetoresistive Switch Series
KTM13XX series products are integrated in a single chip with TMR bridge and ASIC whose impedance value changes according to the strength and angle of the parallel passing magnetic field. By cooperating with a magnet, non-contact position detection is performed. Compared with the Hall sensor, it has higher precision (the hysteresis can be less than 3 Gauss), the parallel induction of the magnetic field, and the TMR bridge resistance in different directions to achieve 360-degree two-dimensional sensing characteristics. It is mainly used in applications with different sensing angles and low power consumption and high frequency sensing.
Automotive High-Voltage Digital-Latch Hall Effect Sensor
KTH25XX utilizes advanced PWM (Pulse-Width Modulation) technology with a built-in zero-drift amplifier and integrated temperature compensation circuitry. It has an offset voltage of less than 10µV and very low offset drift characteristics with excellent sensitivity and temperature stability over the operating temperature range. Its open-drain output stage supports a high drive capability of up to 30mA, along with reverse load capability and output short-circuit overcurrent protection. With a wide supply voltage range of 2.7 to 32 V and available in SOT-23-3L and TO-92S packages, it offers a reverse protection voltage of up to -32 V, making it suitable for a wide range of automotive and industrial applications.
Micro-power CMOS Operational Zero-drift Amplifier Chip
KTAx333 is a low-offset, low power consumption, CMOS operational amplifier with rail-to-rail input and output. It utilizes self-calibration technology to provide extremely low offset voltage (2μV, typical value). The KTAx333 series offers excellent Common-Mode Rejection Ratio (CMRR) performance without the crosstalk associated with traditional complementary input stages. This design allows for exceptional performance during driving of Analog-to-Digital Converters (ADCs) without compromising differential linearity. These features make KTAx333 highly suitable for amplifying signals from various types of sensors.
