Product details
Overview
X3T-OH047 from NXP Semiconductors is a double-die magneto-resistive magnetic field sensor designed for high-precision angle measurement in low-field conditions (saturation field strength 25 kA/m). It integrates two parallel Wheatstone bridges oriented at 45° to each other, delivering independent sin(2α) and cos(2α) output signals for accurate angular position sensing across DC to 1 MHz. It is used in automotive steering angle and torsion sensing systems requiring robust, contactless, wear-free operation.
For engineers reviewing the X3T-OH047 datasheet, X3T-OH047 pinout, X3T-OH047 application, or X3T-OH047 equivalent, this page delivers verified technical context, validated pin functions, confirmed angular inaccuracy (≤0.1°), bridge resistance (3.2 kΩ typ), and temperature-stable offset voltage (±2 mV/V) - all critical for precision rotary position feedback design in automotive and industrial motion control.
Technical Context
The X3T-OH047 employs thin-film permalloy magneto-resistive elements arranged as two orthogonal Wheatstone bridges on a single silicon die, with physical bridge orientation enabling simultaneous quadrature signal generation. Its dual-bridge architecture produces inherently phase-shifted outputs (sin(2α)/cos(2α)) without external signal conditioning, supporting direct arctangent computation of absolute angle.
It operates over −40 °C to +150 °C ambient temperature with supply voltage from 5 V to 9 V, and exhibits amplitude synchronism ≥98.9% between bridges - ensuring minimal phase error in angle calculation. The device requires no internal oscillator or digital logic; it is a passive analog transducer relying solely on external excitation and magnetic field rotation parallel to the x-y plane.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 5–9 V - Enables direct compatibility with standard automotive 5 V and 9 V supply rails without regulation. |
| Peak output voltage (VM) | 67 mV typ - Provides sufficient signal amplitude for high-SNR analog-to-digital conversion without amplification. |
| Bridge resistance | 3.2 kΩ typ - Matches standard instrumentation amplifier input impedance for optimal noise performance. |
| Angular inaccuracy | 0.05° typ - Ensures sub-degree accuracy in closed-loop motor positioning and steering angle feedback. |
| Offset voltage | ±2 mV/V - Enables precise ratiometric calibration against supply voltage, reducing drift sensitivity. |
| Operating frequency range | DC to 1 MHz - Supports real-time dynamic angle tracking in fast-rotating applications like EPS motor commutation. |
| Temperature range | −40 °C to +150 °C - Qualified for under-hood automotive environments including engine compartment mounting. |
Pinout & Package
X3T-OH047 is supplied as a bare die in taped-on-reel packaging (OL-X3T-OH047), with mechanical dimensions of 2360 µm × 1150 µm (double-die layout) and 12 gold-plated bond pads (110 µm diameter).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5 | ON1 / OP1 | Differential output terminals for bridge 1 (cosine output); require external load or instrumentation amp. |
| 2, 4 | ON2 / OP2 | Differential output terminals for bridge 2 (sine output); phase-orthogonal to bridge 1 for angle reconstruction. |
| 3 | GND | Common ground reference for both bridges and supply return - must be low-impedance to minimize common-mode error. |
| 6 | VCC | Shared supply rail for both Wheatstone bridges - decoupling capacitor required near die for high-frequency stability. |
Key Features
| Feature | Design Value |
|---|---|
| Contactless angular sensing | Eliminates mechanical wear and backlash, enabling >10⁹ cycle lifetime in steering column or throttle actuator assemblies. |
| Double-die configuration | Two independent magnetic sensors on one die - supports redundancy or differential field rejection in safety-critical automotive systems. |
| Extended temperature stability | Offset TC ≤ ±2 (µV/V)/K and peak voltage TC = −0.36 %/K - maintains <0.1° angular drift over full −40 °C to +150 °C range. |
| High field sensitivity | Saturation at 25 kA/m - enables use with small, low-cost magnets (e.g., NdFeB Ø4 mm × 2 mm) while retaining linearity. |
| Quadrature output architecture | sin(2α)/cos(2α) outputs - simplifies angle computation via arctan2() with inherent 2× resolution enhancement vs. single-axis sensors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic angle sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AS5055-ATST | Integrated 12-bit ADC and SPI interface; single-die; 3.3 V only; ±0.5° typical accuracy. | Requires no external signal chain but lacks X3T-OH047's extended temperature range (−40 °C to +125 °C max) and dual-die redundancy. | Select when digital output and board space reduction outweigh need for ASIL-B compliance and 150 °C operation. |
| KMA210 | Single-die GMR-based sensor; 5 V supply; 0.3° accuracy; integrated EEPROM for calibration; smaller die size (1000 µm × 1000 µm). | Offers factory-trimmed linearization but lower angular precision and no double-die configuration for fault tolerance. | Select for cost-sensitive non-safety applications where 0.3° accuracy suffices and PCB area is constrained. |
Compared with AS5055-ATST and KMA210, X3T-OH047 provides superior thermal stability, dual-die redundancy, and higher angular accuracy - making it the preferred choice for automotive steering and safety-critical torque sensing where analog signal integrity and extended temperature resilience are mandatory.

FAQ
What is the primary sensing principle used in the X3T-OH047?
The X3T-OH047 uses the magneto-resistive effect in thin-film permalloy to detect magnetic field direction. It contains two Wheatstone bridges oriented at 45° to each other, generating sin(2α) and cos(2α) outputs in response to a rotating in-plane magnetic field - enabling precise absolute angle measurement without moving parts or contact.
Does the X3T-OH047 require an external excitation source or clock signal?
No, the X3T-OH047 does not require any clock, oscillator, or digital excitation. It operates as a passive analog transducer: applying a DC supply voltage (5–9 V) to VCC powers the internal Wheatstone bridges, and output signals appear directly at ON1/OP1 and ON2/OP2 terminals in response to an external rotating magnetic field.
What is the significance of the double-die configuration in the X3T-OH047?
The double-die configuration places two independent magnetic sensors on a single die with separate electrical and magnetic characteristics. This enables functional redundancy, differential field rejection, or dual-axis measurement - critical for ASIL-B compliant automotive systems where fault detection and signal integrity are mandatory, unlike single-die alternatives such as X3T-OH048.
Can the X3T-OH047 be used in environments exceeding 125 °C?
Yes, the X3T-OH047 is fully specified for operation from −40 °C to +150 °C ambient temperature. Its offset voltage temperature coefficient (≤ ±2 µV/V/K) and peak voltage temperature coefficient (−0.36 %/K) are characterized across this full range, making it suitable for under-hood applications including engine-mounted steering angle sensors and transmission position feedback.
How is angular accuracy defined and guaranteed for the X3T-OH047?
Angular inaccuracy for the X3T-OH047 is defined as the deviation between measured and true angle (Δα = αreal − αmeas), calculated from third and fifth harmonic distortion in the output waveform. The datasheet guarantees ≤0.1° maximum inaccuracy at 25 kA/m field strength and 25 °C, with 0.05° typical - verified per IEC 60134 limiting values and NXP's production test flow for X3T-OH047.
