Product details
Overview
X3G-OH048,005 from NXP Semiconductors is a single-die magneto-resistive magnetic field sensor employing thin-film permalloy Wheatstone bridges at 45° relative orientation. It delivers independent cos(2α) and sin(2α) output signals for high-precision angle measurement under low-field conditions (25 kA/m saturation), operates from DC to 1 MHz, and features 67 mV typical peak output voltage with ±0.1° angular inaccuracy at 25 °C.
For engineers reviewing the X3G-OH048,005 datasheet, X3G-OH048,005 pinout, X3G-OH048,005 application, or X3G-OH048,005 equivalent, this page provides verified technical context, validated pin functions, confirmed operating parameters across −40 °C to +150 °C, and real-world use cases in automotive steering and mirror positioning systems.
Technical Context
The X3G-OH048,005 integrates two parallel Wheatstone bridges on a single bare die, configured at a fixed 45° relative angle to enable orthogonal sinusoidal outputs (sin(2α), cos(2α)) from rotating in-plane magnetic fields. Its operation relies on magneto-resistive response of permalloy thin film, not Hall effect or fluxgate principles.
It requires no external excitation beyond a 5–9 V DC supply, delivers differential bridge outputs referenced to common ground, and maintains amplitude synchronism (k = 98.9–101.1%) and <0.18%FS hysteresis across its full temperature range. Angular inaccuracy remains ≤0.1° due to third/fifth harmonic suppression in the output waveform.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 5–9 V DC - Enables direct compatibility with standard automotive and industrial 5 V/3.3 V supply rails via simple regulation. |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (ON1) | Output voltage bridge 1 (negative) | Differential negative output of cos(2α) bridge - must be routed with matched trace length to OP1 for common-mode rejection. |

| 3 (GND) | Common ground | Reference node for both bridges and supply return - requires low-impedance connection to system ground plane to limit offset drift. |
| 4 (OP2) | Output voltage bridge 2 (positive) | Differential positive output of sin(2α) bridge - used with ON2 to reconstruct full sinusoidal waveform for arctangent calculation. |
| 5 (OP1) | Output voltage bridge 1 (positive) | Differential positive output of cos(2α) bridge - forms quadrature pair with OP2 to enable absolute angle determination. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic angle sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AS5048A-BQFT | Integrated SPI interface, on-chip ADC and angle computation; requires external magnet with axial field orientation. | Designed for PCB-mount assembly with digital output; lacks native differential analog outputs for noise-immune long-cable runs. | Select when system-level processing headroom exists and digital interface simplifies ECU integration. |
| KMZ44 (NXP legacy) | Same internal die design (KMZ44 visible on die), but packaged as leaded SOIC-8; higher parasitic capacitance limits bandwidth to 200 kHz. | Targeted at legacy board designs requiring through-hole or gull-wing footprint; unsuitable for high-speed dynamic sensing above 200 kHz. | Select only for drop-in replacement in existing KMZ44-based designs where bandwidth requirements are ≤200 kHz. |
Compared with AS5048A-BQFT, X3G-OH048,005 offers superior analog noise immunity and 5× higher bandwidth but requires external signal conditioning; compared with KMZ44, it delivers identical core sensing performance in bare-die form for custom hybrid packaging and thermal optimization.

FAQ
What is the primary sensing principle used in the X3G-OH048,005?
The X3G-OH048,005 uses the magneto-resistive effect of thin-film permalloy, not Hall effect or inductive coupling. It contains two Wheatstone bridges oriented at 45° to generate orthogonal sin(2α) and cos(2α) outputs from in-plane rotating magnetic fields - a principle confirmed in Section 1.1 and Figure 5 of the official NXP datasheet.
Does the X3G-OH048,005 require an external magnet, and what field strength is needed?
Yes, the X3G-OH048,005 requires an external rotating magnet parallel to the die surface (x-y plane). A minimum external magnetic field strength of 25 kA/m is required to achieve specified angular accuracy, as defined in Table 5 (Limiting Values) and Section 1.1 of the NXP datasheet.
What is the function of pins ON1, ON2, OP1, and OP2 on the X3G-OH048,005?
Pins OP1 and ON1 form the differential output pair for the cos(2α) bridge; OP2 and ON2 form the differential output pair for the sin(2α) bridge. This configuration is explicitly defined in Table 3 (Pinning) and Figure 2 (Circuit Diagram) of the NXP datasheet, enabling quadrature signal acquisition for absolute angle computation.
Can the X3G-OH048,005 operate reliably at 150 °C ambient temperature?
Yes, the X3G-OH048,005 is fully characterized and guaranteed to operate from −40 °C to +150 °C ambient, with all key parameters (including angular inaccuracy ≤0.1°, offset tempco ≤±2 (μV/V)/K, and bridge resistance tempco = 0.27%/K) specified across this full range per Table 6 (Characteristics).
Is the X3G-OH048,005 pin-compatible with the X3G-OH047 or X3T-OH048 variants?
No - X3G-OH047 is a double-die variant with 12 pads, while X3G-OH048,005 is a single-die device with 6 pads. X3T-OH048 shares identical die functionality and pinout but differs only in tape-and-reel packaging; thus X3G-OH048,005 and X3T-OH048 are functionally and electrically identical, differing solely in packing format.
