Product details
Overview
LPR5150AL from STMicroelectronics is a dual-axis MEMS gyroscope measuring angular rate along pitch and roll axes with ±1500°/s full-scale range, 140 Hz bandwidth, and analog voltage outputs (0.67 mV/°/s sensitivity on 4× amplified channels). It operates from 2.7–3.6 V over –40 °C to +85 °C and is used in motion-sensing gaming controllers and industrial robotics for real-time orientation tracking.
For engineers reviewing the LPR5150AL datasheet, LPR5150AL pinout, LPR5150AL application, or LPR5150AL equivalent, this page delivers verified mechanical and electrical specifications, validated dual-axis analog output behavior, embedded self-test functionality, and LGA-16 package integration guidance - all critical for motion-control BOM validation and PCB layout planning.
Technical Context
The LPR5150AL integrates a single micromachined driving mass and Coriolis-based sensing element with a dedicated CMOS interface IC. Its architecture delivers two independent analog output paths per axis: one unamplified (±6000°/s FS, 0.167 mV/°/s) and one 4× amplified (±1500°/s FS, 0.67 mV/°/s), both with embedded low-pass filtering.
It employs an internal PLL for driving/sensing synchronization, requires external RC components on FILTVDD and VCONT pins, and supports configurable high-pass filter reset via the HP pin. Self-test is activated by logic-high on ST pin, inducing a known electrostatic force to verify mechanical integrity and signal chain functionality.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, GND | Ground reference | 0 V supply return for analog and digital sections; must be low-impedance connection to minimize noise coupling |

| 4, OUTY & 10, OUTX | Unamplified analog outputs | Direct charge-amplifier outputs (±6000°/s FS); require external buffering or ADC input conditioning |
| 5, 4xINY & 9, 4xINX | 4× amplifier inputs | Accept unamplified signals; shorted to OUTY/OUTX when using amplified outputs to avoid signal conflict |

| 14–15, Res | Reserved | Must be tied to Vdd; unused internal functions; floating connection may cause instability |
| 16, Vdd | Power supply | 2.7–3.6 V single supply; requires local 100 nF + 10 µF decoupling per ST layout guidelines |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-axis analog gyroscope applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADXRS645 | Single-axis, digital SPI output; higher noise floor (0.015 °/s/√Hz); wider full-scale (±2000 °/s) | Requires external MCU for axis fusion; better suited for high-dynamic-range inertial navigation than consumer motion UI | Select when digital interface, higher FS, or lower phase delay is prioritized over dual-axis integration and analog simplicity |
| MPU-6050 | 6-axis combo (3g accel + 3°/s gyro); integrated DMP; I²C interface; lower gyro FS (±2000 °/s) but no 4× analog gain option | Enables sensor fusion without external processor; lacks standalone analog gyroscope flexibility for custom signal chains | Select when system-level motion processing (e.g., quaternion output) is needed, not raw analog angular rate per axis |
Compared with ADXRS645 and MPU-6050, the LPR5150AL uniquely delivers dual-axis analog outputs with selectable 1×/4× gain, embedded self-test, and LGA-16 footprint - making it optimal for cost-sensitive, low-power motion UI designs requiring direct ADC interfacing and minimal external components.

FAQ
What is the function of the HP pin on the LPR5150AL?
The HP (High Pass Filter Reset) pin is a digital control input that, when driven high, discharges the external high-pass filter capacitor. This prevents output saturation during large angular transients or at power-up, ensuring accurate DC-coupled rate measurement. It must be pulsed high briefly after power-on or before rapid motion events.
How do the 4xOUT and OUT pins differ in signal chain usage?
The 4xOUT pins provide buffered, 4× amplified analog outputs (±1500°/s FS, 0.67 mV/°/s), suitable for direct ADC connection. The OUT pins deliver unamplified signals (±6000°/s FS, 0.167 mV/°/s) requiring external amplification or higher-resolution ADCs. Using both simultaneously is prohibited - 4xIN pins must be shorted to corresponding OUT pins when 4xOUT is active.
Does the LPR5150AL require external components for basic operation?
Yes - external RC components on FILTVDD and VCONT pins are mandatory to configure the internal PLL loop filter. Additionally, 100 nF + 10 µF decoupling capacitors on Vdd are required per ST layout guidelines. Optional external LPF/HPF components may be added depending on application bandwidth requirements.
Can the LPR5150AL be used in automotive applications?
No - the LPR5150AL is specified for industrial and consumer temperature ranges (–40 °C to +85 °C) and is not qualified to AEC-Q100 automotive standards. ST explicitly states in its documentation that non-automotive-grade parts like the LPR5150AL are intended for use in automotive applications only at the user's own risk and without ST warranty coverage.
