Product details
Overview
LPY503ALTR from STMicroelectronics is a dual-axis analog MEMS gyroscope measuring pitch and yaw angular rates with ±30°/s full-scale range, 140 Hz bandwidth, 33.3 mV/(°/s) amplified sensitivity, and operation from 2.7 V to 3.6 V across –40 °C to +85 °C - used in digital still camera image stabilization systems.
For engineers reviewing the LPY503ALTR datasheet, LPY503ALTR pinout, LPY503ALTR application, or LPY503ALTR equivalent, this page delivers verified mechanical interface details, dual-output analog signal chain behavior, self-test and power-down control logic, and real-world integration constraints for motion-sensing subsystems.
Technical Context
The LPY503ALTR integrates a single micromachined driving mass operating on the Coriolis principle, with two independent analog signal paths - one per axis - each offering both non-amplified (±120°/s FS) and 4× amplified (±30°/s FS) outputs. Its embedded PLL synchronizes actuation and sensing phases.
Each axis path includes an integrated low-pass filter (–3 dB at 140 Hz), selectable external high-pass reset via HP pin, and buffered 4xOUTX/4xOUTZ outputs with 1.23 V zero-rate level referenced to internal Vref. Self-test applies electrostatic force to verify mechanical integrity without external rotation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Full-scale range | ±30°/s (4× amplified output); enables precise low-rate motion detection for UI navigation and optical stabilization |
| Sensitivity | 33.3 mV/(°/s) (4× output); yields ~1 V output swing over full scale, easing ADC resolution requirements |
| Bandwidth | 140 Hz (–3 dB); supports real-time response for handheld device motion compensation and robotics feedback loops |
| Zero-rate level | 1.23 V (ratiometrically stable); provides fixed DC reference for differential measurement and offset calibration |
| Supply current | 6.8 mA (active), 1–5 µA (power-down); allows battery-powered operation with rapid wake-up via PD pin control |
| Operating temperature | –40 °C to +85 °C; validated for industrial and consumer equipment deployed in uncontrolled thermal environments |
| Shock survivability | 10,000 g / 0.1 ms; ensures robustness during drop events in portable electronics assembly and field use |
Pinout & Package
LGA-16 package (5 mm × 5 mm × 1.5 mm), land grid array with exposed pad; requires JEDEC J-STD-020C-compliant reflow profile and controlled solder paste volume to ensure reliable interconnect to PCB pads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 GND | Ground reference | Primary 0 V return for analog and digital sections; must be low-impedance connection to minimize noise coupling |
| 4 OUTX / 10 OUTZ | Non-amplified analog outputs | Direct sensor outputs (8.3 mV/(°/s)); require external buffering or ADC input conditioning for precision acquisition |
| 6 4xOUTX / 8 4xOUTZ | Amplified analog outputs | Buffered 4× gain outputs (33.3 mV/(°/s)); drive standard 10 kΩ loads with <100 Ω output impedance |
| 11 ST | Self-test enable | Logic-high activates electrostatic test force; output shift confirms mechanical functionality without physical rotation |
| 12 PD | Power-down control | Logic-high reduces supply current to ≤5 µA; enables ultra-low-power sleep modes between motion sampling intervals |
| 13 HP | High-pass filter reset | Logic-high resets external HP filter capacitor; prevents saturation during startup or large transient inputs |
| 7 Vref | Internal reference voltage | Stable 1.23 V source; used to bias 4xINX/4xINZ pins when amplifiers are enabled but external filtering is omitted |
Key Features

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 |
|---|---|---|---|
| LPY510ALTR | ±120°/s full-scale range (non-amplified only); higher bandwidth (190 Hz); same LGA-16 package | Better suited for high-speed motion capture where wide dynamic range outweighs need for amplified low-rate sensitivity | Select when system requires >140 Hz response and can accommodate lower sensitivity (8.3 mV/(°/s)) without external gain stages |
| ADXRS620 | Single-axis, wider FS (±300°/s), SPI digital output, higher power (6 mA active), different SOIC-16 package | Requires microcontroller with SPI interface and software processing; lacks integrated self-test and power-down logic | Choose for systems needing digital interface, higher shock tolerance (2000 g), or single-axis focus with factory-calibrated temperature compensation |
Compared with LPY503ALTR, LPY510ALTR trades amplified output for extended range and bandwidth in identical packaging, while ADXRS620 replaces analog simplicity with digital configurability and higher ruggedness at the cost of added firmware complexity and board space.

FAQ
What is the function of the HP pin on the LPY503ALTR?
The HP (High Pass Filter Reset) pin is a digital control input that, when driven high, discharges the external high-pass filter capacitor to prevent output saturation during power-up or large angular transients. It does not affect internal signal conditioning and must be pulsed high briefly after power-on or before motion capture sequences to ensure baseline stability.
How do I configure the LPY503ALTR for 4× amplified output mode?
To enable 4× amplified output, connect 4xINX (pin 5) and 4xINZ (pin 9) to Vref (pin 7), and route signals from 4xOUTX (pin 6) and 4xOUTZ (pin 8). Do not connect OUTX/OUTZ (pins 4/10) if using amplified outputs exclusively. External low-pass filtering remains optional due to the embedded 140 Hz filter.
Does the LPY503ALTR require external passive components for basic operation?
Yes - FILTVDD (pin 2) and VCONT (pin 3) require external RC network (1 MΩ + 4.7 µF and 33 kΩ + 2.2 µF typical) to configure the internal PLL loop filter. Additionally, 100 nF + 10 µF decoupling capacitors near Vdd (pin 16) and GND (pin 1) are mandatory for stable analog performance and noise immunity.
Can the LPY503ALTR be used without the self-test feature?
Yes - the self-test function is disabled by default when ST (pin 11) is held at GND. Leaving ST unconnected or tied to GND maintains normal operation; only assert ST = Vdd when performing diagnostic verification. No calibration or configuration changes are needed to disable self-test, and it imposes no overhead in idle state.
