Product details
Overview
LY330ALHTR from STMicroelectronics is a single-axis analog yaw-rate gyroscope based on MEMS technology, delivering ±300 dps full-scale range, 140 Hz bandwidth, and 3.752 mV/dps sensitivity in an LGA-10 (3×5×1 mm) package. It operates from 2.7 V to 3.6 V across –40 °C to +85 °C and integrates self-test, sleep mode, and embedded low-pass filtering for motion-sensing applications in remote controllers and GPS navigation systems.
For engineers reviewing the LY330ALHTR datasheet, LY330ALHTR pinout, LY330ALHTR application, or LY330ALHTR equivalent, key selection criteria include analog output linearity (±1% FS), zero-rate level stability (1.5 V ±0.2*Vdd), temperature drift of sensitivity (0.01 %/°C), and configurable power modes via SLEEP/PD and ST pins.
Technical Context
The LY330ALHTR uses a Coriolis-effect-driven single-mass resonant structure with continuous oscillation, coupled to a CMOS interface IC that provides factory-trimmed analog voltage output (OUTZ). Its internal PLL synchronizes driving and sensing paths, and the VCONT pin supports external RC filtering to set low-pass response.
Power management is implemented through three discrete modes-normal, sleep, and power-down-controlled by logic states on SLEEP/PD and ST pins. Self-test applies electrostatic actuation to verify mechanical integrity and signal chain functionality without external rotation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Full Scale Range | ±300 dps - defines maximum measurable angular rate before output saturation |
| Sensitivity | 3.752 mV/dps - fixed gain enabling direct voltage-to-rate conversion without scaling |
| Bandwidth | 140 Hz - supports real-time motion tracking up to human-hand gesture frequencies |
| Zero-Rate Level | 1.5 V at Vdd = 3 V - DC output offset under no rotation; stable within ±0.02 dps/°C drift |
| Supply Voltage | 2.7 V to 3.6 V - compatible with standard 3.3 V system rails and LDO-regulated supplies |
| Operating Temp | –40 °C to +85 °C - qualified for industrial and automotive cabin environments |
| Rate Noise Density | 0.014 dps/√Hz - determines minimum detectable rotation in low-amplitude motion capture |
Pinout & Package
LGA-10 (3×5×1 mm) land grid array package with exposed thermal pad; RoHS-compliant, ECOPACK® certified, JEDEC J-STD-020 solder-reflow qualified.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| GND (Pin 4) | Ground reference | Primary analog ground return path for sensor and output circuitry |
| OUTZ (Pin 6) | Analog output | Single-ended voltage output proportional to yaw-rate; ratiometric to Vdd |
| Vref (Pin 7) | Reference voltage | Internal trimmed reference used for biasing and calibration; not user-accessible |
| SLEEP/PD (Pin 8) | Mode control input | Logic-controlled entry into sleep or power-down; sets current draw to 2.2 mA or 5 µA |
| ST (Pin 2) | Self-test activation | High-level assertion triggers electrostatic mass deflection for functional verification |
| VCONT (Pin 3) | PLL filter node | External RC network sets low-pass cutoff and stabilizes phase-locked drive frequency |
| Res (Pins 5 & 10) | No-connect / Vdd tie | Unused terminals; may be tied to Vdd to reduce floating node susceptibility |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar single-axis analog gyroscope applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADXRS649 | Wider ±2000 dps range; higher 2.5 mA supply current; requires external op-amp for output buffering | Better suited for high-dynamic-range inertial measurement, less ideal for low-power portable devices | Select when extended range and robustness to mechanical shock (>10,000 g) outweigh power and board space constraints |
| MPU-6050 | Digital I²C output; integrated 3-axis accelerometer + 3-axis gyroscope; 3.3 V only; no analog OUTZ pin | Enables sensor fusion without external ADC but adds firmware complexity and fixed digital interface timing | Select when multi-axis data and embedded DMP offload justify added software integration effort |
Compared with ADXRS649 and MPU-6050, the LY330ALHTR offers the lowest system-level BOM count for dedicated yaw-rate sensing-requiring no external ADC, op-amp, or firmware-based sensor fusion-while maintaining best-in-class analog stability and sub-5 µA power-down current.

FAQ
What is the function of the VCONT pin on the LY330ALHTR?
The VCONT pin connects to an external RC network that sets the cutoff frequency and phase margin of the internal PLL-based low-pass filter. A typical configuration uses a 10 kΩ resistor and 470 nF capacitor to achieve the specified 140 Hz bandwidth while ensuring loop stability. This pin must not be left floating.
How does the self-test feature operate electrically?
When the ST pin is driven high, an electrostatic force deflects the MEMS mass, generating a known DC-level shift at OUTZ-typically 400 mV at Vdd = 3 V. This shift is additive to the real-world angular rate output, allowing verification of both mechanical response and analog signal chain integrity without physical rotation.
Can the LY330ALHTR be used in a 5 V system?
No-the absolute maximum supply voltage is 6 V, but the device is specified and factory calibrated only for 2.7 V to 3.6 V operation. Supplying 5 V violates electrical characteristics, risks permanent damage per Table 5, and invalidates all guaranteed parameters including sensitivity, zero-rate level, and noise performance.
Is the LY330ALHTR pin-compatible with other ST gyroscopes like the LY330AL?
Yes-the LY330ALHTR shares identical pinout, package dimensions, and electrical interface with the LY330AL (tray version); only packaging differs (tape-and-reel vs. tray). All functional pins-including dual Vdd, SLEEP/PD, ST, and VCONT-map identically, enabling drop-in replacement in production PCBs.
