Product details
Overview
LIS3L06AL from STMicroelectronics is a low-power, 3-axis analog-output MEMS accelerometer with user-selectable ±2g/±6g full-scale range, 0.5 mg resolution over 100 Hz bandwidth, ratiometric output (Vout ∝ Vdd), and embedded self-test functionality - deployed in mobile terminals, free-fall detection systems, and robotics for inertial motion sensing.
For engineers reviewing the LIS3L06AL datasheet, LIS3L06AL pinout, LIS3L06AL application, or LIS3L06AL equivalent, this page delivers verified mechanical/electrical specs, LGA-8 pin mapping, real-world use cases in data protection and VR input, and validated alternative options for design continuity.
Technical Context
The LIS3L06AL integrates a surface-micromachined capacitive sensing element with a fully differential CMOS interface featuring Correlated Double Sampling (CDS) to suppress offset and 1/f noise. Its charge amplifier and three independent sample-and-hold (S&H) circuits operate at 200 kHz and 66 kHz respectively, enabling oversampling for improved signal fidelity.
All analog parameters - zero-g level (Voff), sensitivity (So), and self-test voltage change (Vt) - are ratiometric to Vdd; Vt varies cubically with supply voltage, and full-scale selection (FS pin) switches internal gain between ±2g (Vdd/5) and ±6g (Vdd/15) modes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.4 V to 3.6 V - enables direct integration with 3.3 V logic rails without level-shifting. |
| Full-Scale Range | ±2g or ±6g (FS pin-controlled) - allows dynamic trade-off between resolution (0.5 mg @ 2g) and range. |
| Bandwidth | DC to 1.5 kHz (resonance), configurable down to 1 Hz via external Cload - supports anti-aliasing filter design per application. |
| Output Impedance | 80–140 kΩ - requires high-Z ADC inputs or buffer amplifiers to avoid loading errors. |
| Self-Test Function | Digital ST pin activation induces calibrated DC-level shift (±50 mV typical @ 2g/3.3 V) - verifies mechanical integrity and signal chain end-to-end. |
| Operating Temperature | −40°C to +85°C - qualified for industrial and consumer portable environments without derating. |
| Shock Survivability | 10,000 g / 0.1 ms - withstands board-level handling and drop events without functional loss. |
Pinout & Package
Package: 3 mm × 3 mm × 0.85 mm LGA-8 (Land Grid Array), ECOPACK® lead-free, JEDEC J-STD-020C compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 ST | Self-Test Control Input | Logic high (≥0.7×Vdd) activates electrostatic test force; logic low (≤0.3×Vdd) enables normal operation. |
| 2 Voutz | Analog Output (Z-axis) | Single-ended ratiometric voltage (Vdd/2 ± ΔV) proportional to Z-axis acceleration; Rout ≈ 110 kΩ. |
| 3 GND | Ground Reference | 0 V return path for supply and analog outputs; must be low-impedance and decoupled near device. |
| 4 Reserved | No Connect | Internally unconnected; must remain floating - no external tie or pull-up/down. |
| 5 FS | Full-Scale Selection Input | Logic high selects ±6g mode (sensitivity = Vdd/15); logic low selects ±2g mode (sensitivity = Vdd/5). |
| 6 Vouty | Analog Output (Y-axis) | Single-ended ratiometric voltage for Y-axis; identical electrical behavior to Voutz and Voutx. |
| 7 Voutx | Analog Output (X-axis) | Single-ended ratiometric voltage for X-axis; zero-g level = Vdd/2 ± 6% at 25°C. |
| 8 Vdd | Power Supply Input | 2.4–3.6 V analog/digital supply; requires local 100 nF ceramic + 10 µF bulk decoupling. |
Key Features
| Feature | Design Value |
|---|---|
| Ratiometric Analog Outputs | Vout scales linearly with Vdd, eliminating need for separate reference voltage when using ratiometric ADCs. |
| User-Selectable Full Scale | Hardware-configurable ±2g/±6g range via single digital FS pin - no firmware or register writes required. |
| Embedded Self-Test | Electrostatic actuation validates sensor mass movement and signal chain integrity without external stimulus. |
| Low-Power Operation | 1.5 mA typical supply current enables battery-powered operation in handheld and wearable devices. |
| High Shock Survivability | Rated to 10,000 g for 0.1 ms - survives PCB reflow, drop testing, and mechanical stress in final assembly. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 3-axis analog-output MEMS accelerometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADXL335 | Fixed ±3g range, higher noise density (300 µg/√Hz), no self-test, wider supply (1.8–3.6 V) | Lacks hardware full-scale switching and embedded self-test - requires external validation routines. | Choose for cost-sensitive, non-safety-critical tilt sensing where ±3g range suffices and self-test is optional. |
| LIS331DLH | Digital (I²C/SPI) output, ±2g/±4g/±8g programmable range, 10-bit resolution, integrated FIFO | Requires MCU firmware for configuration and data parsing; no analog ratiometric simplicity. | Choose when digital interface, lower power (300 µA), or multi-range flexibility outweighs analog signal chain simplicity. |
Compared with ADXL335 and LIS331DLH, the LIS3L06AL uniquely combines hardware-selectable full scale, analog ratiometric outputs, and embedded self-test in an LGA-8 package - making it optimal for robust, low-complexity motion sensing where analog integration and field-reliable diagnostics are critical.

FAQ
What is the recommended external capacitor value for 100 Hz anti-aliasing filtering on LIS3L06AL outputs?
For a 100 Hz cutoff frequency, use 15 nF ceramic capacitors on each Voutx/Vouty/Voutz pin. This pairs with the device's nominal 110 kΩ output impedance (ft = 1.45 µF / Cload) and ensures flat response below resonance while suppressing high-frequency noise. Minimum Cload is 1 nF; tolerance of Rout (±20%) means actual ft may vary ±20%.
How does the LIS3L06AL's self-test function validate sensor health in-system?
Asserting ST = Vdd applies an electrostatic force that shifts each analog output by a calibrated DC voltage (e.g., ±50 mV typical on X/Y at ±2g/3.3 V). Measuring this shift confirms both mechanical mobility of the proof mass and correct operation of the charge amplifier, CDS circuitry, and S&H stages - all without external equipment.
Can LIS3L06AL operate reliably at 2.4 V supply, and how does that affect sensitivity?
Yes, LIS3L06AL is fully specified from 2.4 V to 3.6 V. Sensitivity and zero-g level scale ratiometrically: at 2.4 V, ±2g sensitivity is ~0.48 V/g (vs. 0.66 V/g at 3.3 V), and zero-g level centers at ~1.2 V. Factory trimming maintains accuracy across voltage, but self-test output changes with Vdd³ - so test thresholds must be scaled accordingly.
Why is the Reserved pin (Pin 4) required to remain unconnected?
Pin 4 is internally unconnected silicon - no bond wire, no routing, no ESD structure. Connecting it risks introducing noise coupling, unintended parasitic capacitance, or latch-up if tied to Vdd/GND. ST's datasheet explicitly mandates leaving it floating; solder mask coverage or NC marking on PCB layout prevents accidental routing.
