Product details
Overview
LIS3L02AS4 from STMicroelectronics is a low-power, analog-output 3-axis linear accelerometer with user-selectable ±2g/±6g full-scale range, 0.5 mg resolution over 100 Hz bandwidth, and ratiometric output voltage referenced to Vdd. It integrates a MEMS sensing element and CMOS interface in a single SO24 package, enabling precise DC-coupled acceleration measurement for motion-sensing applications including free-fall detection and inertial navigation.
For engineers reviewing the LIS3L02AS4 datasheet, LIS3L02AS4 pinout, LIS3L02AS4 application, or LIS3L02AS4 equivalent, key selection criteria include its analog triple-channel output architecture, self-test and power-down logic control pins, supply-voltage-ratiometric offset/sensitivity, and factory-trimmed calibration at 3.3 V - all critical for embedded motion-sensing system design and signal-chain integration.
Technical Context
The LIS3L02AS4 employs a surface-micromachined silicon proof mass suspended by anchors, with capacitive half-bridge transduction and charge-integration readout. Its fully differential signal chain includes Correlated Double Sampling (CDS) to suppress 1/f noise and offset drift, followed by demultiplexing into three independent S&H stages operating at 66 kHz sampling frequency.
All analog parameters - zero-g level (Voff), sensitivity (So), and self-test output voltage change (Vt) - are ratiometric to Vdd, varying linearly with supply voltage (2.4–3.6 V). The internal 110 kΩ output impedance forms a programmable RC low-pass filter with external load capacitance (≥320 pF), enabling configurable bandwidth down to 1 Hz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.4 V to 3.6 V - enables direct interface with 3.3 V microcontroller I/O domains without level-shifting. |
| Full-Scale Range | ±2 g or ±6 g (FS pin logic-controlled) - selectable trade-off between resolution (0.5 mg @ 2g) and dynamic range. |
| Output Type | Analog voltage (Voutx/Vouty/Voutz) - ratiometric to Vdd, simplifying ADC reference alignment in single-supply systems. |
| Bandwidth | DC to 1.5 kHz (resonance), configurable via external Cload - supports anti-aliasing filtering and noise reduction per axis. |
| Self-Test Function | Digital ST pin activation induces known electrostatic force - verifies mechanical integrity and signal path continuity without external stimulus. |
| Power Consumption | 0.85–1.5 mA active; 2–5 µA in power-down mode - suitable for battery-powered portable devices requiring periodic wake-up sensing. |
| Operating Temperature | −40 °C to +85 °C - qualified for industrial and automotive cabin environments without derating. |
Pinout & Package
Package: SO24 (Small Outline, 24-pin), lead-free and ECOPACK® compliant, 15.6 mm × 7.6 mm × 2.65 mm body height, 0.6 g weight.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 6, GND | Ground reference | Common 0 V return for analog and digital sections - must be low-impedance and decoupled near device. |
| 7, Vdd | Power supply | Primary 2.4–3.6 V supply powering both MEMS sensor and CMOS interface - requires 100 nF + 10 µF local decoupling. |
| 8, Vouty | Analog Y-axis output | Single-ended voltage proportional to Y-axis acceleration - routed to high-Z ADC input or op-amp buffer. |
| 9, ST | Self-test control | Logic 1 activates electrostatic test force; Logic 0 enables normal operation - open-drain compatible with 3.3 V GPIO. |
| 10, Voutx | Analog X-axis output | Single-ended voltage proportional to X-axis acceleration - shares same ratiometric scaling and output impedance as Vouty/Voutz. |
| 11, PD | Power-down control | Logic 1 places device in ultra-low-current state (≤5 µA); Logic 0 enables full operation - supports duty-cycled sensing. |
| 12, Voutz | Analog Z-axis output | Single-ended voltage proportional to Z-axis acceleration - calibrated to match X/Y axes within ±2% cross-axis sensitivity error. |
| 13, FS | Full-scale selection | Logic 0 selects ±2 g range (0.65 V/g sensitivity); Logic 1 selects ±6 g range (0.22 V/g) - sets gain and self-test amplitude. |
Key Features
| Feature | Design Value |
|---|---|
| Factory-trimmed calibration | Zero-g offset and sensitivity stored in non-volatile memory - eliminates need for end-user calibration during production. |
| Ratiometric output | Voff = Vdd/2 ±10%, So = Vdd/5 (2g) or Vdd/15 (6g) - ensures consistent ADC code mapping across supply voltage variations. |
| Programmable bandwidth | 1 Hz to 1.5 kHz via external Cload (320 pF–1.5 nF) - enables optimization of noise vs. response time per application. |
| High shock survivability | 10,000 g for 0.1 ms (unpowered), 3,000 g for 0.5 ms (powered) - withstands drop testing and mechanical handling stress. |
| Embedded self-test | Controlled via ST pin; produces defined ΔVout (±50 mV typical @ 3.3 V, 2g range) - validates sensor functionality in-system. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 3-axis analog accelerometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADXL320ARZ | Single-axis, ±5 g range, higher noise (150 µg/√Hz), no self-test or power-down pin | Lacks multi-axis correlation and embedded diagnostics - unsuitable for free-fall or inertial navigation requiring 3D vector resolution | Select only for cost-sensitive single-axis tilt monitoring where self-test and low-power modes are unnecessary |
| LIS331DLH | Digital (I²C/SPI) output, ±2/±4/±8 g, integrated FIFO, 10-bit ADC, lower current (300 µA) | Requires host MCU firmware for data parsing and interrupt handling - increases software overhead vs. analog simplicity | Prefer when system already uses digital sensors and needs synchronized multi-device timing or burst-mode data capture |
Compared with ADXL320ARZ and LIS331DLH, the LIS3L02AS4 uniquely delivers factory-calibrated analog 3-axis outputs with programmable full-scale, self-test, and power-down - enabling plug-and-play integration into analog-signal-chain designs without firmware dependency or external ADC complexity.

FAQ
What is the minimum external capacitor required on each analog output?
The LIS3L02AS4 requires a minimum load capacitance of 320 pF on Voutx, Vouty, and Voutz to ensure stable operation and meet specified noise and bandwidth performance. This value is mandated by internal 110 kΩ output impedance and prevents oscillation or signal distortion when driving ADC inputs or op-amp buffers.
How does supply voltage variation affect zero-g output and sensitivity?
Both zero-g level (Voff) and sensitivity (So) are ratiometric to Vdd: Voff = Vdd/2 ±10%, So = Vdd/5 (±2g) or Vdd/15 (±6g). At 2.4 V, Voff shifts to ~1.2 V; at 3.6 V, it rises to ~1.8 V. This linear scaling preserves ADC code-to-g conversion accuracy when using the same Vdd as ADC reference.
Can the LIS3L02AS4 measure static (DC) acceleration such as gravity?
Yes - the LIS3L02AS4 is a true DC-coupled accelerometer with no high-pass filtering in its analog signal path. It directly measures constant gravitational acceleration (e.g., +1g on Z-axis when upright), enabling tilt sensing, orientation detection, and free-fall initiation based on sustained acceleration changes.
What is the functional difference between ST and PD pins?
The ST pin controls electrostatic self-test activation (Logic 1 applies test force; Logic 0 disables it), while the PD pin enables ultra-low-power shutdown (Logic 1 reduces current to ≤5 µA; Logic 0 restores full operation). Both are active-high, CMOS-compatible digital inputs with 0.8 V/2.2 V logic thresholds at 3.3 V supply.
