Product details
Overview
PAM8016AKR from Diodes Incorporated is a filterless haptic driver IC designed for low-latency, high-efficiency actuation of Linear Resonance Actuators (LRA) and Eccentric Rotating Mass (ERM) elements. It operates from 2.8V to 5.5V, delivers up to 3.0W into 4Ω at 5V, achieves 93% efficiency at 8Ω, and features differential/single-ended/PWM input support - enabling tactile feedback in compact portable devices such as smartphones and wearables.
For engineers reviewing the PAM8016AKR datasheet, PAM8016AKR pinout, PAM8016AKR application, or PAM8016AKR equivalent, key selection criteria include its ultra-low EMI (-20dB vs FCC Class-B), 4ms startup time, <1μA shutdown current, and U-FLGA1515-9 package compatibility with space-constrained haptic subsystems.
Technical Context
The PAM8016AKR integrates a PWM modulator, gate drivers for high-side pMOS (325mΩ RDS(on)) and low-side nMOS (200mΩ RDS(on)), UVLO (2.0V trip), thermal shutdown (150°C), and short-circuit protection. Its filterless Class-D architecture eliminates external LC output filters while maintaining THD+N ≤0.17% at 1W/8Ω.
It supports closed-loop gain control (up to 300k/Rin), operates at 400kHz switching frequency, and provides differential input capability with ±20mV output offset voltage. Startup response is optimized for sub-5ms activation - critical for button-click haptic feedback timing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.8V to 5.5V - enables direct integration with single-cell Li-ion or USB-powered systems without LDO pre-regulation. |
| Max Output Power | 3.0W into 4Ω at 5V - sufficient to drive high-force LRAs for crisp, localized tactile alerts in mobile handsets. |
| Efficiency | 93% at 8Ω, 10% THD - minimizes thermal load and extends battery life in always-on wearable haptic interfaces. |
| THD+N | 0.14% at 5V, 0.5W, 4Ω - ensures clean waveform reproduction for precise resonance tuning of LRAs. |
| Startup Time | 4ms - meets sub-10ms latency requirement for real-time touch response in UI navigation and gaming peripherals. |
| Shutdown Current | <1μA - allows persistent connection to system rail without measurable battery drain during sleep modes. |
| EMI Performance | -20dB below FCC Class-B limit at 300MHz - eliminates need for ferrite beads in most consumer-grade PCB layouts. |
Pinout & Package
The PAM8016AKR is housed in a 1.5mm × 1.5mm, 9-pin U-FLGA1515-9 ultra-thin flip-chip glass-epoxy package with 0.5mm pitch and NiPdAu terminations - optimized for minimal PCB footprint and high-density haptic module integration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | IN+ | Differential positive analog input - accepts bias-centered AC signal for full-scale LRA drive without DC blocking issues. |
| A2 | GND | Analog ground reference - separate from power ground in layout to reduce noise coupling into sensitive input path. |
| A3 | OUT- | Negative output terminal - forms differential pair with C3 (OUT+) to deliver balanced drive to LRA coil. |
| B1 | VDD | Main logic and analog supply - powers internal bias, oscillator, and control circuitry; requires 1μF local decoupling. |
| B2 | PVDD | Power-stage supply - feeds H-bridge drivers; must be independently decoupled with 10μF ceramic for low-impedance current sourcing. |
| B3 | GND | Power ground - dedicated return path for H-bridge switching currents; tied to A2 at single point under device. |
| C1 | IN- | Differential negative analog input - enables common-mode noise rejection when paired with A1 for robust ERM/LRA control. |
| C2 | SD | Active-low shutdown control - pulls device into ultra-low-power state (<1μA) when driven to GND by host MCU GPIO. |
| C3 | OUT+ | Positive output terminal - delivers complementary phase to A3 for true differential haptic actuator excitation. |
Key Features
| Feature | Design Value |
|---|---|
| Filterless Class-D architecture | Eliminates external LC output filter - reduces BOM count by ≥2 components and saves ≥2.5mm² PCB area per channel. |
| Dual haptic element support | Configurable drive for both LRA (resonant frequency tuning) and ERM (broadband vibration) - simplifies platform reuse across product tiers. |
| Flexible input interface | Accepts differential analog, single-ended analog, or PWM inputs - allows direct connection to AP DACs, GPIOs, or audio codecs without level-shifting. |
| Integrated protection suite | UVLO, short-circuit, and overtemperature (150°C trip + 40°C hysteresis) - prevents field failures in thermally constrained wearable enclosures. |
| Ultra-low EMI emission | -20dB below FCC Class-B at 300MHz - passes radiated emissions testing without added shielding or layout revisions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar haptic driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Texas Instruments DRV2605L | Integrated waveform RAM and I²C interface; higher system-level integration but requires external boost converter for >3.6V operation. | Better suited for complex, programmable haptic effects; less optimal for simple analog-triggered feedback due to firmware overhead. | Select when advanced haptic library support and closed-loop LRA auto-resonance tracking are required. |
| Analog Devices ADA4870 | High-voltage (40V) op-amp-based driver; no integrated protection or filterless architecture; requires external MOSFETs and feedback network. | Used in high-force industrial actuators; lacks native ERM/LRA optimization and consumes significantly more board area. | Select only for non-standard haptic loads exceeding 5.5V or requiring >10W output - not drop-in compatible. |
Compared with DRV2605L and ADA4870, the PAM8016AKR offers superior integration for cost-sensitive, space-constrained portable designs - delivering full haptic functionality with zero external active components, lowest EMI, and fastest startup - while avoiding firmware dependencies or high-voltage complexity.

FAQ
What input types does the PAM8016AKR support?
The PAM8016AKR accepts differential analog (IN+/IN−), single-ended analog (IN+ referenced to GND), or PWM inputs. For PWM, an external RC low-pass filter with ≤10kHz cutoff is recommended to suppress high-frequency switching artifacts before driving the haptic element.
How does the PAM8016AKR achieve filterless operation?
It uses a proprietary modulation scheme and optimized gate drive timing to minimize high-frequency energy in the output spectrum, allowing direct connection to LRA/ERM loads without LC filtering. This reduces EMI, PCB area, and component count while maintaining THD+N ≤0.17% at 1W.
What protection features are built into the PAM8016AKR?
The device integrates undervoltage lockout (2.0V trip), short-circuit protection (output-to-output or output-to-GND), and overtemperature protection (150°C trip with 40°C hysteresis). All protections are automatic and self-recovering - no external fault-handling circuitry is needed.
Can the PAM8016AKR drive both LRA and ERM actuators simultaneously?
No - it drives one haptic element per device using a single differential output pair (OUT+/OUT−). However, its flexible input architecture and dual-element support mean the same design can be reused across LRA- or ERM-based platforms without hardware change - only input signal configuration differs.
