Give Trackpads Your Signature Feel with High-Fidelity Haptics

Precision haptics, integrated hardware and software, and expert support for distinctive, brand-defining trackpad experiences built for high-volume production.

Use Cases

Precisely Tuned Trackpads, Reliably Fulfilled Production

Trackpads are expected to feel precise, premium, and responsive to the user. Experiences must hold up across different actuator choices, production variation, and high-volume manufacturing; getting both right at once is where Cirrus comes in.

Primary Click Feedback
Deliver a crisp, reliable response for everyday selection, navigation, and control.
Configurable Click Profiles
Tune tactile character for different PC designs, user preferences, and product tiers.
Gesture and Interaction Confirmation
Use distinct tactile responses to acknowledge supported gestures, actions, or interface states.
Large and Thin Trackpad Designs
Support vividly different trackpad experiences within the mechanical and manufacturing constraints of modern device form factors.

Product Spotlight

CS40L50: Closed-Loop Control for Better Trackpads

Integrated DSP, waveform memory, and closed-loop algorithms help deliver sharper, more consistent haptic feedback.

Platform Benefits

Design Control and Flexibility Across All Your Designs

Control Click Feel
Closed-loop haptics sense actual trackpad motion and adjust the drive signal in real time, rather than firing a fixed, pre-set pulse.
Improve Consistency
Characterize and calibrate each actuator's real behavior, so tuning is based on measured performance.
Tune in Software
Set and adjust click response through register writes and wavetable edits, no schematic or hardware change required.
Scale Across Designs
Scale your haptics approach across devices, built to adapt to different mechanics, actuators, and system-level constraints.

Everything You Need to Evaluate, Design, and Ship Effortlessly

Cirrus Logic supports OEMs, ODMs, and platform teams with evaluation resources, software, documentation, application expertise, and regional engineering support for trackpad integration and tuning.

Frequently Asked Questions

Closed-loop haptics uses feedback from the system to control the tactile response rather than relying only on an open-loop drive signal.

This gives designers greater control over response and consistency, helping the intended click feel carry across supported trackpad designs and production conditions.
