CALCULATION OF REGISTRATION FEE

EXPLANATORY NOTE

Synaptics Incorporated, a Delaware corporation (the “Registrant”) is filing this Registration Statement to register an additional 2,059,425 shares of its common stock, par value $0.001 per share (“Common Stock”), for issuance under the Registrant’s Amended and Restated 2019 Equity and Incentive Compensation Plan (the “2019 Plan”). The 2019 Plan was amended by the Registrant’s Board of Directors on July 27, 2021 to increase the number of shares of Common Stock authorized for issuance thereunder by 2,000,000 shares, and such amendment was approved by the Registrant’s stockholders on October 26, 2021. In substitution of outstanding awards under the DSP Group, Inc. (“DSP”) Amended and Restated 2012 Equity Incentive Plan immediately prior to the consummation of the Registrant’s acquisition of DSP on December 2, 2021, the Registrant is granting restricted stock unit awards under the 2019 Plan covering 59,425 shares of Common Stock that shall become issuable under the 2019 Plan upon vesting of such awards.

This Registration Statement is being filed for the purpose of increasing the number of securities of the same class as other securities for which a Registration Statement on Form S-8 relating to the same benefit plan is effective pursuant to the amendment to the 2019 Plan described above and the issuance of the substitute restricted stock unit awards. The Registrant previously registered shares of its Common Stock for issuance under the 2019 Plan under a Registration Statement on Form S-8 filed with the Securities and Exchange Commission (“SEC”) on November 1, 2019 (File No. 333-234437) and November 2, 2020 (File No. 333-249793). Pursuant to General Instruction E to Form S-8, this Registration Statement hereby incorporates by reference the contents of the Registration Statements referenced above with respect to the shares of common stock registered under the 2019 Plan, except to the extent supplemented or amended or superseded by the information set forth or incorporated herein.

Re:    Securities Being Registered under Registration Statement on Form S-8

We have acted as counsel to you in connection with your filing of a Registration Statement on Form S-8 (the “Registration Statement”) pursuant to the Securities Act of 1933, as amended (the “Securities Act”), on or about the date hereof relating to an aggregate of 2,059,425 shares (the “Shares”) of Common Stock, $0.001 par value per share (“Common Stock”), of Synaptics Incorporated, a Delaware corporation (the “Company”), that may be issued pursuant to the Company’s Amended and Restated 2019 Equity and Incentive Compensation Plan (the “Plan”).

We have reviewed such documents and made such examination of law as we have deemed appropriate to give the opinions set forth below. We have relied, without independent verification, on certificates of public officials and, as to matters of fact material to the opinion set forth below, on certificates of officers of the Company.

The opinion set forth below is limited to the Delaware General Corporation Law.

For purposes of the opinion set forth below, we have assumed that no event occurs that causes the number of authorized shares of Common Stock available for issuance by the Company to be less than the number of then unissued Shares.

Based on the foregoing, we are of the opinion that the Shares have been duly authorized and, upon issuance and delivery against payment therefor in accordance with the terms of the Plan, will be validly issued, fully paid and nonassessable.

We hereby consent to the inclusion of this opinion as Exhibit 5.1 to the Registration Statement. In giving our consent, we do not admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations thereunder.

Exhibit 23.2

Consent of Independent Registered Public Accounting Firm

We consent to the use of our report dated August 20, 2021, with respect to the consolidated balance sheets of Synaptics Incorporated as of June 26, 2021 and June 27, 2020 and the related consolidated statements of operations, comprehensive income/(loss), stockholders’ equity and cash flows for each of the years in the three-year period ended June 26, 2021 and the related notes (collectively the “consolidated financial statements”), and the effectiveness of internal control over financial reporting, incorporated herein by reference.
