• Manufacturer Part Number: max97220a
• Description: Differential Input Directdrive Line Drivers/headphone Amplifiers
• Manufacturer: Maxim Integrated Products, Inc.

Note 2: 100% production tested at T
Note 3: Dynamic specifications are taken over 2.5V to 5.5V supply range. Inputs AC-coupled to PGND.
Note 4: The maximum differential input signal does not cause any excess distortion due to violation of the common-mode input
Note 5: Test performed with a resistive load connected to PGND. Mode transitions are controlled by SHDN. KCP level is calcu-
