The TPA6140A2YFFEVM allows the engineer to evaluate the TPA6140A2, a stereo Class-G DirectPath™ (capacitor-free) headphone amplifier in a WCSP package. The TPA6140A2 has extremely low power consumption that enables much longer battery life in portable applications.

  • Highly Power-Efficient Class-G Operation
  • DirectPath™ Ground-Referenced Outputs
  • Power Supply Voltage Range: 2.5 V to 5.5 V
  • I2C Volume Control: -59 dB to +4 dB Gain Range
  • Separate SGND Input for Preventing Ground Loop Noise
  • High Power Supply Rejection Ratio
  • Differential Inputs for Maximum Noise Rejection
  • Advanced Pop and Click Suppression Circuitry
  • High-Impedance Output Mode
  • Tiny 1.6 mm x 1.6 mm 16-WCSP (0.4mm pitch)
