Product Overview

The MAX97220BETE+T is a differential input DirectDrive line drivers/headphone amplifier in 16 pin TQFN package. This device is capable of driving line level loads with 3VRMS into 1Kohm with a 5V supply and 2VRMS into 600 ohm loads from a 3.3V supply. A headphone load is capable of being driven with 125mW into 32ohm with a 5V supply. The IC is offered with an externally set gain through external resistors. The external gain setting nodes can also be used to configure filters for set-top box applications. The IC has exceptional THD+N over the full audio bandwidth. It is used for set top box applications, feature a 130ms tON. An on-chip charge pump inverts the power supply input, creating a negative rail. The output stage of the amplifier is powered between the positive input supply and the output of the charge pump. The bipolar supplies bias the output about ground, eliminating the need for large, distortion-introducing output coupling capacitors.
  • Supply voltage range is 2.5V to 5.5V
  • Operating temperature range from -40°C to 85°C
  • Fully differential inputs
  • IC powers on and off without clicks or pops
  • DirectDrive outputs eliminate DC blocking capacitors
  • Flat THD+N better than 90dB in the audio band
  • 18bit SNR performance is 112dB
