Audio Special Purpose

digital audio attenuator62 dB attenuationmute3-wire serialSOIC-8Texas Instruments

LM1971MX/NOPB is an 8-pin digitally controlled mono audio attenuator providing 0 dB to -62 dB attenuation in 1 dB steps plus mute.

Best for

  • Single-channel programmable analog volume control
  • Audio level control requiring 1 dB steps
  • Systems requiring a serial mute function

Avoid if

  • Applications needing a linear potentiometer behavior
  • Outputs that must directly drive low-impedance loads
  • Systems without a suitable half-supply reference

Check before use

  • Confirm 4.5 V to 12 V supply compatibility
  • Implement the required 16-bit serial frame
  • Review output-buffer input bias current and impedance
  • Account for power-up mute behavior
