TA8255AHQ - Max Power 22W BTL x 4ch Audio Power IC

Description

1.

Voltage gain adjustment This IC has no NF (negative feedback) terminals.

Therefore, the voltage gain can’t adjusted, but it makes the device a space and total costs saver.

Features

  • Weight: 9.8g (typ. ).
  • High power : POUT (max) = 22 W (typ. ) (VCC = 13.7 V, f = 1 kHz, RL = 4 Ω) : POUT (1) = 17 W (typ. ) (VCC = 14.4 V, f = 1 kHz, THD = 10%, RL = 4 Ω) : POUT (2) = 14 W (typ. ) (VCC = 13.2 V, f = 1 kHz, THD = 10%, RL = 4 Ω).
  • Low distortion ratio : THD = 0.02% (typ. ) (VCC = 13.2 V, f = 1 kHz, POUT = 3 W, RL = 4 Ω).
  • Low noise : VNO = 0.10 mVrms (typ. ) (VCC = 13.2 V, Rg = 0 Ω, GV = 34 dB, BW = 20~20 kHz).
  • Built.
  • in stand.
  • by switch.
