LV4985VH - 1.2W x 2ch BTL Power Amplifier

Description

2 13 OUT1-1 OUT2-1 2.49 Power amplifier 1st output pin.

3 4 12 VCC PIN1 PIN2 5.0 2.49 Power supply pin.

Power amplifier input pin.

Features

  • 2-cannels BTL power amplifier built-in : Standard output power = 1.2W (VCC = 5V, RL = 8Ω, THD = 10%) Output coupling capacitor is unnecessary because of differential output type.
  • Volume function built-in (variable range: 69dB standard), DC voltage control system.
  • Mute function built-in (shared with VOL-min).
  • Standby function built-in (three-value control ⇒ Shared with the second amplifier stop control pin) : Standard standby current = 0.01μA (VCC = 5V).
