LA4302T - Audio Frequency Power Amplifier

Features

  • Ultraminiature package (TSSOP20J): Can be surface mounted on a 4-layer circuit board and requires no heat sink.
  • PO = 8.5 W × 1 channel (VCC = 12 V, RL = 8 Ω, THD = 10%: BTL operation).
  • PO = 4 W × 2 channels (VCC = 12 V, RL = 4 Ω, THD = 10%: SE operation).
  • Built-in electronic switch for switching between BTL and SE operation.
  • Full complement of built-in protection circuits, including circuits that protect against shorting to the power supply, shortin.

Ordering number : ENN7462 Monolithic Linear IC LA4302T 8.5 W × 1 BTL or 4 W × 2 (SE) Audio Frequency Power Amplifier for Desktop PCs Overview The LA4302T is a power amplifier IC that is designed for desktop PCs and applications that use a 4-layer (copper foil) circuit board. It is provided in an ultraminiature package (TSSOP20J) that includes heat dissipation pad. This IC supports both single-channel high-power (BTL) operation and single ended (SE) stereo operation. These operating modes are controlled with an electronic switch. This product also supports the use of a common circuit board in multiple products. Features • Ultraminiature package (TSSOP20J): Can be surface mounted on a 4-layer circuit board and requires no heat sink. • PO = 8.
