LA4636

Ordering number: ENN6985 Monolithic Linear IC LA4636 For General Audio Use 11 W 2-Channel BTL AF Power Amplifier Overview The LA4636 is a BTL power IC that is pin-compatible with the LA4635A and LA4635B single-end power ICs. It represents a new concept in devices of this type by allowing design editing based on common circuit board pin compatibility for products of different power ranks. The LA4636 also incorporates several protection circuits.
