LA4146 Description

Short technical summary and product information.

The Sanyo Denki LA4146 is a monolithic linear IC designed as an AF Power Amplifier. It is particularly suited for use in mini musical instrument applications.

 

The device features a typical output power of 0.6 W into an 8 Ω load or 0.9 W into a 4 Ω load, both at 10% total harmonic distortion and a supply voltage of 6.0 V. The voltage gain is fixed at a typical 50 dB, with an option to reduce it using an external resistor. The input resistance is typically 30 kΩ.

 

Key features include soft clipping and minimal pop noise during ON/OFF mode transitions. The operating voltage range is from 3.6 V to 8 V, with a recommended supply voltage of 6 V and a recommended load resistance of 8 Ω. The maximum allowable power dissipation is 4 W.

 

The LA4146 is housed in a 3017B-S9IC package. It operates within a temperature range of -40°C to +70°C.
