FT690 - 1.25W Mono Audio Power Amplifier

General Description

The ft690 is a mono Class-AB audio p ower amplifier designed fo r demandin g applic ations in mobile phones and other portable media devices.

It is capable of delivering 1.

25W of con tinuous outp ut power to an 8Ω BTL load with less than 1% distortion (THD+N) from a 5VDC power supply.

Key Features

  • a low -power shutdown mo de. In the shutdown mode where a logic low is applied onto the SD pin, the amplifier is completely turned off and no supply current will flow through the device. The ft690 also feature s advanced pop & click circuitry which eliminat es noise which woul d otherwise occur durin g turn-o n and turn -off transitions. The ft690 is unity-gain stable and can be configured by external gain-setting resistors.

It is capable of delivering 1. 25W of con tinuous outp ut power to an 8Ω BTL load with less than 1% distortion (THD+N) from a 5VDC power supply. The ft690 is specifically designed t o pro vide hi gh quality o utput powe r w ith a minimal numbe r of external components. The ft690 do es not require output coupling capacitors or bootstr ap capacitors, and is therefore ideal for use in mobile phon es and other low vol tage applications where minimal power consumption is a primary requirement. The ft690 features a low -power shutdown mo de.
