2W Mono BTL Audio Power Amplifier

General Description

Key Specifications

Improved PSRR at 217Hz & 1KHz

66dB

The ft690 is an audio power amplifier primarily designed

for demanding applications in mobile phones and other

portable communication device applications. It is capable

of delivering 1.25 watts of continuous average power to

an 8Ω BTL load and 2 watts of continuous average

power (DFN only) to a 4Ω BTL load with less than 1%

distortion (THD+N+N) from a 5VDC power supply.

Power Output at 5.0V, 1% THD+N, 4Ω (QFN only)

2W (typ)

Power Output at 5.0V, 1% THD+N, 8Ω 1.25W (typ)

Power Output at 3.0V, 1% THD+N, 4Ω 600mW (typ)

Power Output at 3.0V, 1% THD+N, 8Ω 425mW (typ)

Shutdown Current 0.1μA (typ)

The ft690 was designed specifically to provide high

quality output power with a minimal amount of external

components. The ft690 does not require output coupling

capacitors or bootstrap capacitors, and therefore is ideally

suited for mobile phone and other low voltage

applications where minimal power consumption is a

primary requirement.

Features

Available in space-saving packages: DFN, MSOP,

WCSP

Ultra low current shutdown mode

Improved pop & click circuitry eliminates noise during

turn-on and turn-off transitions

The ft690 features a low-power consumption shutdown

mode. To facilitate this, Shutdown may be enabled by

either logic high or low depending on mode selection.

Driving the shutdown mode pin either high or low

enables the shutdown pin to be driven in a likewise

manner to enable shutdown.

2.2 - 5.5V operation

No output coupling capacitors, snubber networks or

bootstrap capacitors required

Unity-gain stable

External gain configuration capability

User selectable shutdown High or Low logic Level

The ft690 contains advanced pop & click circuitry which

eliminates noise which would otherwise occur during

turn-on and turn-off transitions.

Applications

The ft690 is unity-gain stable and can be configured by

external gain-setting resistors.

Mobile Phones

PDAs

Portable electronic device
