volume control

Datasheet - production data

Applications

A22H165M - Flip-chip

 Cellular /smart phones, portable media players

 Wearable

 Fitness and healthcare

It is based on the core technology of a low power

dissipation amplifier combined with a high

efficiency buck converter for supplying this

amplifier.

When powered by a battery, the buck converter

generates the appropriate voltage to the amplifier

depending on the amplitude of the audio signal to

supply the headsets. It achieves a total 2.1 mA

current consumption at 100 µW output power (10

dB crest factor).

Features

 Power supply range: 2.3 V to 4.8 V

 0.6 mA/channel quiescent current

THD+N is 0.02% maximum at 1 kHz and PSRR is

100 dB at 217 Hz, which ensures a high audio

quality of the device in a wide range of

environments.

 2.1 mA current consumption with

100 µW/channel (10 dB crest factor)

 0.006% typical THD+N at 1 kHz

 100 dB typical PSRR at 217 Hz

 100 dB of SNR A-weighted at G = 0 dB

 Zero pop and click

The traditionally bulky output coupling capacitors

can be removed.

A dedicated common-mode sense pin removes

parasitic ground noise.

 I²C interface for volume control

 Digital volume control range from -60 dB to

The A22H165M is designed to be used with an

output serial resistor. It ensures unconditional

stability over a wide range of capacitive loads.

The A22H165M is packaged in a tiny 16-bump

flip-chip package with a pitch of 400 µm.

+4 dB

 Independent right and left channel shutdown

control

 Integrated high-efficiency buck converter

 Low software standby current: 5 µA max

 Output coupling capacitors removed

 Thermal shutdown and short-circuit protection

 Flip-chip package: 1.65 mm x 1.65 mm,

400 µm pitch, 16 bumps
