description:
|
|
RT9123 is a 3.2W mono Class-D audio amplifier that features high efficiency
|
|
and performance with ultra-low quiescent current. The digital audio interface
|
|
support various formats, including I2S, left-justified, right-justified, and
|
|
TDM formats.
|
|
|
|
RTQ9124 is an ultra-low output noise, digital input, mono-channel Class-D
|
|
power amplifier that supports a 2.1MHz switching frequency. It integrates
|
|
both DC and AC load diagnostics, as well as real-time load monitoring to
|
|
assess speaker condition. The device operates from 4.5V to 18V and delivers
|
|
up to 30W output power.
