ƒ Description
The KT0830EG is a high-quality Monolithic Digital FM
Receiver designed to playback high-fidelity FM broadcasting
signals under various conditions.
The KT0830EG offers a true single-chip FM radio solution.
There are no external filters or frequency-tuning devices
thanks to a proprietary digital low-IF architecture, a fully-
integrated LNA, automatic gain control (AGC), high-
performance ADCs, high-quality analog and digital filters, and
an on-chip low-noise self-tuning VCO. The on-chip high-
fidelity Class-AB driver further eliminates the need for any
external audio amplifiers and can drive stereo headphones
The on-chip LDO regulator allows the chip to operate with
power supply ranging from 2.0V to 3.6V consuming merely
19mA in full operation mode and less than 10uA when standby
– greatly extending the battery life.
The small footprint, high integration level and great flexibility
make KT0830EG for any standalone FM radio applications.
