? 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 fullyintegrated LNA, automatic gain control (AGC), highperformance ADCs, high-quality analog and digital filters, and

an on-chip low-noise self-tuning VCO. The on-chip highfidelity Class-AB driver further eliminates the need for any

external audio amplifiers and can drive stereo headphones

directly.

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.
