KT0830EG

产品概述
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 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.
