Low-Voltage ETR-Controller
Overview
The LC723481W, 723482W, and 723483W are low-
voltage electronic tuning radio microcontrollers that
include a PLL that operates up to 250 MHz and a 1/4 duty
1/2 bias LCD driver on chip. These ICs include an on-chip
DC-DC converter, making it is easy to create the supply
voltages required for tuning and allowing cost reductions
in end products.
These ICs are optimal for use in low-voltage portable
audio equipment that includes a radio receiver.
