Ordering number : ENN7253
CMOS IC
LC723481W,723482W,723483W
Low-Voltage ETR-Controller
Overview
The LC723481W, 723482W, and 723483W are lowvoltage 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.
