National Semiconductor's LM4540VH is an 18-bit Audio Codec '97 interface, offering a comprehensive solution for digital audio processing. This Sigma Delta device features two ADCs and two DACs, each with a typical dynamic range of 90 dB for ADCs and 89 dB for DACs. The serial data interface facilitates efficient communication, and the component is housed in a 48-TQFP (7x7) package for surface mounting. Operating across an ambient temperature range of -40°C to 85°C, the LM4540VH supports analog supply voltages from 4.2V to 5.5V and digital supply voltages from 3V to 5.5V. This audio codec is commonly utilized in consumer electronics, including home audio systems and multimedia devices.
