LM4540VHX

The LM4540VHX is one member of the LM4540 family which is designed as the audio codec that can be used in PC audio systems requiring only 2 stereo inputs (CD, Line) and 3 mono inputs (Mic, Phone, PC Beep). The key specifications of this device are: (1)A/D dynamic range: 90dB (typ);(2)analog mixer dynamic range: 95dB (typ);(3)D/A dynamic range: 89dB (typ). Also it features AC-Link, a synchronous, fixed rate serial bus for connection to the digital AC '97 controller. Features of the LM4540VHX are:(1)audio codec '97 compliant; (2)stereo 18-Bit SD A/D's and D/A's with 128X oversampling; (3)national's 3D sound circuitry; (4)power management support; (5)digital Interface 3V and 5V compliant.

The absolute maximum ratings of the LM4540VHX can be summarized as:(1)supply voltage: 6.0V;(2)storage temperature: -65°C to +150°C;(3)input voltage: -0.3V to VDD+0.3V;(4)ESD susceptibility:2500 V;(5)junction temperature:150°C.
