LM4935 Overview
Key Specifications
Package: SMD/SMT
Mount Type: Surface Mount
Pins: 36
Max Voltage (typical range): 5.5 V
Key Features
- a bi-directional I2S serial interface for full range audio and an I2C or SPI compatible interface for control
- The stereo DAC path features an SNR of 88 dB with an 18-bit 48 kHz input
- The mono earpiece amplifier delivers at least 115 mWRMS to a 32Ω bridged-tied load with less than 1% distortion (THD+N) when A_VDD = 3.3V
- The LM4935 also contains a general purpose SAR ADC for housekeeping duties such as battery and temperature monitoring
- This can also be used for analog volume control of the output stages and can trigger interrupt events
- Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external components
- It is therefore ideally suited for mobile phone and other low voltage appli
