WM8524G-Stereo-DAC

Description :

The WM8524G is a stereo DAC with integral charge pump and hardware control interface. This provides 2Vrms line driver outputs using a single 3.3V power supply rail. The device features ground-referenced outputs and the use of a DC servo to eliminate the need for line driving coupling capacitors and effectively eliminate power on pops and clicks.
The device is controlled and configured via a hardware control interface.
The device supports all common audio sampling rates between 8kHz and 192kHz using all common MCLK fs rates. The audio interface operates in slave mode. The WM8524 has a 3.3V tolerant digital interface, allowing logic up to 3.3V to be connected.

Features

1. High performance stereo DAC with ground referenced line driver
2. All common sample rates from 8kHz to 192kHz supported
3. Hardware control mode
4. Data formats: LJ, RJ, I2S
5. Maximum 1mV DC offset on Line Outputs
6. Pop/Click suppressed Power Up/Down Sequencer

Description :

The T6322 is a continuous mode inductive step-down converter, designed for driving single or multiple series connected LEDs efficiently from a voltage source higher than the LED voltage. The device operates from an input supply between 7V and 30V and provides an externally adjustable output current of up to 1.5A. Depending upon supply voltage and external components, this can provide up to 42 watts of output power. The T6322A includes the output switch and a high side output current sensing circuit, which uses an external resistor to set the nominal average output current.
