UDA1335H

The UDA1335H is designed as a stereo CMOS codec incorporating bitstream converters designed for implementation in USB-compliant audio peripherals and multimedia audio applications. It is an adaptive asynchronous sink USB audio device with a continuous sampling frequency range from 5 to 55kHz. It contains a USB interface, an embedded microcontroller, an analog-to-digital interface (ADIF) and an asynchronous digital-to-analog converter (ADAC).

UDA1335H has many features. (1)USB-compliant audio/HID device. (2)Supports 12Mbits/s 'full speed' serial data transmission. (3)Fully automatic 'plug-and-play' operation. (4)Supports multiple audio data formats (8, 16 and 24bits). (5)5.0 and 3.3V power supply. (6)Low power consumption. (7)Efficient power management. (8)On-chip master clock oscillators, only an external crystal is required. (9)High linearity. (10)Wide dynamic range. And so on.

Some absolute maximum ratings of UDA1335H have been concluded into several points as follow. (1)Its DC input/output voltage range would be min -0.5V and max Vdde. (2)Its output current would be max 4mA. (3)Its junction temperature range would be from 0°C to 125°C. (4)Its storage temperature range would be from -55°C to 150°C. (5)Its operating ambient temperature would be min 0°C and typ 25°C and max 70°C. (6)Its electrostatic handling would be min -3000V and max +3000V through a 1.5kohms series resistor and would be min -300V and max +300V through a 2.5uH series conductor. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of UDA1335H are concluded as follow. (1)Its digital supply voltage periphery would be min 4.75V and typ 5.0V and max 5.25V. (2)Its digital supply voltage core would be min 3.0V and typ 3.3V and max 3.6V. (3)Its operational amplifier supply voltage would be min 3.0V and typ 3.3V and max 3.6V. And so on.
