STAC9227 General Description
The STAC9227/9228/9229/9230 are a family of Theater Quality 8-channel audio CODECs that enable systems with 7.1 audio or 5.1 audio playing simultaneously with VoIP or another stereo audio stream. SigmaTel's proprietary technology provides high fidelity with an estimated DAC SNR up to 105dB. Up to four digital microphones are supported enabling high quality voice input for increased usability of voice applications.
STAC9227 Maximum Ratings
Stresses above the ratings listed below can cause permanent damage to the STAC9227/9228/9229/9230. These ratings, which are standard values for IDT commercially rated parts, are stress ratings only. Functional operation of the device at these or any other conditions above those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods can affect product reliability. Electrical parameters are guaranteed only over the recommended operating temperature range.
| Item | Pin | Maximum Rating |
| Analog maximum supply voltage | AVdd | 6 Volts |
| Digital maximum supply voltage | DVdd | 5.5 Volts |
| VREFOUT output current | 5 mA | |
| Voltage on any pin relative to ground | Vss - 0.3 V to Vdd + 0.3 V | |
| Operating temperature | 0 to +70 | |
| Storage temperature | -55 to +125 | |
| Soldering temperature | 260 for 10 seconds * Soldering temperature information for all available packages begins on page 229. |
