2 / 10 page ![]() I2C Programmable-Gain Amplifier for Audio Applications 2 _____________________________________________________________________ ABSOLUTE MAXIMUM RATINGS RECOMMENDED OPERATING CONDITIONS (TA = -20°C to +70°C.) Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Voltage on VCC, SDA, and SCL Relative to GND.................................................-0.5V to +6.0V Voltage on A0, A1, and A2 Relative to GND ......................................-0.5V to (VCC + 0.5V; not to exceed 6.0V) Voltage on IN+, IN-, OUT-, and OUT+ Relative to AGND .................................-0.5V to (AVCC + 0.5V; not to exceed 6.0V) Voltage on AVCC Relative to VCC..........................-0.3V to +0.3V Voltage on AGND Relative to GND .......................-0.3V to +0.3V Output Current ..................................................................150mA Operating Temperature Range ...........................-20°C to +70°C Storage Temperature .....................See J-STD-020 Specification PARAMETER SYMBOL CONDITIONS MIN TYP MAX UNITS Digital Supply Voltage VCC (Note 1) +4.5 +5.5 V Analog Supply Voltage AVCC VCC V Analog Ground AGND (See Figure 5) GND V Input Logic 1 (SCL, SDA, A0, A1, A2) VIH 2.0 VCC + 0.3 V Input Logic 0 (SCL, SDA, A0, A1, A2) VIL -0.3 +0.8 V ELECTRICAL CHARACTERISTICS (VCC = +4.5V to +5.5V, TA = -20°C to +70°C, unless otherwise noted.)
