10 Power Supply Recommendations
The TLV379 family is specified for operation from 1.8 V to 5.5 V (±0.9 V to ±2.75 V); many specifications apply from –40°C to +125°C. The Typical Characteristics section presents parameters that can exhibit significant variance with regard to operating voltage or temperature.
CAUTION
Supply voltages larger than 7 V can permanently damage the device (see the Absolute Maximum Ratings table).
Place 0.1-μF bypass capacitors close to the power-supply pins to reduce errors coupling in from noisy or high-impedance power supplies. For more detailed information on bypass capacitor placement; see the Layout Guidelines section.
10.1 Input and ESD Protection
The TLV379 family incorporates internal electrostatic discharge (ESD) protection circuits on all pins. In the case of input and output pins, this protection primarily consists of current-steering diodes connected between the input and power-supply pins. These ESD protection diodes also provide in-circuit, input overdrive protection, as long as the current is limited to 10 mA as stated in the Absolute Maximum Ratings table. Figure 20 shows how a series input resistor can be added to the driven input to limit the input current. The added resistor contributes thermal noise at the amplifier input that must be kept to a minimum in noise-sensitive applications.
