9 Power Supply Recommendations

The LMV3xxA-Q1 family is specified for operation from 2.5 V to 5.5 V (±1.25 V to ±2.75 V); many specifications

apply from –40°C to 125°C. The Typical Characteristics section presents parameters that may exhibit significant

variance with regard to operating voltage or temperature.

CAUTION

Supply voltages larger than 6 V may permanently damage the device; see the Absolute Maximum

Ratings table.

Place 0.1-µF bypass capacitors close to the power-supply pins to reduce coupling errors from noisy or high-

impedance power supplies. For more detailed information on bypass capacitor placement, see the Layout

Guidelines section.

9.1 Input and ESD Protection

The LMV3xxA-Q1 family incorporates internal ESD protection circuits on all pins. For input and output pins,

this protection primarily consists of current-steering diodes connected between the input and power-supply pins.

These ESD protection diodes provide in-circuit, input overdrive protection, as long as the current is limited to

10 mA. Figure 9-1 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 and the value must be kept to a minimum in

noise-sensitive applications.
