10 Power Supply Recommendations

The MCP629x series is specified for operation from 2.4 V to 5.5 V (±1.2 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 6 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

Example section.

10.1 Input and ESD Protection

The MCP629x series 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, as stated in the Absolute Maximum Ratings table. Figure 35 shows how a series input resistor is 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.
