9 Power Supply Recommendations

The TLV6003 is specified for operation from 2.5 V to 16 V (±1.25 V to ±8 V) over a –40°C to +125°C temperature

range.

CAUTION

Supply voltages larger than 17 V can permanently damage the device.

For proper operation, the power supplies must be properly decoupled. For decoupling the supply lines, place 100

nF capacitors as close as possible to the operational amplifier power supply pins. For single-supply operation,

place a capacitor between VCC and GND supply leads. For dual supplies, place one capacitor between VCC and

ground, and one capacitor between GND and ground.

Low-bandwidth nanopower devices do not have good high-frequency (> 1 kHz) AC PSRR rejection against high-

frequency switching supplies and other 1-kHz and greater noise sources. Therefore, use extra supply filtering if

kilohertz or greater noise is expected on the power supply lines.

10 Layout

10.1 Layout Guidelines

•

Bypass the VCC pin to ground with a low ESR capacitor.

•

The best placement is closest to the VCC and ground pins.

•

Take care to minimize the loop area formed by the bypass capacitor connection between VCC and ground.

•

Connect the ground pin to the PCB ground plane at the pin of the device.

•

Place the feedback components as close as possible to the device to minimize strays.
