9.3 Power Supply Recommendations

The TMP113 operates with power supply in the range of 1.4V to 5.5V and slew rate as low as 10mV/ms.

The device can measure temperature accurately in the full supply range. A power-supply bypass capacitor is

required for proper operation. Place this capacitor as close as possible to the supply and ground pins of the

device. A typical value for this supply bypass capacitor is 0.01μF. Applications with noisy or high-impedance

power supplies can require additional decoupling capacitors to reject power-supply noise.

9.4 Layout

9.4.1 Layout Guidelines

The TMP113 is a simple device to layout. Place the power-supply bypass capacitor as close as possible to

the supply and ground pins. The recommended value of this bypass capacitor is 0.01μF. Additional decoupling

capacitance can be added to compensate for noisy or high-impedance power supplies. Pull up the open-drain

output pins (SDA, SCL and ALERT) through 5kΩ or 20kΩ pullup resistors.
