10 Power Supply Recommendations

The maximum recommended operating voltage of the TMP64-Q1 is 5.5 V (V Sns), and the maximum current

through the device is 100 µA (ISns).

11 Layout

11.1 Layout Guidelines

The layout of the TMP64-Q1 is similar to that of a passive component. If the device is biased with a current

source, the positive pin 2 is connected to the source, while the negative pin 1 is connected to ground. If the

circuit is biased with a voltage source, and the device is placed on the lower side of the resistor divider, V– is

connected to ground, and V+ is connected to the output (VTEMP). If the device is placed on the upper side of the

divider, V+ is connected to the voltage source and V– is connected to the output voltage (VTEMP). Figure 11-1

shows the device layout.
