TMP05 OUTPUT

The TMP05 has a push-pull CMOS output (Figure 28) and

provides rail-to-rail output drive for logic interfaces. The rise

and fall times of the TMP05 output are closely matched so that

errors caused by capacitive loading are minimized. If load

capacitance is large (for example, when driving a long cable),

an external buffer could improve accuracy.

An internal resistor is connected in series with the pull-up

MOSFET when the TMP05 is operating in one shot mode.

TMP06 OUTPUT

The TMP06 has an open-drain output. Because the output

source current is set by the pull-up resistor, output capacitance

should be minimized in TMP06 applications. Otherwise,

unequal rise and fall times skew the pulse width and introduce

measurement errors.
