TMP006EVM Hardware Setup
shows the complete schematic of the TMP006 Test Board. The ferrite bead and input capacitor,
FB
1
and C
1
respectively, filter the power coming into the TMP006 test board from the SM-USB-DIG. The
I
2
C pull-up resistors, R
3
and R
4
, and the DRDY pull-up, R
5
, are required for the open-drain outputs to
operate correctly. The Q
1
and R
6
components drive the LED (D
1
) so current is not provided from the
TMP006 that would cause the device to self-heat. Power, I
2
C, and SPI signals are provided to the
calibration header, H2, for use with the TMP006 calibration tools.
