ISLA214P50
A typical temperature measurement can occur as follows:
1. Write ’0xCA’ to address 0x4D - enable temp counter, divide
=’101’
2. Wait >= 132µs (at 250Msps) - longer wait time ensures the
sensor completes one valid cycle.
3. Write ‘0x20’ to address 0x4D - power-down, disable temp
counter - recommended between measurements. This
ensures that the output does not change between MSB and
LSB reads.
4. Read address 0x4B (MSBs)
5. Read address 0x4C (LSBs)
6. Record temp code value
7. Write ‘0x20’ to address 0x4D - power-down, disable temp
counter
