ADDRESS 0X4D: TEMP_COUNTER_CONTROL
Bit [7] Measurement mode select bit, set to ‘1’ for recommended
PTAT mode. ‘0’ (default) is IPTAT mode and is less accurate and
not recommended.
Bit [6] Temperature counter enable bit. Set to ‘1’ to enable.
Bit [5] Temperature counter power down bit. Set to ‘1’ to
power-down temperature counter.
Bit [4] Temperature counter reset bit. Set to ‘1’ to reset count.
Bit [3:1] Three bit frequency divider field. Sets temperature
counter update rate. Update rate is proportional to ADC sample
clock rate and divide ratio. A ‘101’ updates the temp counter
every ~66s (for 250MSPS). Faster updates rates result in lower
precision.
Bit [0] Select sampler bit. Set to ‘0’.
This set of registers provides digital access to an PTAT or
IPTAT-based temperature sensor, allowing the system to
estimate the temperature of the die, allowing easy access to
information that can be used to decide when to recalibrate the
A/D as needed.
The nominal transfer function of the temperature monitor should
be estimated for each device by reading the temperature sensor
at two temperatures and extrapolating a line through these two
points.
A typical temperature measurement can occur as follows:
1. Write ‘0xCA’ to address 0x4D - enable temp counter,
divide = ‘101’
2. Wait ≥ 132s (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. Contact the factory for more information if needed.
