Table 5 summarizes the duration of each state and the
achievable output data rate as a function of F
O
.
Ease of Use
The
LTC2480
data output has no latency, filter settling
delay or redundant data associated with the conversion
cycle. There is a one-to-one correspondence between the
conversion and the output data. Therefore, multiplexing
multiple analog voltages is easy.
The LTC2480 performs offset and full-scale calibrations
every conversion cycle. This calibration is transparent to
the user and has no effect on the cyclic operation described
above. The advantage of continuous calibration is extreme
stability of offset and full-scale readings with respect to time,
supply voltage change and temperature drift.
Power-Up Sequence
The LTC2480 automatically enters an internal reset state
when the power supply voltage V
CC
drops below approxi-
mately 2V. This feature guarantees the integrity of the
conversion result and of the serial interface mode selection.
When the V
CC
voltage rises above this critical threshold,
the converter creates an internal power-on-reset (POR)
signal with a duration of approximately 4ms. The POR
signal clears all internal registers. Following the POR
signal, the LTC2480 starts a normal conversion cycle and
follows the succession of states described in Figure 1. The
first conversion result following POR is accurate within the
specifications of the device if the power supply voltage is
restored within the operating range (2.7V to 5.5V) before
the end of the POR time interval.
On-Chip Temperature Sensor
The LTC2480 contains an on-chip PTAT (proportional to
absolute temperature) signal that can be used as a tem-
perature sensor. The internal PTAT has a typical value of
420mV at 27
°
C and is proportional to the absolute tempera-
ture value with a temperature coefficient of 420/(27 + 273)
= 1.40mV/
°
C (SLOPE), as shown in Figure 4. The internal
PTAT signal is used in a single-ended mode referenced to
device ground internally. The GAIN is automatically set to
one (independent of the values of GS0, GS1, GS2) in order
to preserve the PTAT property at the ADC output code and
avoid an out of range error. The 1x speed mode with au-
tomatic offset calibration is automatically selected for the
internal PTAT signal measurement as well.
