ADT7473/ADT7473-1
Rev. C | Page 14 of 72
Table 9 shows the input ranges of the analog inputs and output
codes of the 10-bit ADC.
When the ADC is running, it samples and converts a voltage
input in 711 μs and averages 16 conversions to reduce noise; a
measurement takes nominally 11.38 ms.
ADDITIONAL ADC FUNCTIONS FOR VOLTAGE
MEASUREMENTS
A number of other functions are available on the ADT7473/
ADT7473-1 to offer the system designer increased flexibility.
Turn-Off Averaging
For each voltage measurement read from a value register,
16 readings have actually been made internally and the results
averaged before being placed into the value register. When
faster conversions are needed, setting Bit 4 of Configuration
Register 2 (0x73) turns averaging off. This effectively gives a
reading 16 times faster (711 μs), but the reading may be noisier.
Bypass Voltage Input Attenuator
Setting Bit 5 of Configuration Register 2 (0x73) removes the
attenuation circuitry from the VCCP input. This allows the user
to directly connect external sensors or to rescale the analog
voltage measurement inputs for other applications. The input
range of the ADC without the attenuators is 0 V to 2.25 V.
Single-Channel ADC Conversion
Setting Bit 6 of Configuration Register 2 (0x73) places the
ADT7473/ADT7473-1 into single-channel ADC conversion
mode. In this mode, the ADT7473/ADT7473-1 can be made to
read a single voltage channel only. If the internal ADT7473/
ADT7473-1 clock is used, the selected input is read every
711 μs. The appropriate ADC channel is selected by writing to
Bits [7:5] of the TACH1 minimum high byte register (0x55).
