This reference voltage is temperature protected and is meant to be used as a way to compensate for temperature changes.
If this op amp amplifies a reference voltage by this linear gain, then the op amp's output voltage is also a linear function of potentiometer value.
The 0.5% reference voltage satisfies the need of precision voltage to the modern ASICs.
In such a case, the reference voltage is eliminated from the temperature calculation, thus easing the reference requirements.
This configuration stabilizes the reference voltage to the ADC allowing a more stable conversion.
The op amp then compares the temperature reference voltage against the thermistor voltage and the difference is amplified and fed into the MAX8520/21.
Special precision resistors and a highly stable reference voltage source keep the 1523 accuracy virtually insensitive to environmental temperature.
This is possible because the reference voltage to FSOTC DAC and offset TC DAC is the BDR(sensor-excitation) voltage, which is temperature dependent.
The reference voltage can be adjusted by means of a resistor depending on the LEDs used and the expected working range.
Hence if the PWM reference voltage is set to its maximum value of +5V, then the motor should run at 4000 rpm.
If there's an error in the reference voltage, this results in an error in the measured data.
The ADC then generates a code representing the relationship between an input signal and that reference voltage.
This design approach improves the measurement accuracy by feeding the ADC's reference voltage to one of the analog multiplier's inputs.
Figure 1. This graph shows allowable temperature coefficients for 1 LSB variation of reference voltage per degree of difference from room temperature.
A DAC generates the comparator's reference voltage to compensate for DC offsets.
The motor driver can be configured so that when the speed reference voltage is as at its maximum of +5V, the commanded speed is 100,000rpm.
Ultralow-noise LDOs such as the ADM7151 will not benefit from the noise-reduction network because the architecture uses the LDO error amplifier in unity gain, so the reference voltage is equal to the output voltage. .
IC5 is a bandgap reference whose 1.2V output is buffered by op amp IC2d to provide a reference voltage for the dual DACs in IC4.
The duty cycle of the signal reduces the feedback reference voltage proportionally.
This also reduces the signal from the bridge and reduces the reference voltage.
