NOISE MEASUREMENTS
The ADS1194/6/8 noise performance can be optimized by adjusting the data rate and PGA setting. As the
averaging is increased by reducing the data rate, the noise drops correspondingly. Increasing the PGA value
reduces the input-referred noise, which is particularly useful when measuring low-level biopotential signals.
Table 1 summarizes the noise performance of the ADS1194/6/8, with a 3V analog power supply. Table 2
summarizes the noise performance of the ADS1194/6/8 with a 5V analog power supply. The data are
representative of typical noise performance at TA = +25°C. The data shown are the result of averaging the
readings from multiple devices and are measured with the inputs shorted together. A minimum of 1000
consecutive readings are used to calculate the peak-to-peak noise for each reading. For the two highest data
rates, the noise is limited by quantization noise of the ADC and does not have a gaussian distribution. The ratio
between rms noise and peak-to-peak noise for these two data rates are approximately 10. For the lower data
rates, the ratio is approximately 6.6.
Table 1 and Table 2 show measurements taken with an internal reference. In many of the settlings, espeically at
the lower data rates, the inherent device noise is less than 1LSB. For these cases, the noise is rounded up to
1LSB. The data are also representative of the ADS1194/6/8 noise performance when using a low-noise external
reference such as the REF5025.
