What is SPS in ADC?
The ADC incorporates a fourth-order, inherently stable, delta-sigma (ΔΣ) modulator. The modulator digital output is filtered and decimated by the internal FIR digital filter to yield the ADC conversion result. The FIR digital filter provides data rates up to 1000 samples per second (SPS).
What is samples per second?
1. sps: Samples per second. In data conversion, an analog signal is converted to a stream of numbers, each representing the analog signal's amplitude at a moment in time. Each number is called a "sample." The number sample per second is called the sampling rate, measured in samples per second.
What is data rate in ADC?
For a "normal" ADC (for example a SAR) the data rate is simply (samples/sec) * (bits/sample). For a sigma-delta the data rate is the raw 1-bit sample rate (which is typically f_clk), divided by the decimation (which is 2^(number of octaves), which is the same thing as 2^(number of bits)).
What does sample rate Hz mean?
Sample rate is the number of samples of audio carried per second, measured in Hz or kHz (one kHz being 1,000 Hz). For example, 44100 samples per second can be expressed as either 44,100 Hz, or 44.1 kHz. Bandwidth is the difference between the highest and lowest frequencies carried in an audio stream.
