dynamic range needed for many applications, but only at the expense of low update rates. This circuit presents an alternative approach that uses theAD798516-bit, 2.5 MSPS PulSAR®successive-approximation ADC, combined with an autorangingAD8253iCMOS®programmable gain instrumentation amplifier (PGA)...
Commonly expressed in decibels (dBV = 20 × log10 of the voltage ratio), it indicates the range of signal amplitudes that the ADC can resolve; an ADC with a dynamic range of 60 dB can resolve signal amplitudes with a range of 1000:1. For an N-bit ADC, the dynamic range (DR) can...
For an ADC, the dynamic range is related to the number of bits that are used to digitize the analog signal. Consider an ideal N-bit ADC. The minimum value that can be detected is one least significant bit (LSB). The maximum value is 2N−12N−1 times the LSB value. Hence, in ...
, the signal-to-noise ratio, signal-to-noise-and-distortion ratio, effective-number- of-bits, and total-harmonic-distortion of the 16-bit ADC chip 7606 have errors from the typical values of 0.39 dB, 0.23 dB, 0.16 bit, and 7.24 dB, respectively, which are within the manual range. ...
The PCM1809 also supports a power-down and reset function by means of halting the system clock. The PCM1809 consists of the following blocks and features: • Stereo-channel, multibit, low-power delta-sigma (ΔΣ) ADC • Differential audio inputs with a 2-VRMS full-scale signal • ...
Multilayer boards with separate ground and power planes produce the highest level of signal integrity. Consider the use of a split ground plane arranged to match the physical location of analog and digital grounds on the ADC's package. The impedance of the two ground planes must be kept as lo...

The oversampling technique is most often used with the Δ-Σ ADC, but it is also useful with the SAR ADC. In this article we will dive in a bit deeper to see how this works.
