The AD7768/AD7768-4 achieve 108 dB dynamic range at a maximum input bandwidth of 110.8 kHz, combined with typical
MT-002: What the Nyquist Criterion Means to Your Sampled ...
www.analog.comMost ADCs today have a built-in sample-and-hold function, thereby allowing them to process ac signals. This type of ADC is referred to as a sampling ADC. However many early ADCs, such as Analog Devices' industry-standard AD574, were not of the sampling type, but simply encoders as shown in Figure 2. If the input signal to a SAR ADC (assuming no ...

www.st.comADC sampling rate is 3.6 Msps in 16-bit mode. When 3 ADCs are sampling simultaneously, the system throughput can reach up to 10.5 Msps. Higher data rates per channel can be obtained when a single channel is converted by two ADCs in dual-interleaved mode. The data rate can reach up to 7 Msps in 16-bit mode and 10 Msps in 14-bit mode.

Delta-sigma ADCs in a nutshell
www.rpi.eduDelta-sigma ADCs in a nutshell Part one of a three-part series exploring the basic topology and functions of delta-sigma ADCs. By Bonnie Baker -- EDN, 12/14/2007 Delta-sigma converters are ideal for converting signals over a wide range of frequencies from dc to several megahertz with very-high-resolution results.

ume.gatech.eduHow Does it Work Cont. At t<0, S 1 is set to ground, S 2 is closed, and counter=0. At t=0 a conversion begins and S 2 is open, and S 1 is set so the input to the integrator is V in. S 1 is held for T INT which is a constant predetermined time interval. When S 1 is set the counter begins to count clock pulses, the counter resets to zero after T
