The MAX signal chain consists of the following: a flexible input multiplexer that can be set to manage three fully differential signals or five pseudo-differential signals, two chopper amplifiers, a programmable PGA (with gain from 1 to ), a coarse DAC to remove system offset, and a second-order sigma-delta :// Sigma Delta A/D Conversion for Signal Conditioning (The Springer International Series in Engineering and Computer Science) by Kathleen Philips; Arthur H.M.

How delta-sigma ADCs work, Part 1 Analog techniques have dominated signal processing for D and near the input-signal spur, D is the conversion frequency of the digital/decimation filter.

Selecting a value for f D will be discussed in Part 2 of this article series. Modulators: The Sigma-Delta Converter. A fairly new commercial converter is the sigma-delta ADC (sometimes referred to as a delta-sigma converter). This device is a low-cost, high-resolution ADC, suitable for low conversion rates.

Sigma-delta ADCs typically have 16 to bit resolution, with a usable input signal frequency range of a few Hz to a few :// As the block diagram shows, a basic sigma-delta A/D converter consists of an oversampling modulator, followed by a digital filter and a decimator.
