Product Overview
ADS1274IPAPR is a multichannel wide-bandwidth delta-sigma ADC designed to sample four analog inputs simultaneously. It avoids the channel-to-channel time skew created by one muxed ADC scanning several dynamic signals.
With rates to roughly 144 kSPS and 70 kHz bandwidth, it fits vibration, acoustic, test and industrial dynamic measurements rather than slow temperature/bridge monitoring. The linear-phase digital filter preserves relative waveform timing across frequency, useful for phase analysis between channels.
High-quality reference and low-jitter clock design are first-order system requirements at this performance level. The 64-pin HTQFP also exposes more power, clock and channel-routing complexity than compact sensor ADCs.

Functional Highlights
Simultaneous sampling preserves inter-channel phase
Four converters capture the same time instant, which matters for vibration vectors, power analysis and multi-sensor correlation.
Linear-phase filtering protects waveform relationships
Constant group delay avoids frequency-dependent phase distortion that can corrupt multi-tone or transfer-function analysis.
Design Considerations
- Use a low-jitter clock source and short controlled clock routing.
- Drive the reference with low noise and enough dynamic current for all four converters.
- Treat analog input anti-alias filtering and channel-to-channel layout symmetry as part of phase/amplitude accuracy.
