    • Reference Design for Ultralow Power, General-Purpose, Multichannel Data Acquisition System with Energy Harvesting Circuit and Alert Function

    Overview

    The circuit CN0372 is an ultralow power, multichannel data acquisition system that can be powered by a photovoltaic (PV) cell or thermoelectric generator (TEG). The circuit uses the industry’s lowest power, multichannel, 12-bit successive approximation analog-to-digital converter (SAR ADC), the AD7091R-5, along with an efficient energy harvesting circuit based on the ADP5090 boost regulator. The ADC has a typical power consumption of 100 μW on a single 3 V supply when sampling at 22 kSPS. Typical signal-to-noise ratio (SNR) is 68 dB for a 1 kHz input signal.

    EVAL-CN0372-PMDZEVAL-CN0372-PMDZ circuit board uses the SDP-PMD-IB1ZSDP-PMD-IB1Z interposer board, and the EVAL-SDP-CB1ZEVAL-SDP-CB1Z system demonstration platform (SDP) board. The PMOD interposer board and the SDP controller board have 120-pin mating connectors. The interposer board and the EVAL-CN0372-PMDZEVAL-CN0372-PMDZ board have 12-pin PMOD interface Type 2A and 8-pin I2C interface matching connectors, allowing quick setup and evaluation of the circuit performance.
