ADES1830/ADES1831 16-Channel Battery Monitors

Analog Devices ADES1830/ADES1831 16-Channel Battery Monitors measure up to 16 series-connected battery cells and offer a lifetime total measurement error (TME) of <2mV for the ADES1830 and <5mV for the ADES1831 over the full temperature range. The measurement input range of -2V to +5.5V makes these multicell devices suitable for most battery chemistries and allows the measurement of voltages across bus bars. Two individual analog-to-digital converters (ADCs) measure all cells simultaneously and redundantly. The continuously operating ADCs, with a 4.096MHz sampling rate, enable reduced external analog filtering and aliasing-free measurement results. Subsequent programmable infinite impulse response (IIR) filters can provide higher noise reduction.
