Analog DevicesEVAL-CN0235-SDPZEntwicklungssätze und Werkzeuge

EVAL-CN0235-SDPZ is Fully Isolated Lithium Ion Battery Monitoring and Protection System Evaluation Board. The AD7280A is a complete data acquisition system that includes a high voltage input multiplexer, a low voltage input multiplexer, a 12-bit, 1 μs SAR ADC, and on-chip registers for channel sequencing. The HV MUX is used to measure the series connected Li-Ion battery cells as shown in Figure 1. The LV MUX provides single-ended ADC inputs that can be used with external thermistors to measure the temperature of each battery cell; or, if temperature measurements are not required, the auxiliary ADC inputs can be used to convert any other 0 V to 5 V input signal. A precision 2.5 V reference and an on-chip voltage regulator is also included.
