AD8450ASTZ
电池管理 Precision Analog Front End and Controller for Battery Test/Formation Systems
GENERAL DESCRIPTION AD8450ASTZ
The AD8450 is a precision analog front end and controller for testing and monitoring battery cells. A precision programmable gain instrumentation amplifier (PGIA) measures the battery charge/discharge current, and a programmable gain difference amplifier (PGDA) measures the battery voltage (see Figure 1). Internal laser trimmed resistor networks set the gains for the PGIA and the PGDA, optimizing the performance of the AD8450 over the rated temperature range. PGIA gains are 26, 66, 133, and 200. PGDA gains are 0.2, 0.27, 0.4, and 0.8.
