BA10358xx, BA10324Axx, BA2904xxx, BA2904Sxxx, BA2904Wxx BA2902xx, BA2902Sxx
General Description
General purpose BA10358 / BA10324A and high reliability BA2904 / BA2902 integrate two or four independent Op-Amps on a single chip and have some features of high-gain, low power consumption, and wide operating voltage range of 3V to 36V (single power supply ). BA2904W have low input offset voltage(2mV max.).
Features
Operable with a single power supply Wide operating supply voltage range Input and output are operable GND sense Low supply current High open loop voltage gain Wide temperature range
Application
Current sense application Buffer application amplifier Active filter Consumer electronics
