BA10358

Standard ICs Dual ground sense operational amplifier BA10358 / BA10358F / BA10358FV / BA10358N The BA10358, BA10358F, BA10358FV, and BA10358N are monolithic ICs with two independent built-in operational amplifiers featuring high gain and frequency compensation. These products offer a particularly wide range of operating voltages, from 3 to 32V (when using a single power supply). Current dissipation is low and remains constant regardless of the power supply voltage. Available packages include an 8-pin DIP (BA10358), an 8-pin SOP (BA10358F), an 8-pin SSOP-B (BA10358FV), and an 8-pin SIP (BA10358N). •1)Features Can be driven with a single power supply. 2) Extremely low current dissipation. 3) Level is compatible with any kind of logic circuit. 4) Operating voltage range is 3 to 32V for single power supply, ±1.5 to ±16V for dual power supply. 5) High DC voltage gain. 6) Wide frequency response. 7) Pin assignments is the same as the general-purpose 4558 model. 8) Compatible with model 358 operation amplifiers of other manufacturers. •Absolute maximum ratings Parameter Symbol Limits BA10358 BA10358F BA10358FV BA10358N Unit Power supply voltage VCC 32 (± 16) 32 (± 16) 32 (± 16) 32 (± 16) V Power dissipation Pd 800∗ 550∗ 350∗ 900∗ mW Differential input voltage VID ± VCC ± VCC ± VCC ± VCC V Common-mode input voltage Vl – 0.3 ~ VCC – 0.3 ~ VCC – 0.3 ~ VCC – 0.3 ~ VCC V Operating temperature Topr – 40 ~ +85 – 40 ~ +85 – 40 ~ +85 – 40 ~ +85 °C Storage temperature Tstg – 55 ~ +125 – 55 ~ +125 – 55 ~ +125 – 55 ~ +125 °C ∗ Refer to the Pd characteristic diagram.
