RCV420使用求助

Other Parts Discussed in Thread: RCV420

新接触TI的放大器产品,在网站申请的RCV420JP样片,在洞洞板上根据DataSheet中Fig1的原理图焊接了测试板。有几个问题想要请教一下:

1. DataSheet中提到供电建议采用+15V和-15V,但是手头暂时没有相应的供电电源。采用+12V和-12V电源供电有问题吗?如果电源不稳定,或者正负电压的绝对值不相等,会影响芯片的工作吗?

2. 如何评估RCV420是否正常工作呢?

3. DataSheet中提到的Protecting The Sense Resistor是必须的吗?

十分期待你们的解答。
