你好：我是提问：6引脚的贴片芯片 封装是SO的 上面写着TZX 哪位大侠知道是上面芯片不？ 你对着图测量一下是不是这个芯片的，具体的型号及参数看下图。希望可以帮到你
开关电源上用的一个6脚贴片芯片封装上面写着Bdf，谁能告诉我芯片名字？ 上图啊如同破案，上面有任何符号，标志都不能放过.
求一个V/F芯片 6引脚贴片封装 基础频率由单片机提供 可以实现2路电压信号的差分转换 谢谢！ AD654挺好用的~PRODUCT DESCRIPTIONThe AD654 is a monolithic V/F converter consisting of an inputamplifier，a precision oscillator system，and a high current outputstage.A single RC network is all that is required to set up anyfull scale(FS)frequency up to 500 kHz and any FS input voltageup to±30 V.Linearity error is only 0.03%for a 250 kHz FS，and operation is guaranteed over an 80 dB dynamic range.Theoverall temperature coefficient(excluding the effects of externalcomponents)is typically±50 ppm/°C.The AD654 operates froma single supply of 5 V to 36 V and consumes only 2.0 mA quies-cent current.The low drift(4 μV/°C typ)input amplifier allows operationdirectly from small signals such as thermocouples or strain gaugeswhile offering a high(250 M？)input resistance.Unlike mostV/F converters，the AD654 provides a square-wave output，andcan drive up to 12 TTL loads，optocouplers，long cables，orsimilar loads。
