bl1555
低导通电阻，双通道，单刀双掷
产品简介
the bl1555 is a dual wide-bandwidth, fast single-pole double-throw (spdt) cmos switch featuring an on-resistance of 0.3 ohm at vdd=5v and wide power supply range from 1.65v to 5.5v. it can be used as an analog switch or as a low-delay bus switch.break-before-make function for both parts eliminates signal disruption during switching from preventing both switches being enabled simultaneously.
优势特点
- wide power supply range:1.65v to 5.5v
- low on-resistance:
- ron(nc) = 0.3ω(vcc=5v)
- ron(no) = 0.3ω(vcc=5v)
- low on-resistance flatness:
- rflat(nc) = 0.08ω(vcc=5v)
- rflat(no) = 0.08ω(vcc=5v)
- -3db bandwidth: 33mhz
- rail-to-rail signal range
- high off-isolation: -66db (f=100 khz)
- crosstalk rejection: -74db
- low total harmonic distortion: 0.035%
