Intersil has added the ISL43240 to its rapidly growing MightyMUX high-performance analog switch line. This high-performance IC contains four single-pole double-throw (SPDT) analog switches that provide an R(ON) of less than 20 Ω, at ±5 V and 25°C, and a best-in-class R(ON) flatness of less than 4 Ω guaranteed across input voltage and industrial temperature. Targeted applications include high-precision equipment used for medical, communications, and testing.
The ISL43240 has the flexibility to operate from a +2 to +12 V single supply or from a ±2 to ±6 V dual supply. A very low off-leakage current of less than 100 pA lengthens hold times in sample-and-hold-circuits and fast switching speeds - t(on) = 46 ns, t(off) = 25 ns with dual 5 V supply - reduce propagation delays in timing sensitive applications. These switches offer minimal charge injection of less than 5 pC to maximise signal integrity. All ICs are fully specified at ±5 V, 12, 5 and 3,3 V to save designers characterisation time and increase their confidence in the device's performance.
The near-chip-scale, 20-pad 4 x 4 mm QFN package greatly conserves board space and a 20-lead SSOP package option is also available.
