It operates from a dual supply of ± 2.7 V to ± 5.5 V, or from a single supply of 2.7 V to 5.5 V. The AG64 switches one of four inputs to a common output,, as determined by the 3-bit binary address lines, A, A1, and EN. A Logic on the EN pin disables the device. The AG64 offers ultralow charge injection of ±1.5 pc over the entire signal range and leakage currents of 1 pa typical at 25 C. It offers on resistance of 85 Ω typ, which is matched to within 2 Ω between channels. The AG64 also has low power dissipation yet gives high switching speeds. The AG64 is available in a 14-lead TSSOP package. PROUCT HIGHLIGHTS 1. Ultralow Charge Injection (Q INJ : ± 1.5 pc Typ over the Full Signal Range) 2.
