Overview
The TS12A12511 is a bidirectional, single-channel, single-pole double-throw (SPDT) analog switch produced by Texas Instruments. This device is designed to handle analog signals with swings of 0 to 12 V or –6 V to 6 V, conducting equally well in both directions when activated. It features a low ON-state resistance of 5 Ω (typical) and is matched to within 1 Ω between channels. The TS12A12511 is available in various packages, including 8-lead MSOP, 8-lead SOT-23, and 8-pin QFN, making it versatile for different application needs. The device exhibits break-before-make switching action, preventing momentary shorting when switching channels, and it has a maximum current consumption of less than 1 μA and a –3 dB bandwidth of more than 93 MHz.
