Frequently Asked Questions
What is the configuration of the TS12A4515DG4 analog switch?
The TS12A4515DG4 is a single-pole single-throw (SPST) analog switch in a normally-closed (NC) configuration. When no control signal is applied, the switch is closed (conducting). Asserting the control input opens the switch, providing simple active-open switching for signal gating and muting applications in audio and instrumentation circuits.
What supply voltages does the TS12A4515DG4 support?
The TS12A4515DG4 is designed to operate with supply voltages of 3V, 5V, 9V, and 12V, and also functions with a 12V single supply as noted in its specifications. This multi-supply flexibility enables its use across a wide range of systems from low-voltage portable devices to industrial 9V and 12V rail designs without component changes.
What is the analog signal input voltage range of the TS12A4515DG4?
The TS12A4515DG4 supports analog signal input voltages from -4.5V to +5.5V, allowing it to switch AC audio signals and bipolar sensor outputs without clipping. This bipolar signal handling capability makes it particularly useful in audio routing, instrumentation signal paths, and analog multiplexers where the signal may swing below ground.
What package is the TS12A4515DG4 available in?
The TS12A4515DG4 is housed in an 8-pin SOIC (Small Outline IC) package designated JESD-30 R-PDSO-G8. The compact SMT package is well suited for space-constrained audio mixing boards, portable test instruments, and industrial signal conditioning modules where a single analog switch must fit within a small PCB area.
