Product Overview
The TS3A5018 is a Texas Instruments quad SPDT analog switch for Signal_Chain designs. Its switch configuration provides four single-pole double-throw channels, with an IN pin used as the switch path selector input and an active-low EN pin for enable control. The device is specified for a single-supply operating range of 1.8 V to 3.6 V, with recommended supply voltage from 1.65 V to 3.6 V.
At 3.3 V operation, the analog signal range is 0 V to V+ across -40°C to 85°C. On-state resistance is specified as 7 ohm typical, 10 ohm maximum at 25°C, and 12 ohm maximum across the full range under the stated 3 V, -32 mA test condition. Signal-chain parameters include 300 MHz typical bandwidth, -48 dB typical off isolation, -48 dB typical crosstalk, and -81 dB typical adjacent crosstalk at 10 MHz.
Package options include SOIC-16, SSOP-16, TSSOP-16, TVSOP-16, UQFN-16, and VQFN-16 footprints. Thermal resistance ranges from 51°C/W for VQFN-16 to 184°C/W for UQFN-16. The device is suited to low-voltage analog signal routing and switch path selection within the stated voltage, current, leakage, capacitance, and temperature limits.
