0.5 Ω R, ±15 V, +12 V, ±5 V, +5 V/–12 V, Quad SPST Switch

The ADG2412 contains four independent single-pole/single-throw (SPST) switches. The ADG2412 switches turn on with logic 1 on the digital control inputs. Each switch conducts equally well in both directions when on, and each switch has an input signal range that extends from VSS to VDD − 2 V. When switches are open, signal levels up to the supplies are blocked.

The digital inputs are compatible with 5 V, 3.3 V, and 1.8 V logic inputs without the requirement for a separate digital logic supply pin.

The on-resistance profile is exceptionally flat over the full-analog input range, which ensures good linearity and low distortion when switching audio signals.

PRODUCT HIGHLIGHTS

* Low RON of 0.5 Ω.

* High continuous current carrying capability, see Table 5 to Table 8.

* Dual-supply operation. For applications where the analog signal is bipolar, the ADG2412 can be operated from dual supplies up to ±16.5 V.

* Single-supply operation. For applications where the analog signal is unipolar, the ADG2412 can be operated from a single rail power supply up to 16.5 V.

* 1.8 V logic-compatible digital inputs: VINH = 1.3 V, VINL = 0.8 V.

* No VL logic power supply required.
