Description
AI
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 VSSto 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 HIGHLIGHTSLow RONof 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 VLlogic power supply required.APPLICATIONSAutomatic test equipmentData acquisitionInstrumentationAvionicsAudio and video switchingCommunication systemsRelay replacement
