Analog output protection and detection solution Overvoltage protection up to ±60 V on S and SFB pins Power off protection up to ±60 V on S and SFB pins Integrated 0.6 kΩ secondary feedback channel Known output under all conditions User enabled, power-on condition pulls source to 0 V Known state without digital inputs present Latch-up immune Optimized resistance for measurement channel and feedback channel Low on resistance of 6 Ω typical on signal channel Ultraflat, on resistance on signal channel 3 mm × 2 mm LFCS VSS to VDD −2 V signal range Fully specified at ±15 V, ±20 V, +12 V, and +36 V The ADG5401F main channel switch is a SPST, low on-resistance switch that features overvoltage protection, power off protection, and overvoltage detection on the source pins (S and SFB). The ADG5401F also features a protected secondary feedback channel for use with digital-to-analog converter (DAC) or amplifier outputs. When no power supplies are present, the switch remains in the off condition, and the switch inputs are high impedance. When powered, if the analog input signal levels on the S pin exceed VDD or VSS by a threshold voltage (VT) the switch turns off, the open-drain FF pin pulls to a logic low and a path between the D and DFB pins is switched on to prevent an open-loop condition on the amplifier output. Input signal levels up to +60 V or −60 V relative to ground are blocked, in both the powered and unpowered condition.
