The part operates from a single supply of 10V to 30V or dual supplies of ±4.5V to ±20V, making it adaptable to a wide range of industrial and instrumentation signal chains. On-resistance of 85 Ohm max sets the insertion loss for the signal path — in a precision measurement front-end, that resistance combined with the load determines the voltage divider error. The 4 Ohm channel-to-channel matching keeps gain errors consistent across all four switches, which matters for multi-channel data acquisition where each channel must track the same transfer function. Crosstalk of -100 dB at 1 MHz. Switching times of 250 ns turn-on and 170 ns turn-off define the maximum update rate for the multiplexer. For a sample-and-hold front-end, the 250 ns acquisition window sets the upper bound on throughput — roughly 4 Msps if the switch is the only timing bottleneck. Charge injection of 5 pC. Off-leakage current of 500 pA max keeps the error floor low when the switch is open. In a multiplexed ADC input with 10 kOhm source impedance, 500 pA contributes 5 µV of offset — negligible for most industrial analog inputs. The 16-SOIC package (0.154\" body width, 3.90 mm) is a standard footprint shared by many quad analog switches, simplifying board layout and second-sourcing.","metaTitle":"DG442DY+ Quad SPST Analog Switch, 85 Ohm, 16-SOIC","metaDescription":"DG442DY+ quad SPST analog switch from Maxim Integrated. 85 Ohm on-resistance, -100dB crosstalk at 1MHz, 16-SOIC.
