Active production — 8:1 CMOS multiplexer with wide supply range
The DG408DY+ is an active-production 8:1 CMOS analog multiplexer/demultiplexer from Analog Devices, in a 16-SOIC surface-mount package.
100 Ohm on-resistance with 1.5 Ohm channel matching
On-state resistance is 100 Ohm maximum, with channel-to-channel matching held to 1.5 Ohm — tight enough that gain error across the eight inputs stays consistent in precision measurement paths. Switching times are symmetrical at 150 ns for both turn-on and turn-off, with charge injection of only 2 pC. Crosstalk between channels measures -92 dB at 100 kHz, which preserves signal integrity in multiplexed data-acquisition front-ends.
Industrial temperature grade and leakage profile
Off-channel leakage is 500 pA maximum, and the channel capacitance (C_off) is 26 pF — a combination that limits settling-time penalties when scanning high-impedance sensor arrays.
