1.1 Ohm on-resistance and channel isolation for precision analog routing
The ADG1612BRUZ-REEL7 is a quad SPST-NO analog switch from Analog Devices, built for low-distortion signal switching in precision analog chains. Its 1.1 Ohm max on-resistance keeps voltage drop and thermal dissipation minimal when routing audio, sensor, or data-acquisition signals through the four independent channels. Channel-to-channel crosstalk is rated at -110 dB at 1 MHz, meaning a signal on one channel couples into an adjacent channel at less than 3 µV for a 1 V swing — critical for multiplexing low-level transducer outputs without ghosting.
Supply flexibility and switching speed
The 38 MHz -3 dB bandwidth supports video or fast-settling ADC front-ends. Switching times are 156 ns typical turn-on and 87 ns typical turn-off, fast enough for multiplexed data acquisition at sample rates up to several megahertz. Charge injection is 170 pC — moderate for sample-and-hold circuits; a downstream buffer or longer acquisition window absorbs the glitch.
Package, temperature grade, and compliance
Housed in a 16-lead TSSOP package (4.40 mm width), surface-mount, supplied on Tape & Reel. The industrial temperature range spans -40°C to +125°C, so the switch holds its 1.1 Ohm on-resistance and leakage specs across automotive and outdoor equipment thermal profiles. Analog Devices lists the ADG1612BRUZ-REEL7 as Active and ROHS3 compliant.
