2.7V-16 V single-supply and ± 2.7V-±8 V dual-supply range CMOS analog switch and multiplexers

Vishay Intertechnology, Inc. has added four new devices designed for 2.7 V to 16 V single-supply or ± 2.7 V to ± 8 V dual-supply operation to its DG92xx family of CMOS analog switching and multiplexer products.

The products released include a dual SPDT analog switch (DG9236), an 8-channel multiplexer (DG9251), a dual 4-channel multiplexer (DG9252), and a triple 2-channel multiplexer (DG9253). The new devices are suggested for touch panels, tablets, data acquisition, healthcare, instrumentation, and automation equipment.

The DG9251, DG9252, and DG9253 are fully specified at + 16 V, + 5 V and ± 5 V and compatible with CMOS and GPIO control signals. The devices' control inputs have guaranteed 1.4 V logic high when operating from + 5 V or ± 5 V supplies, and 1.65 V logic high when operating from a + 16 V supply. For CMOS/TTL microprocessor control signals, the DG9236 has a guaranteed 1.8 V logic high when operating from a +16 V power supply.

The three multiplexers are offered in the compact 1.8 mm by 2.6 mm miniQFN-16 package, while the DG9236 analog switch is offered in the 1.4 mm by 1.8 mm miniQFN-10 package with a low 0.55 mm profile. The devices' plastic miniQFN packages are the smallest in the industry, and are comparable to WCSP type packages, as per Vishay.

At - 3 dB, the multiplexers provide a bandwidth of 314 MHz (DG9251), 449 MHz (DG9252), and 480 MHz (DG9253), and provide excellent isolation performance of - 45 dB (typical) at 100 MHz and crosstalk of - 48 dB (typical) at 100 MHz. The DG9236 features a bandwidth of 800 MHz and - 70 dB crosstalk and - 62 dB off-isolation at 10 MHz. All four devices are specified for an operating temperature range of - 40 °C to + 85 °C.

Availability: Samples and production quantities of the new analog switch and multiplexers are available now, with lead times of 10 weeks for standard orders.Vishay Intertechnology, Inc. has added four new devices designed for 2.7 V to 16 V single-supply or ± 2.7 V to ± 8 V dual-supply operation to its DG92xx family of CMOS analog switching and multiplexer products.
