Vishay expands CMOS analog switch/multiplexer line

Vishay Intertechnology Inc. expanded its DG92xx family of CMOS analog switching and multiplexer products with the introduction of four new devices designed for 2.7 V to 16 V single-supply or ± 2.7 V to ± 8 V dual-supply operation. The new devices combine their wide voltage range operation with compact package sizes and low-voltage logic compatibility for high-speed, high-precision switching applications.

The products 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). Applications include 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. 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.

At -3 dB, the multiplexers offer a bandwidth of 314 MHz (DG9251), 449 MHz (DG9252), and 480 MHz (DG9253) and provide 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.

Pricing: for U.S. delivery begins at $0.95 per piece for the DG9251 and DG9236 in 1,000-piece quantities and $1.25 per piece for the DG9252 and DG9253.

Availability: Samples and production quantities are available now, with lead times of 10 weeks for standard orders.
