Product details

Quad SPDT switch with 45 Ω on-resistance and 5 Ω channel matching

The ADG333ABRZ from Analog Devices is a quad SPDT (2:1) analog switch array in a 20-SOIC package. Each of the four independent switches carries a maximum on-resistance of 45 Ω, with channel-to-channel matching held to 5 Ω — tight enough that gain error across a multi-channel multiplexed front-end stays within a fraction of a percent without external trim. Switching is specified at 90 ns turn-on and 80 ns turn-off typical, fast enough for audio-band multiplexing and moderate-speed data acquisition. The part runs from a single supply of 3 V to 30 V or dual supplies of ±3 V to ±20 V, so it fits both single-rail and bipolar signal chains. Charge injection is 2 pC, low enough to avoid noticeable glitch feedthrough into a sample-and-hold or ADC input.

Crosstalk and leakage — what they mean for your signal path

Crosstalk is specified at -85 dB at 1 MHz. Off-channel leakage current is 250 pA maximum.

Package and supply flexibility

The 20-SOIC wide-body package (0.295 inch, 7.50 mm width) is a standard footprint. Surface-mount only, supplied in tube.

Frequently asked questions

Is ADG333ABRZ equivalent to ADG333A?

The ADG333ABRZ is the standard tube-packaged variant of the ADG333A family. The -ABRZ suffix indicates the wide-body 20-SOIC tube format; the -ABRSZ suffix is the same die in a different tube configuration, and -REEL suffixes are tape-and-reel. All share the same 45 Ω on-resistance, -85 dB crosstalk, and 2 pC charge injection.

Can ADG333ABRZ operate from a single 5V supply?

Yes, the single-supply range is 3 V to 30 V, so a 5 V rail is well within the operating window. The on-resistance and switching speed will be slightly higher at 5 V than at ±15 V, but the part is fully functional and specified across that range.

What is ADG333ABRZ's listed crosstalk?

Crosstalk is specified at -85 dB at 1 MHz, which means less than 0.006 % feedthrough between channels at that frequency.
