The MAX4719 is a low-voltage, low on-resistance (RON), dual single-pole/double throw (SPDT) analog switch that operates from a single +1.8V to +5.5V supply. The MAX4719 features 20Ω RON (max) with 1.2Ω flatness and 0.4Ω matching between channels. The switch offers break-before-make switching (1ns) with tON <80ns and tOFF <40ns at +2.7V. The digital logic inputs are +1.8V logic compatible with a +2.7V to +3.6V supply. The switch is packaged in a chip-scale package (UCSP™), significantly reducing the required PC board area. The chip occupies only a 2.0mm × 1.50mm area and has a 4 × 3 bump array with a bump pitch of 0.5mm. The MAX4719 is also available in a 10-pin µMAX package.
The MAX4719 is a high‑speed, low‑voltage dual single‑pole/double‑throw (SPDT) analog switch that operates from a single +1.8 V to +5.5 V supply. It is offered in a chip‑scale UCSP package (2.0 mm × 1.5 mm) and a 10‑pin µMAX package, reducing board area for mobile and battery‑powered devices.
Key electrical characteristics include a maximum on‑resistance of 20 Ω, >300 MHz -3 dB bandwidth, break‑before‑make switching of 1 ns, turn‑on time <80 ns, turn‑off time <40 ns, off‑isolation of –55 dB at 10 MHz, crosstalk of –80 dB at 10 MHz, and total harmonic distortion of 0.03 %. The device is suited for cell phones, audio/video signal routing, low‑voltage data‑acquisition systems, and sample‑and‑hold circuits.
