MAX4729/MAX4730 are single-pole / double-throw (SPDT) switches that operate from a single supply voltage of +1.8V to +5.5V. At +2.7V supply, these switches feature a low on-resistance (RON) of 3.5Ω and RON flatness of 0.45Ω. Typical operation draws only 1nA of supply current, making them ideal for low-power portable applications. MAX4729/MAX4730 have low leakage current over the entire extended temperature range and feature TTL/CMOS compatible digital logic and excellent AC characteristics.
The MAX4729 and MAX4730 are single‑pole double‑throw (SPDT) analog switches that operate from a single supply of +1.8 V to +5.5 V. They feature a low on‑resistance of 3.5 Ω at a 2.7 V supply and a flatness of 0.45 Ω across the specified range, making them suitable for low‑power portable applications.
The devices are offered in compact 6‑pin SC70 and µDFN packages and support TTL/CMOS compatible digital logic. They provide low leakage currents (typical 1 nA) and exhibit good AC performance, including a -3 dB bandwidth of 300 MHz and low on‑capacitance (19.5 pF). This manual is written in Chinese.
