MAX14759/MAX14761/MAX14763 are analog switches from Maxim Integrated Products. They can pass bipolar signals beyond their supply rails. They operate from a single +3.0V to +5.5V supply and support signals in the -25V to +25V range. MAX14759 is a single-pole/single-throw (SPST) analog switch, while the MAX14761 is a dual-SPST analog switch. The MAX14763 is a single-pole/double-throw (SPDT) analog switch. They feature 1Ω (max) on-resistance with a Q200nA (max) on-leakage current. The MAX14759/MAX14763 feature 2Ω (max) on-resistance with a Q100nA (max) on-leakage current. Their bandwidth is 5.1MHz. They are available in an 8-pin TDFN package. They are specified over the -40°C to +85°C extended temperature range.
The MAX14759, MAX14761, and MAX14763 are low on‑resistance analog switches that operate from a single supply rail of +3.0 V to +5.5 V and support bipolar signals from –25 V to +25 V. They are offered in 8‑pin and 10‑pin TDFN packages and include protections such as high‑ESD rating and thermal shutdown.
The datasheet provides absolute maximum ratings, detailed electrical characteristics (on‑resistance, leakage current, switch current, bandwidth), package thermal data, test circuit diagrams, typical operating curves, and ordering information for each part number.
