The MAX312L/MAX313L/MAX314L analog switches have low on-resistance (up to 10Ω) and 1.5Ω on-resistance matching between channels. These switches are +3V logic compatible when powered from ±15V or +12V supplies. The switches conduct equally well in either direction and offer low leakage over temperature (2.5nA at +85°C). The MAX312L/MAX313L/MAX314L are quad, single-pole/single-throw (SPST) analog switches. The MAX312L is normally closed (NC), and the MAX313L is normally open (NO). The MAX314L has two normally closed switches and two normally open switches. All three devices operate from a single +4.5V to +36V supply or from dual ±4.5V to ±20V supplies and are available in 16-pin TSSOP, SO, and DIP packages.
The Maxim MAX312L, MAX313L, and MAX314L are quad single‑pole‑single‑throw (SPST) analog switches featuring low on‑resistance (10 Ω max) and 1.5 Ω channel‑to‑channel matching. They operate from a single‑supply voltage of +4.5 V to +36 V or a dual‑supply of ±4.5 V to ±20 V and are compatible with +3 V logic levels.
The datasheet provides detailed electrical characteristics, pin configurations for TSSOP, SO, DIP, and QFN packages, absolute maximum ratings, and application notes such as low‑distortion audio and power‑supply sequencing. Test circuit diagrams and typical performance graphs are included for designers.
