MAX4644EUA+

The MAX4644EUA+ is a high speed, low voltage, 4ohm, SPDT CMOS analogue switch in 8 pin µMAX package. It provides low 4ohm on-resistance (RON) as well as 1ohm RON flatness over the entire analogue signal range. The MAX4644 offers fast switching times of less than 20ns while ensuring break before make operation. It typically consumes only 0.01μW of quiescent power making it suitable for use in low power portable applications. The MAX4644’s features include low leakage currents over the entire temperature range, TTL/CMOS-compatible digital logic and excellent AC characteristics. Typical applications include battery operated equipment, audio and video signal routing, low voltage data acquisition systems, sample and hold circuits.
