MAX4644 - High-Speed / Low-Voltage / 4 / SPDT CMOS Analog Switch

General Description

The MAX4644 is a single-pole/double-throw (SPDT) switch that operates from a single supply ranging from +1.8V to +5.5V.

It provides low 4Ω on-resistance (RON) as well as 1Ω RON flatness over the entire analog signal range.

Key Features

  • include low leakage currents over the entire temperature range, TTL/CMOS-compatible digital logic, and excellent AC characteristics. It is packaged in either a small 8-pin µMAX or a tiny 6-pin SOT23. Features o +1.8V to +5.5V Single-Supply Operation o Rail-to-Rail® Analog Signal Range o Guaranteed RON 4Ω max (+5V supply) 8Ω max (+3V supply) o +1.8V Operation RON 30Ω typ Over Temperature tON 18ns typ, tOFF 12ns typ o Guaranteed RON Flatness: 0.75Ω typ (+5V supply) o Guaranteed RON Match Between.

19-1657; Rev 0; 3/00 High-Speed, Low-Voltage, 4Ω, SPDT CMOS Analog Switch General Description The MAX4644 is a single-pole/double-throw (SPDT) switch that operates from a single supply ranging from +1.8V to +5.5V. It provides low 4Ω on-resistance (RON) as well as 1Ω RON flatness over the entire analog 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. It is packaged in either a small 8-pin µMAX or a tiny 6-pin SOT23. Features o +1.8V to +5.
