PRELIMINARY DATASHEET 0.5 OHM, DUAL SPDT ANALOG SWITCH Description The IDTAS4684A low on-resistance (RON), low voltage, dual single-pole/double-throw (SPDT) analog switch operates from a single +1.8 V to +5.5 V supply. The IDTAS4684A features a 0.5Ω (max) RON for its NC switch and a 0.8Ω (max) RON for its NO switch at a +2.7 V supply. It also features break-before-make switching action (2 ns) with tON = 50 ns and tOFF = 40 ns at +3 V. The digital logic inputs are 1.8 V logic-compatible with a +2.7 V to +3.3 V supply. Comes in a 12-bump CSP package.

The algebraic convention used in this data sheet is where the most negative value is a minimum and the most positive value a maximum. 2. UCSP parts are 100% tested at +25°C only and guaranteed by design and correlation at the full hot-rated temperature. 3. Guaranteed by design. 4. RON = RON(MAX) - RON(MIN), between NC1 and NC2 or between NO1 and NO2. 5. Flatness is defined as the difference between the maximum and minimum value of on resistance as measured over the specified analog signal ranges. 6. Off-isolation = 20log10 (VCOM / VCO), VCOM = output, VCO = input to off switch.
