0.5 OHM, DUAL SPDT ANALOG SWITCH
DATASHEET
IDTAS4684
Description
The IDTAS4684 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 IDTAS4684
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 3 x 3 DFN, or 12-bump CSP packages.
Applications
• Speaker headset switching
• MP3 players
• Battery-operated equipment
• Audio and video signal routing
• PCMCIA cards
• Cellular phones
• Modems
Features
• +1.8 V to +5.5 V single-supply operation
• Rail-to-rail signal handling

Notes:
1. 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.
