PRELIMINARY DATASHEET
0.5Ω LOW VOLTAGE, SINGLE SPDT ANALOG SWITCH
IDTAS4624
Description
The IDTAS4624 low on-resistance (RON), low voltage,
single-pole/double-throw (SPDT) analog switch operates
from a single +1.8 V to +5.5 V supply. The IDTAS4624
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 input
is 1.8 V logic-compatible with a +2.7 V to +3.3 V supply.
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
• 1.8 V logic compatibility
• RON match between channels: 0.06Ω (max)
• RON flatness over signal range: 0.15Ω (max)
• NCx Switch RON: 0.5Ω max (+2.7 V Supply) (ICSAS4684)
• NOx Switch RON: 0.8Ω max (+2.7 V Supply)
• Low crosstalk: -68dB (100 kHz)
• High Off-isolation: -64dB (100 kHz)
• THD: 0.03%
• 50 nA (max) supply current
• Low leakage currents: 1 nA (max) at TA = +25°C
• 6-pin SOT-23 package

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.

Notes:
1. “Z” is the device step (1 to 2 characters).
2. YYWW is the last two digits of the year and week that the part was assembled.
3. “$” is the assembly mark code.
4. “G” after the two-letter package code designates RoHS compliant package.
5. “I” at the end of part number indicates industrial temperature range.
6. Bottom marking: country of origin if not USA.
