Power-Off Isolation (VCC=0V)
The FSA839 is a high-performance Single-Pole /
Double-Throw (SPDT) analog switch for audio
applications driven by low-voltage (1.8V) baseband
processors or ASICs. The device features ultra-low RON
of 0.8Ω (maximum) at 4.5V VCC and operates over the
wide VCC range of 1.65V to 5.5V. The device is
fabricated with sub-micron CMOS technology to
achieve fast switching speeds and is designed for
break-before-make operation.

The FSA839 interfaces between the low-voltage ASIC
and regular audio amplifiers and CODECs operating up
to a 5.5V supply range. The control circuitry allows for
1.8V (typical) signals on the control pin (Sel).

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device
reliability. The absolute maximum ratings are stress ratings only.

Notes:
2. On resistance is determined by the voltage drop between A and B pins at the indicated current through the switch.
3. ∆ RON=RON maximum – RON minimum; measured at identical VCC, temperature, and voltage.
4. Flatness is defined as the difference between the maximum and minimum value of on resistance over the
specified range of conditions.
5. Guaranteed by characterization, not production tested for VCC=1.65 – 1.95V.
