DPDT Analog Switches
General Description
The MAX14689 ultra-small, low-on-resistance (R
Benefits and Features
● Distortion-Free Beyond-the-Rails Signaling
• Negative Voltage Audio and Video Signal Capable
• -5.5V to +5.5V Analog Signal Range Independent
)
ON
double-pole/double-throw (DPDT) analog switches fea-
ture Beyond-the-Rails™ capability that allows signals
from -5.5V to +5.5V to pass without distortion, even when
the power supply is below the signal range. The low on-
resistance (0.25Ω) also makes the device ideal for low-
distortion switching applications, such as audio or video.
from V
CC
• On-Resistance 0.25Ω (typ)
• +1.6V to +5.5V Single-Supply Range
• Total Harmonic Distortion Plus Noise 0.001% (typ)
• On-Resistance Flatness 0.001Ω (typ)
The MAX14689 is fully specified to operate from a single
+1.6V to +5.5V power supply. Because of the low supply
● Low Supply Current 40µA (typ) at 1.6V
• Can be Powered by GPIO
• High-Impedance Mode when V
current requirement, V
can be provided by a GPIO.
CC
Not Applied
When power is not applied, the switches go to a high-
impedance mode and all analog signal ports can with-
stand signals from -5.5V to +5.5V. The switch is controlled
with a single control bit, CB.
