SPDT Dual Analog Signal Switch has 160 MHz bandwidth.
November 24, 2006 -
Model AS1746 SPDT low-voltage dual analog signal switch features maximum on-resistance of 0.5 W for normally closed line and 0.6 W for normally open line. Channel-to-channel matching is less than 0.06 W, and on-resistance flatness of 0.15 W allows total harmonic distortion to jutting 0.025%. Device is available in 10-pin TDFN as well as 10-bumps WL-CSP package and is suitable for operating environments ranging from -40 to +85°C.

austriamicrosystems Launches Low-Voltage, Dual 0.5 ohm SPDT Analog Switch for Audio Signals
AS1746 offers extremely low on-resistance combined with excellent flatness and matching making it ideal for audio signal switching
Unterpremstaetten, Austria (October 31, 2006) - austriamicrosystems (SWX: AMS), a leading global designer and manufacturer of analog integrated circuits (ICs) for communication, industrial, medical and automotive applications, further expanded its analog switch portfolio with the AS1746: a SPDT (singlepole/double-throw) low-voltage dual analog signal switch. This switch features outstanding low onresistance with a maximum of 0.5 ohm for the normally closed line and a maximum of 0.6 ohm for the normally opened line over the whole temperature range.
The AS1746 combines the extremely low on-resistance with an excellent channel-to-channel matching of less then 0.06 ohm, reducing the amount of signal deviations between switch channels to a minimum. A remarkable on-resistance flatness of 0.15 ohm guarantees a stable on-resistance over temperature or supply voltage variations. Altogether this improves the total harmonic distortion (THD+N) to jutting 0.025%.
"A switch needs to be as transparent as possible to the signal - low insertion loss and wide bandwidth are key. Low on-resistance flatness is essential for excellent total harmonic distortion (THD) so that there is no signal distortion, which is important for audio applications," said Walter Moshammer,
Director Marketing Standard Linear at austriamicrosystems. at austriamicrosystems. "austriamicrosystems' AS1746 addresses this need by offering outstanding THD+N combined with superb on-resistance, making this switch ideal for switching high quality audio signals."
The improved bandwidth of 160MHz makes the device ideal for data and audio signals. The combination of high off-isolation and the low crosstalk ensures excellent signal integrity. The low leakage current of 1nA reduces voltage offset. The wide supply voltage range from 1.8V to 5.5V supports a broad range of designs. All digital logic inputs are 1.8V CMOS compatible.
The AS1746 is available in a 10-pin TDFN (3x3mm) as well as in a 10-bumps WL-CSP package, suitable for operating environments ranging from -40 to +85°C.
