MAX14661ETI+

The MAX14661ETI+ is a beyond the rails 16:2 multiplexer in 28 pin TQFN package. This serially controlled, dual channel analogue multiplexer allowing any of 16 pins to be connected to either common pin simultaneously in any combination. The device features beyond rails capability so that ±5.5V signals can be passed with any single supply between +1.6V and +5.5V. The serial control is selectable between I2C and SPI. Both modes provide individual control of each independent switch so that any combination of switches can be applied. I2C mode provides two address select pins allowing for addressing up to four devices on a single bus. The SPI mode includes a DOUT pin that can be used to chain multiple devices together with a single select signal. It is used in system diagnostics, data acquisition, I2C signal switching and audio input selection.

• Supply voltage range is 1.6V to 5.5V
• Operating temperature range from -40°C to 85°C
• Beyond the rails technology reduces cost & complexity, low 5.5W RON (typ) across supply range
• Flexible multiplexing enables design reuse
• 16:2 matrix switch multiplexer connects any input pin to either common pin in any combination
• Each switch is independently controlled via I2C or SPI
• Programmable shadow registers allow simultaneous updating
• Low distortion switching improves system performance, total harmonic distortion + noise 0.005% (typ)
• RON flatness 2.5mohm (typ) across complete signal range
• Integrated protection, ±10KV HBM ESD protection on all AB_ and COM_ Pins, even when powered down
