EVALUATION KIT AVAILABLE MAX14661 Beyond-the-Rails 16:2 Multiplexer General Description Features and Benefits Beyond-the-Rails Technology Reduces Cost and The MAX14661 is a serially controlled, dual-channel Complexity analog multiplexer allowing any of the 16 pins to be Switch 5.5V Signals from a +1.6V Single Supply connected to either common pin simultaneously in any TM Wide +1.6V to +5.5V Supply Range combination. The device features Beyond-the-Rails Low 5.5 W R (typ) Across the Supply Range capability so that 5.5V signals can be passed with any ON single supply between +1.6V and +5.5V. Flexible Multiplexing Enable s Design Reuse 16:2 Matrix Switch Multiplexer Connects Any Input 2 The serial control is selectable between I C and SPI. Pin To Either Common Pin In Any Combination Both modes provide individual control of each indepen- 2 Each Switch is Independently Controlled via I C or dent switch so that any combination of switches can SPI 2 be applied. I C mode provides two address-select pins Programmable Shadow Registers Allow allowing for addressing up to four devices on a single bus. Simultaneous Updating The SPI mode includes a DOUT pin that can be used to Low Distortion Switching Improves System chain multiple devices together with a single select signal. Performance The IC is available in a 28-pin (4mm x 4mm) TQFN pack- Total Harmonic Distortion + Noise 0.005% (typ) age and is specified over the -40C to +85C extended R Flatness 2.5m (typ) Across Complete ON temperature range. The AB and COM pins provide Signal Range 10kV ESD protection (HBM). Integrated Protection for System Reliability 10kV HBM ESD Protection on all AB and COM Applications Pins, Even When Powered Down System Diagnostics Data Acquisition Ordering Information appears at end of data sheet. 2 I C Signal Switching Audio Input Selection Beyond-the-Rails is a trademark Maxim Integrated Products, Inc. 19-6739 Rev 2 1/15MAX14661 Beyond-the-Rails 16:2 Multiplexer Functional Diagram MAX14661 COMA AB01 AB02 AB03 AB04 AB05 AB06 AB07 AB08 AB09 AB10 AB11 AB12 AB13 AB14 AB15 AB16 COMB SCLK/SCL V CC DIN/SDA GND SERIAL CONTROL 2 CS/A0 SPI/I C DOUT/A1 SD
