MAX14662ETI+

MAX14662ETI+ is a serially controlled 8 x SPST switch for general purpose signal switching applications. The number of switches makes the device useful in a wide variety of applications while serial control maximizes flexibility with minimal pins. This part features Beyond-The-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. Applications include audio switching/multiplexing, port protection, power management.

• VCC supply current of 300μA typ at VCC = +3.3V, all switches on
• Power supply rejection ratio of 80dB at RA = RB = 50 ohm, VCC = +3.3V ±0.1V, f = 10KHz
• I2C with two address-select pins, SPI with DOUT for daisy chain, independent control of each switch
• Beyond-the-rails, ±5.5V signal range independent of supply voltage
• Off-isolation is -40dB typ at RS = RL = 50 ohm, VA or VB = 0.60VP-P, f = 1MHz
• Total harmonic distortion plus noise is 0.001% typ at f = 20Hz to 20KHz, VA or VB = 0.50VP-P
• On-resistance is 0.425ohm typ at VCC > +1.8V
• On-resistance flatness is 0.005ohm at VCC = 3.3V, IB = 10mA, VB = -5.5V to +5.5V
• Operating temperature range from -40°C to 85°C
• 28 TQFN-EP package
