... AC-coupled inputs. Additionally, four auxiliary outputs control additional circuitry via the MAX4550/MAX4570’s 2-wire or 3-wire interface. The MAX4550/MAX4570 feature 80Ω on-resistance, 10Ω on-resistance matching between channels, 5Ω on- resistance flatness, and 0.014% total harmonic distor- tion. Additionally, they feature off-isolation of at least ...

... Applications Information The MAX4550/MAX4570 are divided into five functional blocks: the control-logic block, two switch-matrix blocks, the bias-resistor block, and the auxiliary-output block (see Functional Diagram ). The control-logic block accepts commands via the serial interface and uses those commands to control the four remaining blocks ...

... LSB. While shifting data, the device remains in its original configuration. After all 16 bits are clocked into the input shift register, a rising edge on CS latches the data into the MAX4570 internal registers, initiating the device’s change of state. Start and Stop Conditions ...

... Addressable Serial Interface To program several MAX4570s individually using a sin- gle processor, connect DIN of each MAX4570 together and control CS on each MAX4570 separately. To select a particular device, drive the corresponding CS low, clock in the 16-bit command, then drive CS high and execute the command. Typically, only one MAX4570 is addressed at a time ...
