The MAX4550/MAX4570 serial-interface, programmable, dual 4x2 audio/video crosspoint switches are ideal for multimedia applications. Each device contains two identical crosspoint switch arrays, each with four inputs and two outputs. To improve off-isolation, use the additional crosspoint inputs SA and SB as shunts. Each output is selectively programmable for clickless or regular mode operation. A set of internal resistive voltage-dividers supplies DC bias for each output when using 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 distortion. Additionally, they feature off-isolation of at least -110dB in the audio frequency range and -78dB at 4MHz, with -95dB crosstalk in the audio frequency range and -54dB at 4MHz. The MAX4550 uses a 2-wire I²C-compatible serial interface, while the MAX4570 uses a 3-wire SPI™/QSPI™ or MICROWIRE™-compatible serial interface. These parts are available in 28-pin SSOP and wide SO packages and are tested over either the commercial (0°C to +70°C) or extended (-40°C to +85°C) operating temperature range.
