MAX14504/MAX14505/MAX14505A/MAX14506 19-4244 Rev 1 12/08 Dual SPDT Negative Rail Analog Switches with V Capability CC General Description Features The MAX14504/MAX14505/MAX14505A/MAX14506 Distortion-Free Negative Signal Throughput from dual single-pole/double-throw (SPDT) audio switches -V to +V CC CC feature negative signal capability that allows signals Internal Shunt Switches Reduce Click/Pop from -V to +V to pass without distortion. They fea- CC CC (MAX14505/MAX14505A) ture high continuous current ratings of 550mA (continu- ous) and 850mA (pulsed). These analog switches have Low On-Resistance 0.36 (typ) low on-resistance, low supply current, and operate from 1m (typ) On-Resistance Flatness a single +2.3V to +5.5V supply. COM High Impedance for EN = High The MAX14505/MAX14505A have internal shunt switches that discharge the audio amplifier AC-coupling capaci- Low 0.2A (max) Shutdown Current tance at the normally open (NO) terminals. This reduces (MAX14505A/MAX14506) click-and-pop sounds that occur when switching audio +2.3V to +5.5V Single-Supply Voltage signals between precharged points. The MAX14504/ MAX14505/MAX14505A/MAX14506 control the switches Small, 1.56mm x 2.14mm, 12-Bump WLP Package with control bit, CB, and feature an enable input, EN, that place COM in a high-impedance mode. Pin Configuration The MAX14504/MAX14505/MAX14505A/MAX14506 are fully specified to operate from a single +2.3V to +5.5V power supply. These devices are available in a 1.56mm x 2.14mm, 12-bump WLP package, and operate over MAX14504/ the -40C to +85C extended temperature range.

For EN V signals on NC , CC CC IH NO , and COM exceeding 0 or +V are clamped by internal diodes (MAX14505A/MAX14506). Limit forward-diode current CC to maximum current rating. Note 2: Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a 4-layer board. For detailed information on package thermal considerations, refer to www.maxim-ic.com/thermal-tutorial. Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. ELECTRICAL CHARACTERISTICS (V = +2.3 to +5.5V, T = T to T C = 3.3nF, unless otherwise noted.
