MAX4684/MAX4685 19-1977 Rev 3 2/03 0.5 /0.8 Low-Voltage, Dual SPDT Analog Switches in UCSP General Description Features 12-Bump, 0.5mm-Pitch UCSP The MAX4684/MAX4685 low on-resistance (R ), low- ON NC Switch R voltage, dual single-pole/double-throw (SPDT) analog ON 0.5 max (+2.7V Supply) (MAX4684) switches operate from a single +1.8V to +5.5V supply. 0.8 max (+2.7V Supply) (MAX4685) The MAX4684 features a 0.5 (max) R for its NC ON NO Switch R switch and a 0.8 (max) R for its NO switch at a ON ON 0.8 max (+2.7V Supply) +2.7V supply. The MAX4685 features a 0.8 max on- R Match Between Channels ON resistance for both NO and NC switches at a +2.7V 0.06 (max) supply.

The digi- ON OFF +1.8V to +5.5V Single-Supply Operation tal logic inputs are 1.8V logic-compatible with a +2.7V to Rail-to-Rail Signal Handling +3.3V supply. 1.8V Logic Compatibility The MAX4684/MAX4685 are packaged in the chipscale Low Crosstalk: -68dB (100kHz) package (UCSP), significantly reducing the required High Off-Isolation: -64dB (100kHz) PC board area. The chip occupies only a 2.0mm THD: 0.03% 1.50mm area. The 4 3 array of solder bumps are 50nA (max) Supply Current spaced with a 0.5mm bump pitch.

Limit forward-diode current to maximum current rating. Note 2: This device is constructed using a unique set of packaging techniques that impose a limit on the thermal profile the device can be exposed to during board level solder attach and rework. This limit permits only the use of the solder profiles recom- mended in the industry-standard specification, JEDEC 020A, paragraph 7.6, Table 3 for IR/VPR and Convection reflow. Pre- heating is required. Hand or wave soldering is not allowed. 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.
