The MAX4696/MAX4697 are single-pole/single-throw (SPST) analog switches, and the MAX4698 is a single-pole/double-throw (SPDT) analog switch. The MAX4696 is a normally open (NO) switch, and the MAX4697 is a normally closed (NC) switch. When powered from a 2.7V supply, these devices feature 35Ω (max) RON, with 2Ω (max) RON matching and 13Ω (max) flatness. The MAX4696/MAX4697/MAX4698 offer fast switching speeds (tON = 80ns max, tOFF = 25ns max). The MAX4698 offers a break-before-make function. The digital logic inputs are 1.8V logic compatible from a +2.7V to +3.3V supply and are TTL/CMOS compatible from a +4.5V to +5.5V supply. The MAX4696/MAX4697/ MAX4698 are packaged in the chip-scale package (UCSP™), significantly reducing the required PC board area. The device occupies only a 1.50mm ✕ 1.02mm area. The 3 ✕ 2 array of solder bumps are 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 recommended in the industry standard specification, JEDEC 020A, paragraph 7.6, Table 3 for IR/VPR and convection reflow. Preheating 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.

Driving IN rail-to-rail minimizes power consumption. Logic inputs accept up to +5.5V regardless of supply voltage. Analog Signal Levels Analog signals that range over the entire supply voltage (GND to V+) are passed with very little change in R ON (see Typical Operating Characteristics). The switches are bidirectional, so the NO, NC, and COM terminals are both inputs or outputs. 6 NAME MAX4696 Ground Analog Switch, Normally Closed Terminal Analog Switch, Common Terminal Analog Switch, Normally Open Terminal Power-Supply Sequencing and Overvoltage Protection CAUTION: Do not exceed the absolute maximum ratings because stresses beyond the listed ratings may cause permanent damage to devices. Proper power-supply sequencing is recommended for all CMOS devices. Always apply V+ before applying analog signals, especially if the analog signal is not current limited. If this sequencing is not possible, and if the analog inputs are not current limited to <20mA, add a small-signal diode (D1) as shown in Figure 6. Adding a protection diode reduces the analog range to a diode drop (about 0.7V) below V+ (for D1). RON increases slightly at low supply voltages. Maximum supply voltage (V+) must not exceed +6V. Protection diode D1 also protects against some overvoltage situations.

UCSP Reliability The chip-scale package (UCSP) represents a unique package that greatly reduces board space compared to other packages. UCSP reliability is integrally linked to the user’s assembly methods, circuit board material, and usage environment. The user should closely review these areas when considering a UCSP. Performance through Operating Life Test and Moisture Resistance is equal to conventional package technology as it is primarily determined by the wafer-fabrication process. However, this form factor may not perform equally to a packaged product through traditional mechanical reliability tests. Mechanical stress performance is a greater consideration for a UCSP. UCSP solder joint contact integrity must be considered since the package is attached through direct solder contact to the user’s PC board. Testing done to characterize the UCSP reliability performance shows that it is capable of performing reliably through environmental stresses. Results of environmental stress tests and additional usage data and recommendations are detailed in the UCSP application note, which can be found on Maxim’s website, at www.maxim-ic.com.
