The MAX4691/MAX4692/MAX4693 operate from either a single +2V to +11V power supply or dual ±2V to ±5.5V power supplies. When operating from ±5V supplies they offer 25Ω on-resistance (RON), 3.5Ω (max) RON flatness, and 3Ω (max) matching between channels. The MAX4694 operates from a single +2V to +11V supply. Each switch has Rail-to-Rail® signal handling and a low 1nA leakage current. All digital inputs are 1.8V logic-compatible when operating from a +3V supply and TTL compatible when operating from a +5V supply. The MAX4691–MAX4694 are available in 16-pin, 4mm ✕ 4mm QFN and 16-bump UCSP packages. The chip-scale package (UCSP™) occupies a 2mm x 2mm area, significantly reducing the required PC board area.

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.

EN is not present on the MAX4694. 2. C is not present on the MAX4692 and MAX4694. Detailed Description The MAX4691–MAX4694 are low-voltage CMOS analog ICs configured as an 8-channel multiplexer (MAX4691), two 4-channel multiplexers (MAX4692), three SPDT switches (MAX4693), and four SPDT switches (MAX4694). All switches are bidirectional. The MAX4691/MAX4692/MAX4693 operate from either a single +2V to +11V power supply or dual ±2V to ±5.5V power supplies. When operating from ±5V supplies they offer 25Ω on-resistance (RON), 3.5Ω max RON flatness, and 3Ω max matching between channels. The MAX4694 operates from a single +2V to +11V supply. Each switch has rail-to-rail signal handling, fast switching times of tON = 80ns, tOFF = 50ns, and a low 1nA leakage current. All digital inputs are 1.8V logic-compatible when operating from a +3V supply and TTL-compatible when operating from a +5V supply. Digital Inputs The MAX4691 and MAX4692 include address pins that allow control of the multiplexers. For the MAX4691, pins 12 A, B, C determine which switch is closed. The two 4-1 muxes in the MAX4692 are controlled by the same address pins (A and B). (Table 1) The MAX4693 and MAX4694 offer SPDT switches in triple and quadruple packages. In the MAX4693, each switch has a unique control input. The MAX4694 has two digital control inputs: A (for switches “W” and “Y”) and B (for switches “X” and “Z”). (Table 1) Applications Information Power-Supply Considerations Overview The MAX4691–MAX4694 construction is typical of most CMOS analog switches. V+ and V-* are used to drive the internal CMOS switches and set the limits of the analog voltage on any switch. Reverse ESD-protection diodes are internally connected between each analog signal pin and both V+ and V-. If any analog signal exceeds V+ or V-, one of these diodes will conduct. *V- is found only on the MAX4691/MAX4692/MAX4693. ______________________________________________________________________________________ Low-Voltage 8:1 Mux/Dual 4:1 Mux/Triple SPDT/ Quad SPDT in UCSP Package Virtually all the analog leakage current comes from the ESD diodes. Although the ESD diodes on a given signal pin are identical, and therefore fairly well balanced, they are reverse biased differently. Each is biased by either V+ or V- and the analog signal. This means their leakages will vary as the signal varies. The difference in the two diode leakages to the V+ and V- pins constitutes the analog signal path leakage current. All analog leakage current flows between each pin and one of the supply terminals, not to the other switch terminal. This is why both sides of a given switch can show leakage currents of either the same or opposite polarity. V+ and GND power the internal logic and logic-level translators, and set both the input and output logic limits. The logic-level translators convert the logic levels into switched V+ and V- signals to drive the gates of the analog signals. This drive signal is the only connection between the logic supplies (and signals) and the analog supplies. V+ and V- have ESD-protection diodes on GND. Bipolar Supplies The MAX4691/MAX4692/MAX4693 operate with bipolar supplies between ±2V and ±5.5V. The V+ and V- supplies need not be symmetrical, but their difference cannot exceed the absolute maximum rating of +12V. Single Supply These devices operate from a single supply between +2V and +11V when V- is connected to GND. All of the bipolar precautions must be observed. At room temperature, they operate with a single supply at near or below +2V, although as supply voltage decreases, switch on-resistance and switching times become very high. Always bypass supplies with a 0.1µF capacitor. Overvoltage Protection Proper power-supply sequencing is recommended for all CMOS devices. Do not exceed the absolute maximum ratings, because stresses beyond the listed ratings can cause permanent damage to the devices. Always sequence V+ on first, then V-, followed by the logic inputs and by W, X, Y, Z. If power-supply sequencing is not possible, add two small signal diodes (D1, D2) in series with the supply pins for overvoltage protection (Figure 1). Adding diodes reduces the analog signal range to one diode drop below V+ and one diode drop above V-, but does not affect the devices’ low switch resistance and low leakage characteristics. Device operation is unchanged, and the difference between V+ and Vshould not exceed 12V. These protection diodes are not recommended when using a single supply if signal levels must extend to ground. 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.
