CROSSTALK TEST CIRCUIT Detailed Description The ISL54058 analog switches offer precise switching capability from a single 1.6V to 3.6V supply with low on-resistance (0.41Ω) and high speed operation (tRANS = 29ns). The device is especially well suited to portable battery powered equipment thanks to the low operating supply voltage (1.6V), low power consumption (0.17µW), low leakage currents (60nA max) , and the tiny µTQFN package. The ultra low on-resistance and RON flatness provide very low insertion loss and distortion to applications that require signal reproduction. Supply Sequencing And Overvoltage Protection With any CMOS device, proper power supply sequencing is required to protect the device from excessive input currents which might permanently damage the IC. All I/O pins contain ESD protection diodes from the pin to V+ and to GND (see Figure 7). To prevent forward biasing these diodes, V+ must 6 FIGURE 6. CAPACITANCE TEST CIRCUIT be applied before any input signals, and the input signal voltages must remain between V+ and GND. OPTIONAL SCHOTTKY DIODE V+ OPTIONAL PROTECTION RESISTOR ADDX Ax or Bx VCOMX GND OPTIONAL SCHOTTKY DIODE FIGURE 7. OVERVOLTAGE PROTECTION FN6380.0 September 29, 2006 ISL54058 If these conditions cannot be guaranteed, then precautions must be implemented to prohibit the current and voltage at the logic pin and signal pins from exceeding the maximum ratings of the switch. The following two methods can be used to provided additional protection to limit the current in the event that the voltage at a signal pin or logic pin goes below ground or above the V+ rail. Logic inputs can be protected by adding a 1kΩ resistor in series with the logic input (see Figure 7). The resistor limits the input current below the threshold that produces permanent damage, and the sub-microamp input current produces an insignificant voltage drop during normal operation. This method is not acceptable for the signal path inputs. Adding a series resistor to the switch input defeats the purpose of using a low RON switch. Connecting schottky diodes to the signal pins as shown in Figure 7 will shunt the fault current to the supply or to ground thereby protecting the switch. These schottky diodes must be sized to handle the expected fault current. Power-Supply Considerations The ISL54058 construction is typical of most CMOS analog switches, in that they have two supply pins: V+ and GND. V+ and GND drive the internal CMOS switches and set their analog voltage limits. Unlike switches with a 4V maximum supply voltage, the ISL54058 4.7V maximum supply voltage provides plenty of room for the 10% tolerance of 3.6V supplies, as well as room for overshoot and noise spikes. The minimum recommended supply voltage is 1.6V but the part will operate with a supply below 1.5V. It is important to note that the input signal range, switching times, and on-resistance degrade at lower supply voltages. Refer to the electrical specification tables and Typical Performance curves for details. V+ and GND power the internal logic (thus setting the digital switching point) and level shifters. The level shifters convert the logic levels to switched V+ and V- signals to drive the analog switch gate terminals. High-Frequency Performance In 50Ω systems, signal response is reasonably flat even past 10MHz with a -3dB bandwidth of 70MHz (see Figure 12). The frequency response is very consistent over a wide V+ range, and for varying analog signal levels. An OFF switch acts like a capacitor and passes higher frequencies with less attenuation, resulting in signal feed through from a switch’s input to its output. Off Isolation is the resistance to this feed through, while Crosstalk indicates the amount of feed through from one switch to another. Figure 11 details the high Off Isolation and Crosstalk rejection provided by this family. At 100kHz, Off Isolation is about 65dB in 50Ω systems, decreasing approximately 20dB per decade as frequency increases. Higher load impedances decrease Off Isolation and Crosstalk rejection due to the voltage divider action of the switch OFF impedance and the load impedance. Leakage Considerations Reverse ESD protection diodes are internally connected between each analog-signal pin and both V+ and GND. One of these diodes conducts if any analog signal exceeds V+ or GND. Virtually all the analog leakage current comes from the ESD diodes to V+ or GND. 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 GND 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 GND pins constitutes the analogsignal-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 the same or opposite polarity. There is no connection between the analog signal paths and V+ or GND. Logic-Level Thresholds This device is 1.8V CMOS compatible (0.5V and 1.4V) over a supply range of 2.7V to 3.6V. At 2.7V the VIL level is about 0.54V. This is still above the 1.8V CMOS guaranteed low output maximum level of 0.5V but noise margin is reduced. The digital input stages draw supply current whenever the digital input voltage is not at one of the supply rails. Driving the digital input signals from GND to V+ with a fast transition time minimizes power dissipation. 7 FN6380.0 September 29, 2006 ISL54058 Typical Performance Curves TA = +25°C, Unless Otherwise Specified 0.8 0.5 V+ = 3V ICOM = 100mA ICOM = 100mA 0.7 0.45 0.6 0.4 +85°C 0.35 +25°C RON (Ω) RON (Ω) V+ = 1.65V V+ = 1.8V 0.5 0.3 V+ = 2.7V 0.4 -40°C V+ = 3V 0.3 V+ = 3.6V 0 1 2 0.25 3 4 0 0.5 1 1.5 2 2.5 FIGURE 9.
