CAPACITANCE TEST CIRCUIT Detailed Description The ISL84780 is a bidirectional, quad single pole/double throw (SPDT) analog switch that offers precise switching capability from a single 1.6V to 3.6V supply with low onresistance (0.36Ω) and high speed operation (tON = 12ns, tOFF = 8ns). The device is especially well suited for portable battery-powered equipment due to its low operating supply voltage (1.6V), low power consumption (5.4µW max), low leakage currents (30nA max), and the tiny TQFN and TSSOP packages. 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 8). To prevent forward biasing these diodes, V+ must be applied before any input signals, and the input signal 6 voltages must remain between V+ and GND. If these conditions cannot be guaranteed, then one of the following two protection methods should be employed. Logic inputs can easily be protected by adding a 1kΩ resistor in series with the input (See Figure 8). 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, so two small signal diodes can be added in series with the supply pins to provide overvoltage protection for all pins (See Figure 8). These additional diodes limit the analog signal from 1V below V+ to 1V above GND. The low leakage current performance is unaffected by this approach, but the switch signal range is reduced and the resistance may increase, especially at low supply voltages.

OVERVOLTAGE PROTECTION Power-Supply Considerations The ISL84780 construction is typical of most single supply 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 ISL84780 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 onresistance degrade at lower supply voltages. Refer to the electrical specification tables and Typical Performance curves for details. V+ and GND also power the internal logic and level shifters. The level shifters convert the input logic levels to switched V+ and GND signals to drive the analog switch gate terminals. This family of switches cannot be operated with bipolar supplies, because the input switching point becomes negative in this configuration. In 50Ω systems, the signal response is reasonably flat even past 30MHz with a -3dB bandwidth of 104MHz (See Figure 15). 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 feedthrough from the switch input to its output. Off Isolation is the resistance to this feedthrough, while Crosstalk indicates the amount of feedthrough from one switch to another. Figure 16 details the high Off Isolation and Crosstalk rejection provided by this part. At 100kHz, Off Isolation is about 68dB 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 switch family is 1.8V CMOS compatible (0.5V and 1.4V) over a supply range of 2.0V to 3.6V (See Figure 17). At 3.6V the VIH level is about 1.27V. This is still below the 1.8V CMOS guaranteed high output minimum level of 1.4V, 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 FN6099.1 December 27, 2004 ISL84780 Typical Performance Curves TA = 25°C, Unless Otherwise Specified 0.55 0.4 ICOM = 100mA 85°C 0.5 V+ = 1.8V 0.35 RON (Ω) RON (Ω) 0.45 0.4 25°C 0.3 V+ = 2.7V 0.35 -40°C V+ = 3V 0.3 V+ = 3.6V 0 1 2 3 0.25 4 V+ = 3V ICOM = 100mA 0 0.5 1 1.5 2 2.5 3 VCOM (V) VCOM (V) FIGURE 9.
