ISL84516, ISL84517 ® Data Sheet June 2003 Low-Voltage, Dual Supply, SPST, Analog Switches The Intersil ISL84516 and ISL84517 devices are precision, analog switches designed to operate from ±1.5V to ±6V supplies. Targeted applications include battery powered equipment that benefit from the devices’ low power consumption (350mW), low leakage currents, and fast switching speeds. Additionally, excellent RON flatness maintains signal fidelity over the whole input range, while micro packaging alleviates board space limitations. The ISL8451X are single-pole/single-throw (SPST) switches, with the ISL84516 being normally open (NO), and the ISL84517 being normally closed (NC). Table 1 summarizes the performance of this family. For higher performance, pin compatible versions, see the ISL43112, ISL43113 data sheet. For single supply versions, see the ISL84514, ISL84515 data sheet. TABLE 1.

CAPACITANCE TEST CIRCUIT Detailed Description The ISL84516 and ISL84517 analog switches offer precise switching capability from ±1.5V to ±6V supplies with low onresistance (13Ω) and high speed operation (tON = 40ns, tOFF = 30ns). The devices are especially well suited to portable battery powered equipment thanks to the low operating supply voltage (±1.5V), low power consumption (350µW), low leakage currents (2nA max), and the tiny SOT-23 packaging. High frequency applications also benefit from the wide bandwidth, and the very high off isolation. 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 V- (see Figure 6). To prevent forward biasing these diodes, V+ and 5 V- must be applied before any input signals, and input signal voltages must remain between V+ and V-. 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 6). 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. 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 6). These additional diodes limit the analog signal from 1V below V+ to 1V above V-. The low leakage current performance is ISL84516, ISL84517 unaffected by this approach, but the switch resistance may increase, especially at low supply voltage. OPTIONAL PROTECTION DIODE V+ OPTIONAL PROTECTION RESISTOR IN Logic-Level Thresholds Due to the lack of a GND pin, the switching point of the digital input is referenced predominantly to V+. The digital input is CMOS compatible at ±5V supplies, and is TTL compatible for ±3.3V supplies. For other supply combinations refer to Figure 11. The switching point has a very low temperature sensitivity, and changes by only 100mV from 85oC to -40oC, regardless of supply voltage. VNO or NC VCOM High-Frequency Performance VOPTIONAL PROTECTION DIODE FIGURE 6. OVERVOLTAGE PROTECTION Power-Supply Considerations The ISL8451X construction is typical of most CMOS analog switches, except that there are only two supply pins: V+ and V-. The power supplies need not be symmetrical for useful operation. As long as the total supply voltage (V+ to V-, including supply tolerances, overshoot, and noise spikes) is less than the15V maximum supply rating, and the digital input switching point remains reasonable (see “Logic-Level Thresholds” section), the ISL84516, ISL84517 function well. The 15V maximum supply rating provides the designer of 12V systems much greater flexibility than switches with a 13V maximum supply voltage. The minimum recommended supply voltage is ±1.5V. It is important to note that the input signal range, switching times, and on-resistance degrade at lower supply voltages, and the digital input VIL becomes negative at VS ≤ ±2V. Refer to the “Typical Performance” curves for details. V+ and V- power the internal CMOS switches and set their analog voltage limits. These supplies also power the internal logic and level shifters. The level shifters convert the input logic levels to switched V+ and V- signals to drive the analog switch gate terminals. This family of switches is not recommended for single supply applications. For single supply, similar performance, pin compatible, TTL compatible versions of these switches, see the ISL84514, ISL84515 data sheet. 6 In 50Ω systems, signal response is reasonably flat to 30MHz, with a -3dB bandwidth of nearly 400MHz (see Figure 13). Figure 13 also illustrates that 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 a switch’s input to its output. OFF Isolation is the resistance to this feedthrough. Figure 14 details the high OFF Isolation provided by this family. At 10MHz, OFF Isolation is about 50dB in 50Ω systems, decreasing approximately 20dB per decade as frequency increases. Higher load impedances decrease OFF Isolation 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 V-. One of these diodes conducts if any analog signal exceeds V+ or V-. Virtually all the analog leakage current comes from the ESD diodes to V+ or V-. 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-signalpath 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 V-.
