Fast switching speeds, low ON-resistance, and low power consumption make these devices ideal for singlecell battery powered applications. These highly-reliable devices operate from a single +1.6 to +3.6V supply, and are differentiated by the type and number of switches: ! ! ! 2 Key Features ! ON-Resistance: - 0.9Ω (+3V supply) - 2.5Ω (+1.8V supply) RON Matching: - 0.12Ω (+3V supply) - 0.25Ω (+1.8V supply) RON Flatness: 0.1Ω (+3V Supply) Supply Voltage Range: +1.6 to +3.6V Switching Speed: tON = 22ns, tOFF = 14ns Current-Handling: 250mA Continuous Break-Before-Make Switching (AS1753) Rail-to-Rail Signal Handling 1.8V CMOS Logic Compatible (+3V Supply) Operating Temperature Range: -40 to +85ºC Package Types: - 16-pin TQFN (3mm x 3mm) - 14-pin TSSOP ! ! ! ! ! ! ! ! AS1751 – Four normally open (NO) switches AS1752 – Four normally closed (NC) switches AS1753 – Two NO switches and Two NC switches The AS1753 supports break-before-make switching. With very low ON-resistance (RON), RON matching and RON flatness, the devices can accurately switch signals for sample and hold circuits, digital filters, and op-amp gain switching networks. The AS1751/AS1752/AS1753 digital logic input is 1.8V CMOS-compatible when using a +3V supply, and all devices can handle Rail-to-Rail signals. The devices are available in a 3mm x 3mm 16-pin TQFN package and a 14-pin TSSOP package.

Bi-Directional Switching Pins NOx, NCx, and COMx are bi-directional, thus they can be used as inputs to- or outputs from other components. Analog Signal Levels Analog signals ranging over the entire supply voltage range (V+ to GND) can be switched with very little change in ONresistance (see Typical Operating Characteristics on page 6). Logic Inputs The devices’ logic inputs can be driven up to +3.6V regardless of the supply voltage value. For example, with a +1.8V supply, INx may be driven low to GND and high to +3.6V. This allows the devices to interface with +3V systems using a supply of less than 3V. www.austriamicrosystems.com Revision 1.41 5 IN3 6 GND 7 NO3 8 COM3 8 - 16 AS1751/AS1752/AS1753 Data Sheet - A p p l i c a t i o n I n f o r m a t i o n 9 Application Information Power Supply Sequencing Proper power-supply sequencing is critical for proper switch operation. The power supplies should be started up in the following sequence: 1. V+ 2. NOx, NCx, COMx Note: Do not exceed the absolute maximum ratings (see page 2). Overvoltage Protection ON-resistance increases slightly at lower supply voltages. Figure 12. Overvoltage Protection using 2 External Blocking Diodes AS1751/AS1752/AS1753 D1 V+ V+ COMx VGEN NOx GND D2 Adding diode D2 to the circuit shown in Figure 12 causes the logic threshold to be shifted relative to GND. Diodes D1 and D2 also protect against overvoltage conditions. For example, in the circuit shown in Figure 12, if the supply voltage goes below the absolute maximum rating, and if a fault voltage up to the absolute maximum rating is applied to an analog signal pin, no damage will result. Power Supply Bypass Power supply connections to the devices must maintain a low impedance to ground. This can be done using a bypass capacitor, which will also improve noise margin and prevent switching noise propagation from the V+ supply to other components. A 0.1µF bypass capacitor, connected from V+ to GND (see Figure 18 on page 11), is adequate for most applications. Logic Inputs Driving INx Rail-to-Rail will help minimize power consumption. Layout Considerations High-speed switches require proper layout and design procedures for optimum performance. ! ! ! Short, wide traces should be used to reduce stray inductance and capacitance. Bypass capacitors should be as close to the device as possible. Large ground planes should be used wherever possible. www.austriamicrosystems.com Revision 1.41 9 - 16 AS1751/AS1752/AS1753 Data Sheet - A p p l i c a t i o n I n f o r m a t i o n Timing Diagrams and Test Setups Figure 13.
