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 +1.8 to +5.5V supply, are differentiated by inverted logic, and support break-before-make switching. With 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 devices are available in a 10-pin MSOP package and a 10-pin TDFN package. 2 Key Features !

CMOS process technology allows switching of analog signals that are within the supply voltage range (GND to V+). ON-Resistance When powered from a +5V supply, the low RON (4Ω max) allows high continuous currents to be switched in a wide range of applications. All devices have low RON flatness (1Ω, max) so they can meet or exceed the low-distortion audio requirements of modern portable audio devices. Bi-Directional Switching Pins NOx, NCx, and COMx are bi-directional, thus they can be used as inputs or outputs. Analog Signal Levels Analog signals ranging over the entire supply voltage (V+ to GND) can be passed with very little change in ON-resistance (see Typical Operating Characteristics on page 5). Logic Inputs The AS1744/AS1745 logic inputs (INx) can be driven up to +5.5V regardless of the supply voltage value. For example, with a +3.3V supply, IN+ may be driven low to GND and high to +5.5V. This allows the devices to interface with +5V systems using a supply of less than 5V. www.austriamicrosystems.com Revision 1.53 6 - 16 A S1744, AS1745 Data Sheet austria m i c r o systems Power-Supply Sequencing 8 Application Information Power-Supply Sequencing Proper power-supply sequencing is critical for proper operation. The recommended sequence is as follows: 1. V+ 2. NOx, NCx, COMx Always apply V+ before applying analog signals, especially if the analog signal is not current-limited. If the above sequence is not possible, and if the analog inputs are not current-limited to less than 30mA, add a small-signal diode as shown in Figure 10 (D1). If the analog signal can dip below GND, add diode D2. Adding these diodes will reduce the analog range to a diode-drop (about 0.7V) below V+ (for D1), and a diode-drop above ground (for D2). Note: Operation beyond the absolute maximum ratings (see page 2) may permanently damage the devices. Overvoltage Protection ON-resistance increases slightly at lower supply voltages. Figure 10. Overvoltage Protection Using 2 External Blocking Diodes AS1744/AS1745 V+ D1 V+ NOx VGEN COMx GND D2 Adding diode D2 to the circuit shown in Figure 10 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 10, 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. Note: The supply voltage (V+) must not exceed the absolute maximum rating of +7V. 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. Layout Considerations High-speed switches require proper layout and design procedures for optimum performance. ! ! ! Reduce stray inductance and capacitance by keeping traces short and wide. Ensure that bypass capacitors are as close to the device as possible. Use large ground planes where possible. www.austriamicrosystems.com Revision 1.53 7 - 16 A S1744, AS1745 Data Sheet austria m i c r o systems Timing Diagrams and Test Setups Timing Diagrams and Test Setups Figure 11.
