The MAX4914B/MAX4915A/B/MAX4917A/B family of switches feature internal current limiting to prevent damage to host devices due to faulty load conditions. These analog switches have a low 0.2Ω on-resistance and operate from a 2.3V to 5.5V input voltage range. They are available with guaranteed 100mA, 200mA, and 300mA current limits, making them ideal for SDIO and other load switching applications.When the switch is on and a load is connected to the port, a guaranteed blanking time of 14ms ensures that the transient voltages settle down. If after this blanking time the load current is greater than the current limit, the MAX4914B/MAX4915B/MAX4917B latchoff versions enter a latchoff state where the switch is turned off and active-low FLAG is issued to the microprocessor. The switch can be turned on again by cycling the power or the ON pin.The MAX4915A/MAX4917A have an autoretry feature where the switch turns off after the blanking time and then continuously checks to see if the overload condition is present. The switch turns on and remains on after the overload condition disappears and active-low FLAG deasserts.The MAX4914B is available in the tiny 6-pin µDFN (2mm x 2mm) package, while the MAX4915A/B and MAX4917A/B are available in both 6-pin µDFN (2mm x 2mm) and space-saving 5-pin SOT23 packages. These devices operate over the -40°C to +85°C extended temperature range.ApplicationsCell PhonesGPS SystemsHandheld DevicesNotebook ComputersPDAs and Palmtop DevicesSDIOUSB Ports

The dual MAX492, quad MAX494, and single MAX495 operational amplifiers combine excellent DC accuracy with rail-to-rail operation at the input and output. Since the common-mode voltage extends from VCCto VEE, the devices can operate from either a single supply (+2.7V to +6V) or split supplies (±1.35V to ±3V). Each op amp requires less than 150µA supply current. Even with this low current, the op amps are capable of driving a 1kΩ load, and the input referred voltage noise is only 25nV/√Hz. In addition, these op amps can drive loads in excess of 1nF.The precision performance of the MAX492/MAX494/MAX495, combined with their wide input and output dynamic range, low-voltage single-supply operation, and very low supply current, makes them an ideal choice for battery-operated equipment and other low-voltage applications. The MAX492/MAX494/MAX495 are available in DIP and SO packages in the industry-standard op-amp pin configurations. The MAX495 is also available in the smallest 8-pin SO: the µMAX® package.ApplicationsBattery-Powered ApplicationsData AcquisitionLow-Voltage ApplicationsPortable EquipmentSignal Conditioning
