The MAX4130–MAX4134 family of operational amplifiers combines 10MHz gain-bandwidth product and excellent DC accuracy with Rail-to-Rail operation at the inputs and outputs. These devices require only 900µA per amplifier, and operate from either a single supply (+2.7V to +6.5V) or dual supplies (±1.35V to ±3.25V) with a common-mode voltage range that extends 250mV beyond VEE and VCC. They are capable of driving 250Ω loads and are unity-gain stable. In addition, the MAX4131/ MAX4133 feature a shutdown mode in which the outputs are placed in a high-impedance state and the supply current is reduced to only 25µA per amplifier.With their rail-to-rail input common-mode range and output swing, the MAX4130-MAX4134 are ideal for low-voltage, single-supply operation. Although the minimum operating voltage is specified at 2.7V, the devices typically operate down to 1.8V. In addition, low offset voltage and high speed make them the ideal signal-conditioning stages for precision, low-voltage data-acquisition systems. The MAX4130 is offered in the space-saving 5-pin SOT23 package. The MAX4131 is offered in the ultra-small 6-bump, 1mm x 1.5mm chip-scale package (UCSP™).ApplicationsAutomotive SensorsBase Station/Wireless InfrastructureBattery-Powered InstrumentsComputers: Desktops, Workstations, and ServersComputers: MotherboardsComputers: NotebookData Acquisition SystemsIndustrial: Process Measurement and ControlLow-Power, Low-Voltage ApplicationsPanel MetersPortable EquipmentProgrammable Logic Controllers (PLCs)Signal Conditioning

The MAX4172 is a low-cost, precision, high-side current-sense amplifier for portable PCs, telephones, and other systems where battery/DC power-line monitoring is critical. High-side power-line monitoring is especially useful in battery-powered systems, since it does not interfere with the battery charger's ground path. Wide bandwidth and ground-sensing capability make the MAX4172 suitable for closed-loop battery-charger and general-purpose current-source applications. The 0 to 32V input common-mode range is independent of the supply voltage, which ensures that current-sense feedback remains viable, even when connected to a battery in deep discharge.To provide a high level of flexibility, the MAX4172 functions with an external sense resistor to set the range of load current to be monitored. It has a current output that can be converted to a ground-referred voltage with a single resistor, accommodating a wide range of battery voltages and currents.An open-collector power-good output (active-low PG) indicates when the supply voltage reaches an adequate level to guarantee proper operation of the current-sense amplifier. The MAX4172 operates with a 3.0V to 32V supply voltage, and is available in a space-saving, 8-pin µMAX® or SO package.ApplicationsBattery-Powered ApplicationsClosed-Loop Battery Chargers/Current SourcesEnergy ManagementPortable PCs: Notebooks, Subnotebooks, PalmtopsPortable Test/Measurement SystemsPortable/Cellular PhonesSmart Battery Packs/Chargers
