The MAX4322/MAX4323/MAX4326/MAX4327/MAX4329 family of operational amplifiers combines wide bandwidth and excellent DC accuracy with rail-to-rail operation at the inputs and outputs. These devices consume only 650µA per amplifier and operate from either a single supply (2.4V to 6.5V) or dual supplies (±1.2V to ±3.25V). These unity-gain-stable amplifiers are capable of driving 250Ω loads and have a 5MHz gain-bandwidth product. The MAX4323 and MAX4327 feature a low-power shutdown mode that reduces supply current to 25µA and places the outputs in a high-impedance state.With their rail-to-rail input common-mode range and output swing, these amplifiers are ideal for low-voltage, single-supply operation. In addition, low offset voltage and high speed make them the ideal signal-conditioning stages for precision, low-voltage data-acquisition systems.The MAX4323 is offered in a small 6-bump chip-scale package (UCSP™). The MAX4322/MAX4323 are also available in space-saving SOT23 packages.ApplicationsAutomotive SensorsBase Station/Wireless InfrastructureBattery-Powered InstrumentsComputers: Desktops, Workstations, and ServersComputers: MotherboardsComputers: NotebookData Acquisition SystemsGPS SolutionsLow-Power, Low-Voltage ApplicationsMP3 Docking Stations: Mid LevelPA BiasingPortable EquipmentProgrammable Logic Controllers (PLCs)RSSI SystemsSet-Top BoxesSignal Conditioning

The MAX4335–MAX4338 op amps deliver 40mW per channel into 32Ω from ultra-small SC70/SOT23 packages making them ideal for mono/stereo headphone drivers in portable applications. These amplifiers have a 5MHz gain-bandwidth product and are guaranteed to deliver 50mA of output current while operating from a single supply of 2.7V to 5.5V.The MAX4336 and the MAX4338 have a shutdown/mute mode that reduces the supply current to 0.04µA per amplifier and places the outputs in a high-impedance state.The MAX4335–MAX4338 have 90dB power-supply rejection ratio (PSRR), eliminating the need for costly preregulation in most audio applications. Both the input voltage range and the output voltage swing include both supply rails, maximizing dynamic range.The MAX4335/MAX4336 single amplifiers are available in ultra-small 6-pin SC70 packages. The MAX4337/MAX4338 dual amplifiers are available in an 8-pin SOT23 and a 10-pin µMAX® package, respectively. All devices are specified from -40°C to +85°C.Applications32Ω Headphone DriversDAC/ADC BuffersHands-Free Car PhonesPortable Battery-Powered InstrumentsTransformer/Line DriversWireless PA Control

The MAX4330–MAX4334 single/dual/quad op amps combine a wide 3MHz bandwidth, low-power operation, and excellent DC accuracy with rail-to-rail inputs and outputs. These devices require only 245µA per amplifier, and operate from either a single +2.3V to +6.5V supply or dual ±1.15V to ±3.25V supplies. The input common-mode voltage range extends 250mV beyond VEEand VCC, and the outputs swing rail-to-rail. The MAX4331/MAX4333 feature a shutdown mode in which the output goes high impedance and the supply current decreases to 9µA per amplifier.Low-power operation combined with rail-to-rail input common-mode range and output swing makes these amplifiers ideal for portable/battery-powered equipment and other low-voltage, single-supply applications. Although the minimum operating voltage is specified at 2.3V, these devices typically operate down to 2.0V. Low offset voltage and high speed make these amplifiers excellent choices for signal-conditioning stages in precision, low-voltage data-acquisition systems. The MAX4330 is available in the space-saving 5-pin SOT23 package, and the MAX4331/MAX4333 are offered in a µMAX® package.ApplicationsAutomotive SensorsBase Station/Wireless InfrastructureComputers: Desktops, Workstations, and ServersComputers: MotherboardsComputers: NotebookData AcquisitionGPS SolutionsLow-Power, Low-Voltage ApplicationsMP3 Docking Stations: Mid LevelPortable Battery-Powered EquipmentProgrammable Logic Controllers (PLCs)Set-Top BoxesSignal Conditioning
