The MAX4414–MAX4419 operational amplifiers combine high-speed performance, low distortion, and ultra-low supply current. Consuming just 1.6mA of supply current per amplifier, these devices operate from a single +2.7V to +5.5V supply, have rail-to-rail outputs, and exhibit a common-mode input voltage range that extends from 100mV below ground to within 1.5V of the positive supply rail.The MAX4414/MAX4416/MAX4418 single/dual/quad op amps are unity-gain stable and achieve a 400MHz -3dB bandwidth with a 200V/µs slew rate. The MAX4415/MAX4417/MAX4419 single/dual/quad op amps are compensated for closed-loop gains of +5V/V or greater and achieve a 150MHz -3dB bandwidth with a 470V/µs slew rate. The combination of high-speed, ultra-low power, and low-distortion makes the MAX4414–MAX4419 ideal for low-power/low-voltage, high-speed portable systems such as video, communications, and instrumentation.The MAX4414/MAX4415 single and MAX4416/MAX4417 dual amplifiers are available in space-saving 8-pin µMAX® and SO packages, while the MAX4418/MAX4419 quad amplifiers are available in a 14-pin TSSOP package.ApplicationsAudio SystemsBaseband ApplicationsBattery-Powered ApplicationsKeyless EntryPortable CommunicationsVideo Line Driver

The MAX44281 is the industry's first op amp in a 4-bump WLP package, designed for use in portable consumer and medical applications. This device is offered as a noninverting amplifier with gain (AV) of +1V/V, +2V/V, or +10V/V.The device features rail-to-rail output, low 100µV input voltage offset, and 15MHz of bandwidth with only 700µA of supply current.The device features shutdown functionality by pulling VDDto ground. During shutdown, both the input and the output are high impedance.The device is available in an ultra-small, 0.85mm x 0.85mm, 4-bump WLP package with 0.5mm height. It is specified over the -40°C to +125°C temperature range.Applications3G/4G HandsetsBattery-Powered DevicesGeneral-Purpose Signal ProcessingNotebooksPortable Medical DevicesSensor InterfacesTransimpedance Amplifiers

The MAX44241/MAX44243/MAX44246 are 36V, ultra- precision, low-noise, low-drift, single/quad/dual opera- tional amplifiers that offer near-zero DC offset and drift through the use of patented chopper stabilized and auto-zeroing techniques. This method constantly mea- sures and compensates the input offset, eliminating drift over time and temperature and the effect of 1/f noise. These single/quad/dual devices feature rail-to-rail out- puts, operate from a single 2.7V to 36V supply or dual ±1.35V to ±18V supplies, and consume only 0.42mA per channel, with only 9nV/√Hz input-referred voltage noise.The ICs are available in 8-pin µMAX®or SO packages and are rated over the -40°C to +125°C temperature range.ApplicationsBattery-Powered EquipmentLoad Cell AmplifiersPLC Analog I/O ModulesPrecision InstrumentationTransducer Amplifiers

The MAX44242 provides a combination of high voltage, low noise, low input bias current in a dual channel and features rail-to-rail at the output.This dual amplifier operates over a wide supply voltage range from a single 2.7V to 20V supply or split ±1.35V to ±10V supplies and consumes only 1.2mA quiescent supply current per channel.The MAX44242 is a unity-gain stable amplifier with a gain-bandwidth product of 10MHz. The device outputs drive up to 200pF load capacitor without any external isolation resistor compensation.The MAX44242 is available in 8-pin SOT23 and µMAX®packages and is rated for operation over the -40°C to +125°C automotive temperature range.Design Solution: The Incredible Shrinking Encoder ›ApplicationsChemical Sensor InterfaceIndustrial: Process and ControlMedical Pulse OximetryPhotodiode Sensor InterfacePrecision Instrumentation
