MAX4321

Low-Cost, Low-Voltage, Rail-to-Rail, Input/Output, SOT23 5MHz Op Amp

Low-Voltage, Pin-for-Pin Upgrade for LMC7101


Please check latest availability status for a specific part variant.

Description

The MAX4321 operational amplifier (op amp) combines a 5MHz gain-bandwidth product and excellent DC accuracy with rail-to-rail operation at both the inputs and the output. This device requires only 650µA and operates from either a single +2.4V to +6.5V supply or dual ±1.2V to ±3.25V supplies, although the MAX4321 typically operates down to +1.8V (±0.9V). The MAX4321 remains unity-gain stable with capacitive loads up to 500pF and is capable of driving 250Ω loads to within 200mV of either rail.

With rail-to-rail input common-mode range and output swing, the MAX4321 is ideal for low-voltage, single-supply applications. In addition, low ±1.2mV input offset voltage and high 2V/µs slew rate make this device ideal for signal-conditioning stages for precision, low-voltage data-acquisition systems. The MAX4321 comes in a space-saving 5-pin SOT23 package and is guaranteed over the extended (-40°C to +85°C) temperature range.

The MAX4321 is a low-voltage, pin-for-pin compatible upgrade for the LMC7101 that offers five-times higher bandwidth, two-times faster slew rate, and about half the input voltage noise density.
