MAXIM INTEGRATED / ANALOG DEVICES MAX4321EUKT Low-Voltage Rail-to-Rail Op Amp

The MAX4321EUK+T is a low-cost, low-voltage operational amplifier in a 5-pin SOT-23 package. It offers a gain-bandwidth product of 5MHz, excellent DC accuracy, and rail-to-rail input/output operation. Operating from a single supply voltage of +2.4V to +6.5V or dual supplies of ±1.2V to ±3.25V, it typically functions down to +1.8V (±0.9V). The op-amp remains stable with capacitive loads up to 500pF and can drive 250-ohm loads within 200mV of the rails. Its low input offset voltage (around ±1.2mV), high slew rate (2V/µs), and rail-to-rail input/output make it ideal for precision signal conditioning in low-voltage, single-supply applications, especially in data acquisition systems. It is pin-compatible with the LMC7101 IC, operates over -40°C to 85°C, and features no phase reversal for overdriven inputs.
