The MAX4450 single and MAX4451 dual op amps are unity-gain-stable devices that combine high-speed performance with rail-to-rail outputs. Both devices operate from a +4.5V to +11V single supply or from ±2.25V to ±5.5V dual supplies. The common-mode input voltage range extends beyond the negative power-supply rail (ground in single-supply applications). The MAX4450/MAX4451 require only 6.5mA of quiescent supply current per op amp while achieving a 210MHz -3dB bandwidth and a 485V/µs slew rate. Both devices are an excellent solution in low-power/low-voltage systems that require wide bandwidth, such as video, communications, and instrumentation. The MAX4450 is available in the ultra-small 5-pin SC70 package, while the MAX4451 is available in space-saving 8-pin SOT23 and SO packages.
The MAX4450 (single‑channel) and MAX4451 (dual‑channel) are unity‑gain‑stable voltage‑feedback amplifiers that combine high speed with rail‑to‑rail outputs. They operate from a +4.5 V to +11 V single supply or from ±2.25 V to ±5.5 V dual supplies and draw only 6.5 mA per amplifier.
Key specifications include a 210 MHz –3 dB bandwidth, 485 V/µs slew rate, input common‑mode range that extends beyond the negative rail, and low distortion. The devices are offered in ultra‑small SC70 (MAX4450) and space‑saving SOT23/SO (MAX4451) packages, making them suitable for low‑power video, communications and instrumentation applications.
