Ultra-Small, Low-Cost, 210MHz, Single-Supply Op Amps with Rail-to-Rail Outputs

Industry's First Video Amps in Ultra Small SC70 Package

Product Details

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 a space-saving 8-pin SOT23 and SO packages.

Description

The MAX4450 evaluation kit (EV kit) demonstrates the capability of the high-speed MAX4450 operational amplifier configured in a 3-pole, lowpass Sallen-Key filter which provides a Butterworth response with a bandwidth of -3dB at 5.25MHz. This circuit can be used for video anti-aliasing and reconstruction filtering. The circuit is designed to drive a 75Ω termination, common in video applications, with an overall gain of 1. The MAX4450 EV kit board operates from a ±2.25V to ±5.5V dual-voltage supply or a +4.5V to +11V single-voltage supply. The MAX4450 EV kit is a fully assembled and tested surface-mount board.
