MAX4432:Dual-Supply, 180MHz, 16-Bit Accurate, Ultra-Low-Distortion Op Amps

The MAX4430/MAX4431 single and MAX4432/MAX4433 dual operational amplifiers feature wide bandwidth, 16-bit settling times in 37ns, and low-noise/low-distortion operation. The MAX4430/MAX4432 are compensated for unity gain stability and have a small signal -3dB bandwidth of 180MHz. The MAX4431/MAX4433 are compensated for closed-loop gains of +2 or greater and have a small-signal -3dB bandwidth of 215MHz. The MAX4430–MAX4433 op amps require only 11mA of supply current per amplifier while achieving 125dB open-loop gain. Voltage noise density is a low 2.8nV/√Hz, and provides 100dB spurious-free dynamic range (SFDR) at 1MHz. These characteristics make these op amps ideal for driving modern high-speed 14- and 16-bit analog-to-digital converters (ADCs). These high-speed op amps feature wide output voltage swings capable of driving ADCs with ≥ 4V input dynamic range and a high current output drive up to 60mA. Using a voltage feedback architecture, the MAX4430–MAX4433 meet the requirements of many applications that previously depended on current feedback amplifiers. The MAX4430/MAX4431 are available in a space-saving 5-pin SOT23 package, and the MAX4432/MAX4433 are available in an 8-pin µMAX® package.
