MAX4435:Single-Supply, 150MHz, 16-Bit Accurate, Ultra-Low Distortion Op Amps

The MAX4434/MAX4435 single and MAX4436/MAX4437 dual operational amplifiers feature wide bandwidth, 16-bit settling time in 23ns, and low-noise/low-distortion operation. The MAX4434/MAX4436 are compensated for unity-gain stability and have a small-signal -3dB bandwidth of 150MHz. The MAX4435/MAX4437 are compensated for closed-loop gains of +5 or greater and have a small-signal, -3dB bandwidth of 150MHz. The MAX4434–MAX4437 op amps require only 15mA of supply current per amplifier while achieving 115dB open-loop gain. Voltage noise density is a low 2.2nV/ and provides 97dB 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 and a high-current output drive up to 65mA. Using a voltage feedback architecture, the MAX4434–MAX4437 meet the requirements of many applications that previously depended on current feedback amplifiers. The MAX4434/MAX4435 are available in space-saving 5-pin SOT23 packages and the MAX4436/MAX4437 are available in 8-pin µMAX® packages.
