EVALUATION KIT AVAILABLE MAX9632 36V, Precision, Low-Noise, Wide-Band Amplifier General Description Benefits and Features The MAX9632 is a low-noise, precision, wide-band S DC and AC Performance Ideal for High-Resolution operational amplifier that can operate in a very wide ADC Driver Applications +4.5V to +36V supply voltage range. The IC operates in 55MHz Gain-Bandwidth dual (18V) mode. 600ns Settling Time to 16-Bit Accuracy THD of -128dB at 10kHz The exceptionally fast settling time and low distortion Low Input Offset Voltage 125V (max) make the IC an excellent solution for precision acquisi- 0.94nV/Hz Ultra-Low Input Voltage Noise tion systems. The rail-to-rail output swing maximizes the Low Input Offset Temperature Drift 0.5V/C dynamic range when driving high-resolution 24-bit (max) ADCs even with low supply voltages. Unity-Gain Stable The IC achieves 55MHz of gain-bandwidth product and S Wide Supply for High-Voltage Front-Ends ultra-low 0.94nV/Hz input voltage noise with only 3.9mA +4.5V to +36V Supply Range of quiescent current. S Improved Reliability with ESD Protection M The IC is offered in 8-pin SO, MAX , and TDFN pack- 8kV HBM and 1kV CDM ESD ages and is rated for operation over the -40NC to +125NC temperature range.
