EVALUATION KIT AVAILABLE MAX9633 Dual 36V Op Amp for 18-Bit SAR ADC Front-End The MAX9633 is a low-noise, low-distortion operational amplifier that is optimized to drive ADCs for use in applications from DC to a few MHz. The MAX9633 features low noise at 1kHz and at 100Hz and low distortion 130dB at 10kHz , making it suitable for industrial, medical, and test applications. The exceptionally fast settling-time and low input offset voltage makes the IC an excellent solution to drive highresolution 12-bit to 18-bit SAR ADCs. The IC operates from a wide supply voltage range up to 36V with only 3.5mA of quiescent current per amplifier. The IC is offered in an 8-pin, 3mm x 3mm TDFN package for operation over the -40NC to +125NC temperature range.
