MAX9000MAX9005 19-0499 Rev 1 7/98 Low-Power, High-Speed, Single-Supply Op Amp + Comparator + Reference ICs General Description Features The MAX9000 family features the combination of a high- Op Amp + Comparator + Reference in speed operational amplifier, a 185ns comparator, and a Space-Saving MAX Package precision 1.230V reference. These devices operate from a +2.5V to +5.5V Single-Supply Voltage Range single +2.5V to +5.5V supply and draw less than 500A of quiescent current. The MAX9001/MAX9004 feature a shut- 340A Supply Current (MAX9002/MAX9005) down mode that reduces supply current to 2A and puts Unity-Gain Stable (GBW = 1.25MHz) and the outputs into a high-impedance state, making them Decompensated (A 10V/V, GBW = 8MHz) Options V ideal for portable and battery-powered applications. Op-Amp/Comparator Outputs Swing Rail-to-Rail The amplifiers in the MAX9000/MAX9001/MAX9002 are unity-gain stable with a 1.25MHz gain-bandwidth product, Ground-Sensing Inputs for Both Op Amp and while the amplifiers in the MAX9003/MAX9004/MAX9005 Comparator are stable for closed-loop gains of +10V/V or greater with Op Amp Stable with Capacitive Loads up to 250pF an 8MHz gain-bandwidth product. The input common- Internal 2mV Comparator Hysteresis mode voltage extends from 150mV below the negative supply to within 1.2V of the positive supply for the amplifi- Fast 185ns Propagation-Delay Comparator er, and to within 1.1V for the comparator. The amplifier and No Phase Reversal for Overdriven Inputs comparator outputs can swing Rail-to-Rail and deliver up (Both Op Amp and Comparator) to 2.5mA and 4.0mA, respectively, to an external load while maintaining excellent DC accuracy. The unique Internal 1.230V Precision Reference (MAX9000/ design of the comparator output stage substantially MAX9001/MAX9003/MAX9004) reduces switching current during output transitions, virtually 1% Initial Accuracy eliminating power-supply glitches. Low 8ppm/C Temperature Drift The comparators 2mV of built-in hysteresis provides Sink or Source up to 1mA noise immunity and prevents oscillations even with a Stable for Capacitive Loads up to 100nF slow-moving input signal. The MAX9000/MAX9001/ MAX9003/MAX9004 have an internal 1.230V 1% preci- sion reference with a low 8ppm/C temperature coeffi- Ordering Information cient that can sink or source up to 1mA. The amplifier and PART TEMP. RANGE PIN-PACKAGE reference are stable with capacitive loads up to 250pF MAX9000EUA -40C to +85C 8 MAX and 100nF, respectively. The comparators inverting input MAX9000ESA -40C to +85C 8 SO is internally connected to the reference output in the MAX9000/MAX9003.
