19-0499; Rev 1; 7/98 Low-Power, High-Speed, Single-SupplyOp Amp + Comparator + Reference ICsMAX9000–MAX9005General DescriptionFeatures The MAX9000 family features the combination of a high- ♦ Op Amp + Comparator + Reference in speed operational amplifier, a 185ns comparator, and a Space-Saving µMAX Package precision 1.230V reference. These devices operate from a ♦ single +2.5V to +5.5V supply and draw less than 500µA of +2.5V to +5.5V Single-Supply Voltage Range quiescent current. The MAX9001/MAX9004 feature a shut- ♦ 340µA Supply Current (MAX9002/MAX9005) down mode that reduces supply current to 2µA and puts ♦ Unity-Gain Stable (GBW = 1.25MHz) and the outputs into a high-impedance state, making them Decompensated (A ideal for portable and battery-powered applications. V ≥ 10V/V, GBW = 8MHz) Options ♦ The amplifiers in the MAX9000/MAX9001/MAX9002 are Op-Amp/Comparator Outputs Swing Rail-to-Rail 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- mode voltage extends from 150mV below the negative ♦ Internal ±2mV Comparator Hysteresis 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 comparator outputs can swing Rail-to-Rail® and deliver up ♦ No Phase Reversal for Overdriven Inputs to ±2.5mA and ±4.0mA, respectively, to an external load (Both Op Amp and Comparator) 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 comparator’s ±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 reference are stable with capacitive loads up to 250pF PARTTEMP. RANGEPIN-PACKAGE and 100nF, respectively.
