The KM4210 uses only 505µA of supply current per amplifer, and is designed to operate on +2.7V, +5V, or ±2.5V supplies. The input voltage range extends 300mV below the negative rail and 1.2V below the positive rail. The KM4210 offers high bipolar performance at a low CMOS price. The KM4210 offers superior dynamic performance with a 75MHz small signal bandwidth and 50V/µs slew rate. The combination of low power, high bandwidth, and rail-to-rail performance make the KM4210 well suited for battery-powered communication/computing systems. The KM4110 (single) and KM4120 (single with disable) are also available. © 2001 Fairchild Semiconductor International Patents Pending P e r m i l i a n Container Rail Reel y r Units MHz nV/√Hz V/µs µA Eval Bd* KEB010 KEB010 Ordering Information Part No. Package KM4210IM8 MSOP-8 KM4210IM8TR3 MSOP-8 Pack Qty 50 4000 Temperature range for all parts: -40°C to +85°C. * Evaluation boards are available to aid in the evaluation of these products.
