KM4170, KM4270, KM4470 Low Cost, +2.7V & +5V, Rail-to-Rail I/O Amplifiers Features at 2.7V • 136µA supply current per amplifier • 4.9MHz bandwidth • Output swings to within 20mV of either rail • Input voltage range exceeds the rail by >250mV • 5.3V/µs slew rate • 16mA output current • input voltage noise • KM4170: directly replaces OPA340, OPA343, and TLV2461 in single supply applications and available in SC70-5 and SOT23-5 package options • KM4270 directly replaces MAX4126, OPA2340, LMV822 and TLV2462 in single supply applications and available in SOIC-8 and MSOP-8 package options • KM4470 directly replaces MAX4129, OPA4340, LMV824 and TLV2464 in single supply applications and available in TSSOP-14 package option • Portable/battery-powered applications • PCMCIA, USB • Mobile communications, cellular phones, pagers • Notebooks and PDA’s • Sensor Interface • A/D buffer • Active filters • Signal conditioning • Portable test instruments The KM4170 single , KM4270 dual , and KM4470 quad are ultra-low cost, low power, voltage feedback amplifiers. At 5V, the KM4X70 family uses only 160µA of supply current per amplifier and are designed to operate from a supply range of 2.5V to 5.5V to The input voltage range exceeds the negative and positive rails. The KM4X70 family of amplifiers offer high bipolar performance at a low CMOS prices. They offer superior dynamic performance with 4.9MHz small signal bandwidths and 5.3V/µs slew rates. The combination of low power, high bandwidth, and rail-to-rail performance make the KM4X70 amplifiers well suited for battery-powered communication/ computing systems.
