KM4111/KM4121

0.2mA, Low Cost, +2.7V & +5V, 35MHz Rail-to-Rail Amplifiers

Features

General Description

The KM4111 (single) and KM4121 (single with disable)

are ultra-low power, low cost, voltage feedback

aꢀplifiers. These aꢀplifiers use only 208µA of supply

current and are designed to operate on +2.7V, +5V,

or 2.5V supplies. The input voltage range eꢁtends

300ꢀV below the negative rail and 1.2V below the

positive rail.

ꢀ

208µA supply current

ꢀ

35MHz bandwidth

ꢀ

Power down to I = 35µA (KM4121)

ꢀ

Fully specified at +2.7V and +5V supplies

Output voltage range: 0.08V to 4.88V; V = +5

Input voltage range: -0.3V to +3.8V; V = +5

27V/µs slew rate

8.5ꢀA linear output current

13ꢀA short circuit output current

The KM4111 offers high bipolar perforꢀance at a

low CMOS price. The KM4111 offers superior dynaꢀic

perforꢀance with a 35MHz sꢀall signal bandwidth

and 27V/µs slew rate. The coꢀbination of lowpower,

high bandwidth, and rail-to-rail perforꢀance ꢀake

the KM4111 well suited for battery-powered coꢀꢀu-

nication/coꢀputing systeꢀs.

ꢀ

21nV/√Hz input voltage noise

Directly replaces MAX4281
