KM4110/KM4120

0.5mA, Low Cost, +2.7V & +5V, 75MHz Rail-to-Rail Amplifiers

Features

General Description

The KM4110 (single) and KM4120 (single with disable)

are low cost, voltage feedback aꢀplifiers. These

aꢀplifiers 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.

ꢀ

505µA supply current

ꢀ

75MHz bandwidth

ꢀ

Power down to I = 33µA (KM4120)

ꢀ

Fully specified at +2.7V and +5V supplies

ꢀ

Output voltage range: 0.07V to 4.86V; V = +5

ꢀ

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

ꢀ

50V/µs slew rate

The KM4110 offers superior dynaꢀic perforꢀance

with a 75MHz sꢀall signal bandwidth and 50V/µs

slew rate. The coꢀbination of low power, high

output current drive, and rail-to-rail perforꢀance

ꢀake the KM4110 well suited for battery-powered

coꢀꢀunication/ coꢀputing systeꢀs.

ꢀ

15ꢀA linear output current

ꢀ

30ꢀA output short circuit current

ꢀ

12nV/√Hz input voltage noise

ꢀ

Directly replaces AD8031 in single

supply applications

ꢀ

Sꢀall package options (SOT23-5 and SOT23-6)

The coꢀbination of low cost and high perforꢀance

ꢀake the KM4110 suitable for high voluꢀe applica-

tions in both consuꢀer and industrial applications

such as wireless phones, scanners, and color copiers.

Applications

ꢀ

Portable/battery-powered applications

A/D buffer

ꢀ

Active filters

ꢀ

Signal conditioning

Portable test instruꢀents

Non-Inverting Freq. Response V = +5V
