LM6142 Dual and LM6144 Quad

High Speed/Low Power 17 MHz Rail-to-Rail Input-Output

Operational Amplifiers

General Description

Features

Using patent pending new circuit topologies, the LM6142/44

provides new levels of performance in applications where

low voltage supplies or power limitations previously made

compromise necessary. Operating on supplies of 1.8V to

over 24V, the LM6142/44 is an excellent choice for battery

operated systems, portable instrumentation and others.

At V_S5V. Typ unless noted.

n Rail-to-rail input CMVR −0.25V to 5.25V

n Rail-to-rail output swing 0.005V to 4.995V

n Wide gain-bandwidth: 17 MHz at 50 kHz (typ)

n Slew rate:

Small signal, 5V/µs

The greater than rail-to-rail input voltage range eliminates

concern over exceeding the common-mode voltage range.

The rail-to-rail output swing provides the maximum possible

dynamic range at the output. This is particularly important

when operating on low supply voltages.

Large signal, 30V/µs

n Low supply current 650 µA/Amplifier

n Wide supply range 1.8V to 24V

n CMRR 107 dB

n Gain 108 dB with R_L10k

High gain-bandwidth with 650 µA/Amplifier supply current

opens new battery powered applications where previous

higher power consumption reduced battery life to unaccept-

able levels. The ability to drive large capacitive loads without

oscillating functionally removes this common problem.

n PSRR 87 dB

Applications

n Battery operated instrumentation

n Depth sounders/fish finders

n Barcode scanners

n Wireless communications

n Rail-to-rail in-out instrumentation amps
