LMC6681 Single/LMC6682 Dual/LMC6684 Quad Low Voltage, Rail-To-Rail Input and Output CMOS
Amplifier with Powerdown
May 1995
LMC6681 Single/LMC6682 Dual/LMC6684 Quad
Low Voltage, Rail-To-Rail Input and Output CMOS
Amplifier with Powerdown
General Description
The LMC6681/2/4 is a high performance operational ampli-
fier which can operate over a wide range of supply voltages,
with guaranteed specifications at 1.8V, 2.2V, 3V, 5V, and
10V.
The LMC6681/2/4 provides an input common-mode voltage
range that exceeds both supplies. The rail-to-rail output
swing of the amplifier assures maximum dynamic signal
range. This rail-to-rail performance of the amplifier, com-
bined with its high open-loop voltage gain makes it unique
among CMOS rail-to-rail amplifiers. The LMC6681/2/4 is an
excellent choice for circuits where the common-mode volt-
age range is a concern.
The LMC6681/2/4 has a powerdown mode which can be
controlled externally. In this powerdown mode, the supply
current decreases from 700 碌A(chǔ) per amplifier to less than 1
碌A(chǔ) per amplifier. The LMC6684 has two powerdown options.
Each of the powerdown pins disables two amplifiers.
The LMC6681/2/4 has been designed specifically to improve
system performance in low voltage applications. The ampli-
fier鈥檚 80 fA input current, 0.5 mV offset voltage, and 82 dB
CMRR maintain accuracy in battery-powered systems.
