LT6003/LT6004/LT6005
1.6V, 1µA Precision
Rail-to-Rail Input and
Output Op Amps
FEATURES
DESCRIPTION
The LT®6003/LT6004/LT6005 are single/dual/quad op
amps designed to maximize battery life and performance
forportableapplications.Theseamplifiersoperateonsup-
plies as low as 1.6V and are fully specified and guaranteed
over temperature on 1.8V, 5V and 8V supplies while only
drawing 1µA maximum quiescent current.
■
Wide Supply Range: 1.6V to 16V
■
Low Supply Current: 1µA/Amplifier Max
■
Low Input Bias Current: 90pA Max
■
Low Input Offset Voltage: 500µV Max
■
Low Input Offset Voltage Drift: 1µV/°C
■
CMRR: 100dB
PSRR: 95dB
■
The ultralow supply current and low operating voltage are
combined with excellent amplifier specifications; input
offset voltage of 500µV maximum with a typical drift of
only 1µV/°C, input bias current of 90pA maximum, open
loop gain of 100,000 and the ability to drive 500pF capaci-
tive loads, making the LT6003/LT6004/LT6005 amplifiers
ideal when excellent performance is required in battery
powered applications.
