描述
The LTC600x family of single-, dual-, and quad- channel operational
amplifiers is specifically designed for general-purpose cost-sensitive
systems and applications.Featuring rail-to-rail input and output (RRIO)
swings, and low quiescent current
(typical 75 µA) combined
with a wide bandwidth (1.5 MHz) and very low noise (25 nV/√Hz at
1 kHz) makes this family very attractive for a variety of
battery-powered applications that require a good balance between cost
and performance, such as audio outputs,consumer electronics, smoke
detectors, portable medical devices and white goods. The low input bias
current supports these amplifiers to be used in applications with
megaohm source impedances.
The robust design of the LTC600x
amplifiers provides ease-of-use to the circuit designer: unity-gain
stability with capacitive loads of up to 500 pF, integrated
RF/EMI rejection filter, no phase reversal in overdrive conditions, and
high electro-static
discharge (ESD) protection (5-kV HBM). The
LTC600x amplifiers are optimized for operation at voltages as low as
+1.8 V (± 0.9 V) and up to +5.5 V (± 2.75 V) at
the temperature range of 0 ℃ to 70 ℃, and operation at voltages from
+2.0 V (± 1.0 V) to +5.5 V (± 2.75 V) over the
extended temperature range of -40 ℃ to +125 ℃.
The LTC6001
(single) is available in both SOT23-5L and SC70-5L packages. The
LTC6002 (dual) is offered in DFN2x2-8L, SOIC-8L and MSOP-8L packages.
The quad-channel LTC6004 is offered in QFN-16L, SOIC-14L and TSSOP-14L
packages.
