The LTC321/LTC358/LTC324 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 70 μA) combined with a wide bandwidth (1.2 MHz) and low noise (27 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 mega-ohm source impedances.
The robust design of the LTC321/LTC358/LTC324 family 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 LTC321/LTC358/LTC324 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),
and over the extended temperature range of -40 ℃ to +125 ℃.
