描述 Description

The LTC6001U of single-channel operational amplifiers is specifically designed forgeneral-purpose cost-sensitive systems and applications. Featuring rail-to-rail inputand output (RRIO) swings, and low quiescent current (typical 75 μA) combined with awide bandwidth (1.5 MHz) and very low noise (25 nV/√Hz at 1 kHz) makes this family veryattractive for a variety of battery-powered applications that require a good balancebetween cost and performance, such as audio outputs, consumer electronics, smokedetectors, portable medical devices and white goods. The low input bias currentsupports these amplifiers to be used in applications with mega-ohm source impedances.

The robust design of the LTC6001U amplifiers provides ease-of-use to the circuitdesigner: unity-gain stability with capacitive loads of up to 500 pF, integrated RF/EMIrejection filter, no phase reversal in overdrive conditions, and high electro-staticdischarge (ESD) protection (5-kV HBM). The LTC6001 amplifiers are optimized foroperation at voltages as low as +1.8 V (±0.9 V) and up to +5.5 V (±2.75 V) at thetemperature range of 0 ℃ to 70 ℃, and operation at voltages from +2.0 V (±1.0 V) to +5.5V (±2.75 V) over the extended temperature range of ?40 ℃ to +125 ℃.

The LTC6001U (single) is available in both SOT23-5L and SC70-5L packages.
