LTC8835数据手册Linearin中文资料规格书

描述 Description

The LTC883x family of single-, dual-, and quad- channel operational amplifiers represents a new generation of precision, low-power op-amps. Featuring rail-to-rail input and output (RRIO) swings, low quiescent current (typical 720 µA) combined with a wide bandwidth (9 MHz) and very low noise (12 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, motor phase current sensing, photodiode amplification, barcode scanners 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 LTC883x 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 LTC883x amplifiers are optimized for operation at voltages as low as +2.0 V (± 1.0 V) and up to +5.5 V (± 2.75 V) over the

extended temperature range of -40 ℃ to +125 ℃.



The LTC8835 (single) is available in both SOT23-5L and SC70-5L packages. The LTC8836 (dual) is offered in SOIC-8L and MSOP-8L packages. The quad-channel LTC8838 is offered in both SOIC-14L and TSSOP-14L packages.
