The LTC882x family of single-, dual-, and quad- channel amplifiers provides input offsetvoltage correction for low offset (maximum 350 μV) and drift (typically 0.8 μV/℃)through the use of proprietary techniques. Featuring rail-to-rail input and output swings,and low quiescent current (typical 15 µA at 5V supply) combined with a wide bandwidthof 500 kHz and very low noise (6 μVP-P at 0.1 to 10 Hz) makes this family very attractivefor a variety of battery-powered applications such as wearables, tablets, and portablemedical devices. The low input bias current supports these amplifiers to be used inapplications with mega-ohm source impedances.

The robust design of the LTC882x operational amplifiers provides ease-of-use to thecircuit designer: integrated RF/EMI rejection filter, no phase reversal in overdriveconditions, and high electro-static discharge (ESD) protection (5-kV HBM and 2-kV CDM).The LTC882x 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).

The LTC8825/8827 (single) is available in both SOT23-5L and SC70-5L packages. TheLTC8826 (dual) is offered in DFN-8L, SOIC-8L and MSOP-8L packages. The quad-channel LTC8828 is offered in both SOIC-14L and TSSOP-14L packages. All of the devicesare specified over the extended temperature range of −40 ℃ to +125 ℃.
