The LTC887x family of single-, dual-, and quad- channel amplifiers features a maximized ratio of gain bandwidth (GBW) to supply current and is ideal 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 and white goods. Featuring rail-to-rail input and output swings, a wide bandwidth of 20 MHz combined with low supply current (typical 1.12 mA at 5 V supply per amplifier) and low noise, the LTC887x family is an excellent choice for precision, low-current, low-voltage, battery-powered applications. The low input bias current supports these amplifiers to be used in applications with mega-ohm source impedances.
The robust design of the LTC887x amplifiers provides ease-of-use to the circuit designer:
integrated RF/EMI rejection filter, no phase reversal in overdrive conditions, and high electro- static discharge (ESD) protection (3 kV HBM). The LTC887x 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 LTC8875 (single) is available in both SOT23-5L and SOIC-8L packages. The LTC8876 (dual) is offered in SOIC-8L and MSOP-8L packages. The quad-channel LTC8878 is offered in both
SOIC-14L and TSSOP-14L packages.
