製品概要The PM155 provides low input current, high slew rate, and direct interchangeability with LF155 type. This operational amplifier uses a new process which allows fabrication of matched JFET transistors and standard bipolar transistors on the same chip. High accuracy make the PM155 useful in new designs and as replacements for modular and hybrid types. Unlike many designs, nulling the input offset voltage does not degrade common-mode rejection ratio or input offset voltage drift. Low input voltage noise and current noise plus a low 1/f noise corner frequency allow these amplifiers to be used in a variety of low noise, wide-bandwidth applications.
Dynamic specifications for the PM155 include a typical slew rate of 5V/µs, a 2.5MHz gain bandwidth product, and settling time to within ±0.01% of final value in 5.0µs.
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
