LTC1968 - 精准宽带宽、RMS 至 DC 转换器

The LTC1968 operates with single-ended or differential input signals and accurately supports crest factors up to 4. Common mode input range is rail-to-rail. Differential input range is 1VPEAK, and offers unprecedented linearity. The LTC1968 allows hassle-free system calibration at any input voltage.

The LTC1968 has a rail-to-rail output with a separate output reference pin providing flexible level shifting; it operates on a single power supply from 4.5V to 5.5V. A low power shutdown mode reduces supply current to 0.1µA.

The LTC1968 is packaged in the space-saving MSOP package, which is ideal for portable applications.
