LTC1967IMS8#PBF

LTC1967 is a true RMS-to-DC converter that uses an innovative delta-sigma computational technique. The benefits of the device proprietary architecture when compared to conventional log-antilog RMS-to-DC converters are higher linearity and accuracy, bandwidth independent of amplitude and improved temperature behaviour. It operates with single-ended or differential input signals (for EMI/RFI rejection) and supports crest factors upto 4. Common mode input range is rail-to-rail. Differential input range is 1VPEAK, and offers unprecedented linearity. It allows hassle-free system calibration at any input voltage. It is widely used in application such as true RMS digital multimeters and panel meters, true RMS AC + DC measurements etc.

• Linearity error is 0.02% typical
