LTC1966CMS8#PBF

Product Overview

The LTC1966CMS8#PBF from Analog Devices Inc. is a surface-mount RMS-to-DC converter packaged in an 8-MSOP package. The device operates from a 2.7 V to 5.5 V supply and draws 155 µA supply current. Its 8-TSSOP/8-MSOP case, 0.118 in (3.00 mm) wide, supports compact power-management and signal-conditioning layouts. The part number identifies an 8-MSOP variant, and the mounting type is surface mount.

Key Features

• RMS-to-DC conversion function for power-management and signal-conditioning circuitry.
• 2.7 V to 5.5 V supply range.
• 155 µA supply current.
• Surface-mount 8-MSOP package.
• 8-TSSOP, 8-MSOP case with 0.118 in (3.00 mm) width.

Applications

• RMS measurement front ends for voltage or current signals.
• Power-monitoring circuits that convert an RMS quantity to a DC output.
• Signal-conditioning paths where an RMS value must be represented as a DC level.
• Power-management subsystems requiring RMS-to-DC conversion.

Design & Procurement Notes

Designers should verify that the 2.7 V to 5.5 V supply and 155 µA current fit the system power budget. The 155 µA supply current should be included in power calculations. The 8-MSOP package is a surface-mount form factor, so pad geometry should be checked. The 8-MSOP package width of 0.118 in (3.00 mm) should be checked against PCB pad and courtyard constraints. The 2.7 V to 5.5 V supply range should be matched to the available regulator output. Because the device is an RMS-to-DC converter, external input and output choices should be evaluated from the application schematic rather than inferred from the package data.
