LT1999HMS8-20 Description

Short technical summary and product information.

The LT1999HMS8-20 is a high-speed precision current sense amplifier from Linear Technology, designed to monitor bidirectional currents across a broad common mode voltage range of -5V to 80V. This amplifier is available in three distinct gain options: 10V/V, 20V/V, and 50V/V, providing flexibility for various current sensing applications.

 

Featuring a 2MHz bandwidth and high gain accuracy of 0.5% maximum, the LT1999HMS8-20 is suitable for applications such as H-Bridge motor controls, switching power supplies, solenoid current monitoring, and battery charge current management. It operates from an independent 5V supply and includes a low power shutdown mode, consuming less than 10µA.

 

The device is available in an 8-lead MSOP or an 8-lead SO (Narrow) package, both suitable for surface mount applications. It also offers high tolerance to electrostatic discharge, with 4kV HBM and 1kV CDM ratings, ensuring robustness in demanding environments.
