LT1999CMS8-20 Description

Short technical summary and product information.

The LT1999CMS8-20 is a high-speed precision current sense amplifier designed by LT for monitoring bidirectional currents across a wide common mode range. It is available in three gain options: 10V/V, 20V/V, and 50V/V, with a maximum gain accuracy of 0.5%.

 

This amplifier features a wide input common mode voltage range of -5V to 80V and an AC CMRR greater than 80dB at 100kHz. It has a -3dB bandwidth of 2MHz, making it suitable for applications such as H-Bridge motor controls, switching power supplies, and solenoid current monitoring.

 

The LT1999 operates from an independent 5V supply and draws a typical current of 1.55mA. It includes a low power shutdown mode that consumes less than 10µA. The device is available in an 8-lead SOP or an 8-lead MSOP package, with an option for an FMEA-engineered pinout.

 

Environmental specifications include an operating temperature range of -55°C to 150°C. The component also offers robust ESD protection, with 4kV HBM tolerance and 1kV CDM tolerance.
