LTC6655 Pinout

Product Overview

The LTC6655 is a complete family of precision bandgap voltage references, offering exceptional noise and drift performance. This low noise and drift is ideally suited for the high resolution measurements required by instrumentation and test equipment. In addition, the LTC6655 is fully specified over the temperature range of –40°C to 125°C, ensuring its suitability for demanding automotive and industrial applications. Advanced curvature compensation allows this bandgap reference to achieve a drift of less than 2ppm/°C with a predictable temperature characteristic and an output voltage accurate to ±0.025%, reducing or eliminating the need for calibration.

 

The LTC6655 can be powered from as little as 500mV above the output voltage to as much as 13.2V. Superior load regulation with source and sink capability, coupled with exceptional line rejection, ensures consistent performance over a wide range of operating conditions. A shutdown mode is provided for low power applications.

 

This blog will introduce LTC6655 systematically from its features, pinout to its specifications, applications, also including LTC6655 datasheet and so much more.

LTM4622 FAQ

What are the benefits of using the ltc6655?

This presentation will explain the significance of noise in high performance instrumentation and test equipment, and provide an overview of the LTC6655 main features and benefits.

 

What is the temperature range of the ltc6655?

This low noise and drift is ideally suited for the high resolution measurements required by instru - mentation and test equipment. In addition, the LTC6655 is fully specified over the temperature range of 40°C – to 125°C, ensuring its suitability for demanding auto- motive and industrial applications.

 

How much voltage does ltc6655 low dropout reference use?

The LTC6655 low dropout series references can be powered from as little as 500 mV above the output voltage or as much as 13.2 V. Superior load regulation and source and sink capabilities coupled with exceptional line rejection give consistent performance over a wide range of line and load conditions.

 

Is there a shutdown mode for the ltc6655?

A shutdown mode is provided for low power applications. The LTC6655 references are offered in an 8-lead MSOP package and an 8-lead LS8 package. The LS8 is a 5mm × 5mm surface mount hermetic package that pro- vides outstanding stability. All registered trademarks and trademarks are the property of their respective owners.

 

Why is voltage reference needed?

A voltage reference is a precision device specifically designed to maintain a constant output voltage, even as parameters such as ambient temperature or supply voltage change. The precision of a voltage reference enables its use in several differ- ent types of applications beyond a data converter.
