LT1461ACS8-5#TRPBF

The LT1461ACS8-5#TRPBF (LT1461) is an adjustable surge-protected micropower reference from Linear Technology Corporation. Featuring an auto-clamping of transient voltages on an adjustment pin for accurate and reliable voltage settings, the LT1461 belongs to the family of Voltage References from Linear Technology and is mostly used in precision precision operational amplifier control loops.

The LT1461 is a precision two-terminal micropower voltage reference with an adjustable voltage output up to 24.75V. It can operate from an input voltage of 4.5V to 42V making it suitable for a wide range of supply voltages. It achieves high accuracy for the output voltage across a wide temperature range, with reference temperatures ranging from -40°C up to 125°C. It features an exceptionally low quiescent current of 2.8µA which makes the device suitable for portable instruments and handheld devices. The device also features an auto-clamping functionality to protect against transient voltages, thereby making it an ideal choice for precision control loops and high-accuracy applications.

The LT1461 operates on a proprietary Micropower References (µP-REF) process that ensures high accuracy and low offset, drift, and temperature coefficient of the output voltage. This is achieved through the integration of high gain and low offset op amps, and high precision resistors. The LT1461\'s operation is based on a standard OPAMP based amplifier and the reference is buffered by a precision op amp across a wide temperature range. The LT1461\'s output voltage is adjustable with the aid of a voltage divider network, and the divider is adjustable via a pin for easy factory calibration. The device is designed for use in precision operational amplifier control loops as it has excellent accuracy across a wide temperature range of up to 125°C.

The LT1461 is ideal for applications in high-accuracy control loops and precision operational amplifier control loops. It is suitable for use in portable instruments, automotive, computing and industrial applications, due to its wide temperature range, low quiescent current, high accuracy and auto-clamping protection against transient voltages. The reference has been designed with a host of features that enable it to be suitable for use in a wide range of applications, making it an ideal choice for industrial, automotive and mobile applications.
