LM4040CIM3-4.1 Description

Short technical summary and product information.

The Texas Instruments LM4040CIM3-4.1 is a precision micropower shunt voltage reference designed for space-critical applications. It features a fixed reverse breakdown voltage of 4.096V with a tight tolerance of ±0.1% at 25°C.

 

This voltage reference boasts a low temperature coefficient of 100ppm/°C maximum and operates efficiently over a wide current range from 60µA to 15mA. It also exhibits low output noise, with a typical value of 35µVrms from 10Hz to 10kHz, and does not require an output capacitor, tolerating capacitive loads.

 

The LM4040CIM3-4.1 is available in a small SOT-23 (DBZ) surface-mount package, making it suitable for compact designs. It supports industrial temperature ranges from -40°C to +85°C and extended ranges up to +125°C.

 

This device is ideal for applications requiring a stable and accurate voltage reference where space and power consumption are critical considerations.
