LM4040CIM3X-8.2/NOPB

A voltage reference is a device that provides a known constant voltage output, regardless of the power supply, temperature or loading on the output. Though these devices come in different shapes and sizes, the voltage reference normally provides a much more accurate reference than the available power supply reference. The voltage reference is a crucial element in the circuit, making it possible to process signals with both reasonable accuracy and swings that are close to the supply voltages.

The LM4040CIM3x-8.2/NOPB from Texas Instruments (TI) is a low-dropout series voltage reference that provides a guaranteed 8.2V voltage reference output. This series voltage reference comes in a 5-pin module and is designed for use in a wide range of applications such as digital-to-analog converters (DACs) and analog-to-digital converters (ADCs). In addition, this voltage reference is also suitable for voltage level shifters, rail-to-rail circuits, temperature sensors, and voltage controlled oscillators (VCOs).

Detailed Specifications

The LM4040CIM3X-8.2/NOPB is a single-channel voltage reference, offering a guaranteed 8.2V output and a 0.01% accuracy over its entire range of operation. It is designed with a droop rate of 0.5mV/mA, and requires a current of 0.75mA at full temperature range in order to maintain its accuracy. This droop rate makes it ideal for applications which require a constant output over varying load conditions, such as DACs.

Furthermore, this voltage reference has an operating temperature range from -40°C to 125°C and is offered in the tiny 8-pin LLP package. It also features a very low output impedance and fast transconductance, making excellent for high-precision, low-noise and low-power circuits. Other features include an ESD rating of 3kV, very low voltage noise of 3µV (typical) and excellent PSRR characteristics, which allows for greater protection from line noise.

Benefits & Advantages

The LM4040CIM3X-8.2/NOPB offers some important benefits and advantages. Because it contains an extremely high accuracy voltage output and fast droop rate, it allows for excellent accuracy over varying load conditions, making it ideal for precision applications. In addition, the low voltage noise allows for very good low-noise performance in low-power applications. Furthermore, the ESD rating of 3kV offers excellent protection from electrostatic discharge, while the excellent PSRR characteristics offer greater protection from line noise.
