LT6654AIS6-3#TRMPBF Application Field

The LT6654AIS6-3#TRMPBF reference is a single, high-precision, low-noise voltage reference designed for precision analog to digital converters and data acquisition systems. This low-power device features a 7.8mV fixed output voltage and a maximum power dissipation of 18mW. The device is fully specified over the ambient temperature range of -35°C to +85°C. It is ideal for use in low-noise, low-voltage and high-accuracy applications.

The LT6654AIS6-3#TRMPBF is designed to provide a stable output voltage regardless of load, supply voltage and temperature variation. The output voltage is trimmed and specified to an accuracy of +/- 0.05%. The device is also immune to power supply noise and therefore provides very stable operation when exposed to noisy or fluctuating environments. The device is available in a 2mm x 1.65mm package, making it suitable for professional applications where space is at a premium.

The LT6654AIS6-3#TRMPBF reference is designed for use in a wide range of applications, from low voltage to high voltage, from high accuracy to low power. The device can be used for test and measurement equipment, medical instrumentation, audio and video equipment, telecommunications systems and automobiles. It is also suitable for industrial and consumer electronics, where its low noise, low power and high accuracy make it ideal.

LT6654AIS6-3#TRMPBF Working Principle

The LT6654AIS6-3#TRMPBF reference uses a band-gap voltage reference to provide a precise, low-noise output voltage. The band-gap reference circuit uses a combination of resistors, capacitors and transistors to achieve a constant voltage output by exploiting the intrinsic properties of the silicon material. The device consists of two transistor amplifiers biased by a band-gap reference circuit. The output voltage is determined by the ratio of the two transistors\' currents. This ratio is maintained by the band-gap reference circuit, which is designed to precisely maintain a constant voltage. The reference output is then buffered and amplified to provide the desired voltage.

The output voltage of the LT6654AIS6-3#TRMPBF reference is trimmed and specified to an accuracy of +/- 0.05%. The device features fast start-up and high accuracy at load currents from 10µA to 10mA. The output impedance is very low (<2kΩ) and it is immune to power supply noise. The dropout voltage at full load is typically less than 6mV, making it ideal for low-dropout applications. The device is also rated for a temperature operating range of -40°C to +125°C, making it suitable for a wide range of environments.
