LT1634AIS8-4.096#PBF Voltage Reference

The LT1634AIS8-4.096#PBF is a dual channel, low-dropout (LDO) voltage reference designed by Linear Technology. It features eight adjustable voltage outputs that can be set between 0.7V to 4.096V using external resistors. This makes it suitable for a wide range of different applications, from powering a variety of digital logic circuits to providing adjustable voltages for memory, microprocessor, and other sensitive analog circuits.

The LT1634AIS8-4.096#PBF contains an output buffer and a voltage sensing circuitry that allows it to regulate its output voltage within a very tight tolerance—typically ±50mV in the range of 0.7V to 4.096V. It also includes a Monitoring On/Off control line that can be used to control the device’s output. The LT1634AIS8-4.096#PBF also features a low-noise, high-stability (+/- 0.8mV/C) reference voltage output (2.5V) that can be used to accurately set the voltage of analog circuits. It’s also protected against short-circuit and reverse-polarity faults, making it suitable for many industrial, medical, and military applications.

Working Principle of LT1634AIS8-4.096#PBF

The LT1634AIS8-4.096#PBF works by using a voltage divider to adjust the output voltage, as shown in the diagram below. Two external resistors, R1 and R2, are connected to the reference pin (REF) and to the Adj pin. The voltage at the Adj pin is determined by the ratio of the resistors, which is then used to control the output voltage on the OUT pin. Any change in the voltage at the Adj pin will cause the output voltage to track that change, allowing the LT1634AIS8-4.096#PBF to regulate the output voltage over a wide range of input voltages.

The value of the resistors can be calculated using the following equation:

R1/R2 = (Vout - 0.7V) / 0.7V

where:
Vout is the desired output voltage in volts
R1 and R2 are the values of the resistors in Ohm\'s.

The LT1634AIS8-4.096#PBF also features a low-bias current source, which makes it suitable for battery-powered applications or low-power applications. This allows the voltage reference to draw nearly no current when the output voltage is set to 0.7V, allowing the LT1634AIS8-4.096#PBF to be used in devices that require very low power consumption.

The LT1634AIS8-4.096#PBF also includes native temperature compensation capabilities and a variety of fault protection features, such as short-circuit protection, reverse-polarity protection, and over-temperature protection, making it suitable for use in many different environments, from harsh industrial settings to sensitive laboratory applications.
