LT1461ACS8-4#PBF is a part of the PMIC (Power Management Integrated Circuit) family, specifically the Voltage Reference family. A voltage reference is a device that provides a stable reference voltage, regardless of any other circuit parameters and changes. This is particularly important, because the accuracy needed of a constant reference voltage – the “Y” reference – varies based on the circuit and the application. The key benefit of using a voltage reference is its stability, which allows it to accurately and easily supply the same reference voltage over time and temperature variations. This makes it easier and more efficient when designing circuits where reference voltages are required.

LT1461ACS8-4#PBF is a high accuracy and low temperature drift voltage reference that operates over a wide temperature range. It provides an output voltage of 4.2500 V ± 5 mV over the temperature range of -40 to 85 °C. The reference is designed to operate from a single 5 V power supply, providing an output current of 400 μA. It also features a low output noise and low line and load regulation that make it especially useful in noisy and/or high voltage applications.

The LT1461ACS8-4#PBF is available as a surface mount component and is housed in a small SOIC package, making it ideal for applications with space constraints. Additionally, its high accuracy and wide temperature range make it a perfect choice for applications that require stable references over temperature. In power supply systems, the LT1460CSPBF is a great choice for systems with multiple processors or over wide temperature variations. Other possible applications include video systems, telecom systems, datacom equipment, process automation and instrumentation.

The working principle of the LT1461ACS8-4#PBF is based on a combination of circuits and topologies. It uses an on-chip voltage reference and a precision resistor network to provide an output voltage of 4.2500V±5mV over the component\'s specified temperature range. This on-chip voltage reference is supplied with a bandgap reference and a precision trimming resistor to achieve the desired voltage. The resistor network is composed of low temperature coefficient resistors (TCR) and temperature compensated resistors (TCRs) for maximum stability. The LT1461ACS8-4#PBF also features low line and load regulation, output noise and a low power supply current to ensure the output remains stable and accurate across varying conditions.

To sum it up, the LT1461ACS8-4#PBF is a high accuracy and low temperature drift voltage reference product from the Power Management Integrated Circuit family. It is ideal for applications requiring reference voltages over a wide temperature range, such as power supply systems, video systems, telecom systems, datacom equipment, process automation and instrumentation. The LT1461ACS8-4#PBF operates over a wide temperature range and its output voltage is 4.2500V±5mV. Its working principle is based on an on-chip voltage reference and precision resistor network, which together provide an exceptionally stable output signal.
