The LTC6655CHMS8-2.048#PBF is an ultra low noise, high precision, low dropout voltage reference. This device has an output voltage of 2.048 Volts, a very high output noise of 25 nanovolts, a maximum temperature coefficient of 25ppm/°C and a maximum reference voltage line regulation of 0.02%/V. It is a very useful device in applications where an accurate and ultra low noise reference voltage is required.

As a PMIC (Power Management IC) voltage reference, the LTC6655CHMS8-2.048#PBF can be used in a wide range of applications, including for low voltage and high speed signal processing, precision data acquisition and analog-to-digital conversion, power management, and sensor interface circuits. For example, when used in data acquisition and analog-to-digital conversion applications, its high accuracy, low drift and low noise properties ensure that signals are accurately and reliably converted. Additionally, its low dropout voltage makes it a suitable choice for power management circuits as it ensures that the device is able to operate efficiently under tight voltage constraints.

The device is composed of a linear-regulating NiCd matched pair of transistors, with a matched, temperature-compensated current source and sink, as well as a bandgap output. This combination provides highly accurate output voltage and temperature stability, with a zero-temperature coefficient output at room temperature and exceptionally low noise - the device’s output noise is only 25 nanovolts peak-to-peak. The linear regulator is also capable of outputting a very small dropout voltage (0.7V typical) which allows operation at very low input voltages with minimal sacrifice in precision and stability.

The LTC6655CHMS8-2.048#PBF is a highly reliable device, with a maximum enable/disable turn-on time of only 1µs, and a shutdown current of only 500µA. The device is also extremely small - it is a 6-Pin SOT-23 package which measures just 1.4mm x 1.1mm, making it well-suited for space-constrained applications.

In summary, the LTC6655CHMS8-2.048#PBF is a highly reliable, high precision, low noise voltage reference which can be used in low voltage and high speed signal processing, precision data acquisition and analog-to-digital conversion, power management, and sensor interface circuits. Its combination of low noise and low dropout voltage ensures that it can operate efficiently even under tight voltage constraints, while its small size makes it an ideal choice for use in space-constrained applications.
