LT1790BCS6-2.048#TRMPBF

Product Overview

The LT1790BCS6-2.048#TRMPBF from Analog Devices Inc. is a fixed-output series voltage reference in a TSOT-23-6 surface-mount package. It provides a 2.048V reference with ±0.1% tolerance and a 25ppm/°C temperature coefficient. The device operates from an input range of 2.8V to 18V and provides output current of 5 mA while drawing 75µA supply current. Its noise specifications are 22µVp-p from 0.1Hz to 10Hz and 41µVrms from 10Hz to 10kHz, supporting a fixed reference point for analog signal chains and compact board layouts.

Key Features

• Fixed 2.048V series voltage reference output

• Temperature coefficient of 25ppm/°C
• Input voltage range from 2.8V to 18V
• Output current of 5 mA
• Supply current of 75µA
• Noise of 22µVp-p from 0.1Hz to 10Hz and 41µVrms from 10Hz to 10kHz
• TSOT-23-6 surface-mount package

Applications

• Analog-to-digital converter reference input in measurement modules
• Digital-to-analog converter reference node in control signal generation
• Sensor biasing or excitation circuits requiring a fixed voltage
• Reference input for power management control loops

Design & Procurement Notes

When selecting this part for a design, verify that the available input voltage remains within 2.8V to 18V and that the load current does not exceed 5 mA. The fixed 2.048V output and ±0.1% tolerance define the nominal reference level for analog nodes, while the 25ppm/°C coefficient and noise figures should be considered in precision signal chains. The TSOT-23-6 surface-mount package supports compact layouts, but the 0°C to 70°C operating temperature range should be checked against the intended environment.
