LT1790BCS6-2.5#TRMPBF

Product Overview

The LT1790BCS6-2.5#TRMPBF from Analog Devices Inc. is a fixed series voltage reference IC that provides a 2.5 V output with ±0.1% tolerance and a 25 ppm/°C temperature coefficient. It operates from an input voltage range of 3 V to 18 V and delivers 5 mA output current. The device uses a surface-mount TSOT-23-6 package and draws 80 µA supply current. Noise values include 32 µVp-p over 0.1 Hz to 10 Hz and 48 µVrms over 10 Hz to 10 kHz, supporting circuits that need a stable voltage reference for measurement, conversion, or control functions.

Key Features

• Fixed 2.5 V series voltage reference output
• ±0.1% output tolerance
• 25 ppm/°C temperature coefficient
• Input voltage range of 3 V to 18 V
• 5 mA output current
• 80 µA supply current
• Noise of 32 µVp-p from 0.1 Hz to 10 Hz and 48 µVrms from 10 Hz to 10 kHz
• Operating temperature range of 0 °C to 70 °C (TA)
• Surface-mount TSOT-23-6 package

Applications

• Providing a fixed reference voltage for analog-to-digital conversion
• Establishing a reference voltage for sensor signal conditioning
• Supporting measurement circuits that are sensitive to reference noise
• Providing a reference point for control or calibration circuitry

Design & Procurement Notes

Design considerations should account for the 3 V to 18 V input range and the 5 mA output current when interfacing to loads. The fixed 2.5 V output, ±0.1% tolerance, and 25 ppm/°C temperature coefficient determine reference accuracy across the 0 °C to 70 °C ambient range. Noise values of 32 µVp-p over 0.1 Hz to 10 Hz and 48 µVrms over 10 Hz to 10 kHz should be considered for sensitive analog measurement or converter reference paths. The 80 µA supply current and TSOT-23-6 surface-mount package affect board layout and power budget.
