LT1034IS8-1.2#TRPBF

Voltage Reference Overview

The LT1034IS8-1.2#TRPBF is a micropower dual voltage reference manufactured by Analog Devices Inc., housed in an 8-pin SOIC surface-mount package. It integrates two precision shunt references within a single component: a primary low-voltage output of 1.225 V and an auxiliary high-voltage output of 7 V. The device operates with a maximum input voltage of 15 V and supports a maximum shunt current of 20 mA, requiring a minimum operating current of 2 mA for regulation. It features an initial accuracy of 1% and a temperature coefficient of 40 ppm/°C. The unit is rated for industrial temperatures ranging from 0°C to +70°C.

Voltage Reference Feature Summary

• Dual-output architecture providing both a 1.225 V primary reference and a 7 V auxiliary reference
• Micropower design optimized for battery-powered applications
• High stability with low temperature coefficient characteristics

Voltage Reference Applications

• Battery-powered instrumentation systems
• Portable measurement devices
• Data acquisition systems requiring multiple reference voltages

Voltage Reference Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing components. Confirm that the IS8 grade meets the required 0°C to +70°C operating temperature range for your application environment. Ensure compatibility with standard SOIC-8 footprints during PCB layout. Cross-reference datasheet specifications against legacy Linear Technology documentation if applicable.

Voltage Reference Selection Notes

Select this component when a compact solution requires two distinct reference voltages without consuming separate IC footprints. The 1.225 V output serves as a standard bandgap reference, while the 7 V auxiliary output can bias other circuit stages. Consider the 40 ppm/°C drift rate against stricter requirements where lower coefficients are necessary.

Voltage Reference Part Context

This part belongs to the LT1034 series of micropower dual references. It shares functional similarities with the LT1034CS8 variant but differs in performance grades and operating temperature ranges. The series is designed to replace discrete resistor divider networks or single-channel references in space-constrained designs.

Voltage Reference FAQ

What is the purpose of the auxiliary 7V output?

The 7V output provides a secondary reference voltage suitable for powering or biasing additional analog circuitry, eliminating the need for external resistive dividers.

Does the LT1034IS8-1.2#TRPBF include a shutdown feature?

No, the LT1034IS8 does not include a shutdown pin; it remains active whenever the input voltage exceeds the regulation threshold.
