概述

Description

REF1933AIDDCT is a fixed-output precision voltage reference IC (DCT package) used to provide a stable reference for ADCs, DACs, and instrumentation. It delivers a tightly regulated, low-noise reference voltage that stays accurate across supply changes and temperature, enabling precise conversions and measurements. Typical features include a fixed output voltage (per variant), low temperature coefficient, low output noise, good line and load regulation, and modest quiescent current, with protection features as specified in the datasheet. Applications include ADC/DAC bias references, instrumentation and sensor interfaces, and portable/compact measurement systems. Use tips: supply from a clean source, place the recommended bypass capacitor close to the device, and follow the datasheet’s layout and decoupling guidance (and any enable/trim options). For exact voltage value, pinout, and electrical specs, consult the official REF1933AIDDCT datasheet.

Features

REF1933AIDDCT Features:
- Fixed 3.3 V output voltage
- Low-noise voltage reference
- Low drift / tight temperature coefficient
- Excellent line and load regulation
- Low quiescent current (micropower operation)
- Industrial temperature range suitable for harsh environments
- Small package option (DCT) for compact designs
- Ideal for precision references, ADC/DAC calibration, and sensor front-ends

Package

8-pin Small Outline Integrated Circuit (SOIC-8) package.

Pinout

- Pin count: 8 pins (8-pin package).
- Function: A fixed, precision voltage reference with an output buffer, providing a stable reference voltage for analog circuits (e.g., ADC/DAC applications; low noise and low drift).
