概述

Description

REF194GSZ-REEL7 is a precision voltage reference IC (the REF194 family) in a compact GSZ surface‑mount package, shipped on a 7-inch reel (REEL7) for automatic assembly. It provides a stable, low-noise reference voltage used to bias ADCs/DACs, instrumentation, and calibration circuits. Key points: low temperature coefficient and drift, low output noise, and good line/load regulation. The exact nominal Vref, accuracy, and drift depend on the specific REF194 variant—check the datasheet for the precise value and parameters. Typical applications include precision measurement, data acquisition systems, DAC/ADC references, and calibration equipment. For ordering, see the Digikey/Mouser listing to confirm the GSZ package and reel count.

Features

- Fixed output: 1.25 V reference
- Low-noise performance for ADC/DAC front ends
- Tight initial accuracy with low temperature drift
- Excellent line and load regulation
- Low quiescent current for power efficiency
- Wide operating temperature range
- Package: GSZ (SOT-23 family footprint)
- Packaging: REEL7 tape-and-reel for automated assembly
- Suitable for precision voltage reference in instrumentation, calibration, and precision ADC/DAC circuits

Package

Package: 6‑lead SC‑70 (SOT‑23‑6) package, reel packaging (GSZ).

Pinout

Pin count: 3 pins.
Function: Three-terminal fixed voltage reference with input (Vin), output (Vout), and ground (GND). The REF194 provides a stable reference voltage (nominally ~2.5 V) for precision circuits. The GSZ-REEL7 designation simply indicates the SOT-23 package on a reel.

Manufacturer

- Manufacturer: Analog Devices, Inc. (ADI)
- Company type: A multinational semiconductor company that designs and manufactures analog, mixed-signal, and digital signal processing integrated circuits (e.g., precision voltage references).

Application

REF194GSZ-REEL7 is a high-precision voltage reference. Common application areas include:
- ADC/DAC reference sources for precision data acquisition
- Analog front-ends in measurement and test equipment
- Calibration and traceability standards
- Sensor biasing and signal-conditioning networks
- Industrial process control and instrumentation
- Medical instrumentation requiring stable references
- Battery-powered handheld/portable instruments (low noise, low drift)
- References for precision regulators and op-amp circuits
