Description
REF194GSZ-REEL7 is a fixed, precision voltage reference commonly used for accurate analog signaling. It delivers a stable reference voltage (typically 4.096 V) with low drift and low noise, making it suitable for ADC/DAC references, instrumentation, and calibration circuits. The GSZ suffix denotes the package style (a compact SOT-23/SC-70 three-pin device), and REEL7 indicates delivery on a 7-inch reel for automated assembly.
Key points:
- Fixed, high-stability reference with good line/load regulation and low noise
- Small, surface-mount package ideal for compact designs
- Suitable for precision measurement and calibration applications
- Operates over a defined temperature range with modest supply current
For exact electrical specs (initial accuracy, tempco, noise, load regulation, max supply, operating temperature) and detailed packaging data, consult the latest REF194 datasheet and the GSZ-REEL7 packaging documentation.
