REF102AP

Overview

The REF102AP is a precision 10V voltage reference manufactured by Texas Instruments. It features a fixed output voltage of 10V with an initial accuracy tolerance of ±0.1%. The device operates within an input voltage range of 11.4V to 36V and provides a maximum output current of 10 mA. It exhibits a temperature coefficient of 10 ppm/°C and low noise characteristics of 5 µVp-p in the 0.1 Hz to 10 Hz frequency band. The component is housed in an 8-pin PDIP package and supports through-hole mounting. It functions reliably across an operating temperature range of -25°C to 85°C.

Feature Summary

• Provides a stable 10V fixed output voltage with high initial accuracy
• Engineered for low noise performance in the sub-Hertz frequency range
• Supports wide input voltage operation up to 36V
• Utilizes laser-trimmed technology for precise temperature stability

Applications

• High-precision analog-to-digital converter (ADC) reference sources
• Precision digital-to-analog converter (DAC) excitation circuits
• Calibration equipment requiring stable voltage standards
• Industrial instrumentation signal conditioning stages

Procurement Notes

Verify the specific suffix 'AP' to confirm the 8-pin PDIP package and through-hole mounting configuration, as other suffixes may indicate different packages or performance grades. Confirm that the 10 ppm/°C temperature coefficient meets your system requirements, as other variants like the C-grade REF102 may offer tighter drift specifications. Ensure the input voltage supply remains within the 11.4V to 36V operational window to maintain regulation. Check for end-of-life status or obsolescence notices from the manufacturer before finalizing procurement plans.

Selection Notes

Select the REF102AP when a fixed 10V reference is required with moderate temperature stability and through-hole compatibility. Consider alternative models if lower noise or tighter temperature coefficients are necessary, such as the REF100 series. Evaluate the 10 mA output current capability against load requirements to ensure adequate drive strength without external buffering. Verify that the 8-pin DIP footprint fits the target PCB layout constraints compared to surface-mount alternatives.

Part Context

The REF102 belongs to Texas Instruments' family of precision series voltage references designed for applications demanding high accuracy and stability. These devices typically utilize bandgap or buried Zener architectures to achieve low drift over temperature. The REF102 specifically targets systems needing a 10V standard, distinguishing it from other outputs like 2.5V or 5V in the same product line. It serves as a foundational component in measurement systems where reference integrity directly impacts overall system accuracy.
