MAX628CPA+

Overview

The MAX628CPA+ is a precision voltage reference manufactured by Analog Devices Inc. under the Maxim Integrated brand, housed in an 8-pin PDIP package. It delivers a fixed output of +10V with high accuracy and low noise characteristics suitable for demanding applications. The device operates within a supply voltage range of 4.5V to 30V and supports load currents up to 15mA for both sourcing and sinking. It features extremely low temperature coefficients and excellent initial accuracy, ensuring stable performance across its specified operating temperature range of 0°C to +70°C.

Feature Summary

• Utilizes buried-zener technology to achieve exceptionally low noise performance
• Provides high-precision fixed voltage output with minimal drift over temperature
• Supports bidirectional load regulation for both source and sink current operations

Applications

• High-resolution analog-to-digital converter (ADC) reference circuits
• Precision data acquisition systems requiring stable voltage sources
• Instrumentation amplifiers and sensor signal conditioning stages

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific ordering suffixes match project requirements. Ensure storage conditions adhere to moisture sensitivity level guidelines to maintain long-term reliability and electrical performance integrity.

Selection Notes

Select this component when a stable +10V reference is required with low noise and high accuracy. Consider thermal management if operating near maximum power dissipation limits. Evaluate load regulation needs against the 15mA source/sink capability to ensure adequate drive strength for downstream circuitry without compromising reference stability.
