The REF50xxA-Q1 family of devices is low-noise, low-drift, very-high precision-voltage reference. These reference devices are capable of both sinking and sourcing, and are very robust with regard to line and load changes.

Excellent temperature drift (3 ppm/°C) and high accuracy (0.05%) are achieved using proprietary design techniques. These features combined with very low noise make the REF50xxA-Q1 family of devices ideal for use in high-precision data acquisition systems.

Each reference voltage is available in a standard-grade versions. The devices are offered in SO-8 packages and are specified from –40°C to 125°C.

DIP-ADAPTER-EVM — DIP 适配器评估模块

借助 DIP-Adapter-EVM 加快运算放大器的原型设计和测试，该 EVM 有助于快速轻松地连接小型表面贴装 IC 并且价格低廉。您可以使用随附的 Samtec 端子板连接任何受支持的运算放大器，或者将这些端子板直接连接至现有电路。

DIP-Adapter-EVM 套件支持六种常用的业界通用封装，包括：

  • D 和 U (SOIC-8)
  • PW (TSSOP-8)
  • DGK（MSOP-8、VSSOP-8）
  • DBV（SOT23-6、SOT23-5 和 SOT23-3）
  • DCK（SC70-6 和 SC70-5）
  • DRL (SOT563-6)
