This device consists of four independent voltage comparators that are designed to operate from a single power supply over a wide range of voltages. Operation from dual supplies also is possible as long as the difference between the two supplies is 2V to 28V and VCC is a least 1.5V more positive than the input common-mode voltage. Current drain is independent of the supply voltage. The outputs can be connected to other open-collector outputs to achieve wired-AND relationships.

AMP-PDK-EVM — 放大器性能開發套件評估模組
放大器性能開發套件 (PDK) 是一款評估模組 (EVM) 套件，可測試通用運算放大器 (op amp) 參數，並與大多數運算放大器和比較器相容。EVM 套件提供主板和多個插槽式子卡選項，可滿足封裝需求，使工程師能夠快速評估和驗證裝置性能。
AMP-PDK-EVM 套件支援五種最熱門的業界標準封裝，包括：
- D (SOIC-8 和 SOIC-14)
- PW (TSSOP-14)
- DGK (VSSOP-8)
- DBV (SOT23-5 和 SOT23-6)
- DCK (SC70-5 和 SC70-6)
