This is a stress rating only; functional operation of the device at these or any other conditions above those listed in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. 2Transient currents of up to 100 mA will not cause SCR latch-up. ORDERING GUIDE Model Linearity Error (LSB) 1 Package Options 2 Branding AD7887AR ±2 SO-8 AD7887AR AD7887ARM ±2 RM-8 C5A AD7887BR ±1 SO-8 AD7887BR EVAL-AD7887CB3 Evaluation Board EVAL-CONTROL BOARD 4 Controller Board NOTES 1Linearity error here refers to integral linearity error. 2SO = SOIC; RM = µSOIC. 3This can be used as a stand-alone evaluation board or in conjunction with the EVAL-CONTROL BOARD for evaluation/demonstration purposes. 4This board is a complete unit allowing a PC to control and communicate with all Analog Devices evaluation boards ending in the CB designators. |
