The document provides a comprehensive specification sheet for the AD624, an instrumentation amplifier designed with external resistor gain programming. It covers part numbering conventions, including military-grade variants like the AD624SD/883B.
Key technical data includes absolute maximum ratings such as supply voltage limits and operating temperature ranges from -55°C to +125°C. The specifications table lists performance metrics for various gain settings (from 1 to 500), including gain error, input offset voltage, common-mode rejection ratio, and power supply current.
| Gain Equation | 40,000 + 20% |
|---|---|
| Storage Temperature Range | -65°C to +150°C |
