Technical specifications
| Specification | Value | Notes |
|---|---|---|
| Amplifier channels | 4 | |
| Single-supply operation | 3.3 V to 5.0 V | Operating-supply feature; electrical limits are specified at +5.0 V unless otherwise stated. This does not establish 3.3 V post-radiation characterization. |
| Dual-supply operation | ±1.65 V to ±2.5 V | |
| Enable grouping | Two amplifier pairs | |
| Ordered radiation assurance | 1 Mrad(Si) | Only the exact 5901-901-1S RHA ordering option; dose-rate conditions remain per datasheet. Published family dose rate: 50–300 rad(Si)/s. Irradiation bias and electrical-test supply conditions must follow the datasheet; no assurance at an uncharacterized voltage is implied. |
Values are subject to the conditions and ordering options in the referenced product documentation.
Product overview
The RHD5901 combines four operational amplifiers with enable controls that operate in pairs. Disabling a pair places those amplifiers in a power-down condition and their outputs in a high-impedance state. This supports signal paths in which several amplifiers feed a common output while inactive channels are disabled. Rail-to-rail input and output operation helps preserve usable signal range. The CMOS amplifiers support resistive and capacitive loads within the datasheet limits and are unity-gain stable under normal conditions. Ordering options define the screening flow and any radiation-assurance commitment for the selected part.
