The Harris CA158 series includes several dual operational amplifiers (CA158, CA158A, CA258, CA258A, CA358, CA358A, CA2904) designed for single‑supply operation over a wide voltage range. They feature internal frequency compensation, low supply current and wide bandwidth, making them suitable for interface circuits, transducer amplifiers and general‑purpose op‑amp applications.
The datasheet provides absolute maximum ratings, operating conditions, thermal information, detailed electrical specifications, typical performance curves and a schematic diagram. It also includes package dimensions and metallization mask layout for PCB designers.
| High DC Voltage Gain | 100 dB (Typ) |
|---|---|
| Unity‑Gain Bandwidth | 1 MHz (Typ) |
| Supply Voltage Range (single supply) | 0.2 V to 30 V |
| Supply Voltage Range (dual supplies) | -1.5 V to +15 V |
| Low Supply Current | 1.5 mA (Typ) |
| Large Output Voltage Swing | 0 V to V+ –1.5 V |
The absolute maximum single‑supply voltage is 30 V, and the dual‑supply rating is up to +15 V.
Typical supply current is 1.5 mA, independent of the supply voltage within the recommended range.
The typical unity‑gain bandwidth is 1 MHz.
