Analog Devices AD8042 Dual‑Channel Rail‑to‑Rail Amplifier Datasheet
The AD8042 is a voltage‑feedback, high‑speed operational amplifier designed for single‑supply operation at +3 V, +5 V, or ±5 V. It offers rail‑to‑rail output swing, low power consumption (≈5.5‑6.4 mA per amplifier), and a 200 V/µs slew rate, making it suitable for video switchers, distribution amplifiers, and high‑speed ADC drivers.
The device is available in 8‑lead PDIP and 8‑lead SOIC packages. Detailed specifications include a 160 MHz -3 dB bandwidth, 39 ns settling time to 0.1 %, and input voltage range extending 200 mV below the negative rail. Typical performance graphs, layout recommendations, and application circuits such as composite video line drivers are provided.
