AD8531/AD8532/AD8534 is a single-supply amplifier with a 250mA output current. The amplifier features 2.7V to 6V single-supply voltage range, 3MHz bandwidth and 5V/μs slew rate. It is suitable for audio, LCD driver, ASIC input or output amplifier and headphone driver applications
The AD8531/AD8532/AD8534 family provides single‑supply operation from 2.7 V to 6 V, rail‑to‑rail input and output, and high output drive of ±250 mA. Key features include a wide 3 MHz bandwidth, 5 V/µs slew rate, low 750 µA supply current per amplifier at 5 V, and very low input bias currents.
These amplifiers are offered in multiple surface‑mount packages: AD8531 in 8‑lead SOIC, 5‑lead SC70, and 5‑lead SOT‑23; AD8532 in 8‑lead SOIC, 8‑lead MSOP, and 8‑lead TSSOP; AD8534 in 14‑lead SOIC and 14‑lead TSSOP. Typical applications include audio drivers, LCD drivers, headphone amplifiers, and other low‑bias‑current circuits.
