The MAX4350/MAX4351 are dual supply op amps with 210MHz bandwidth and 485V/µs slew rate. They are available in ultra-small 5-pin SC70 and 8-pin SOT23 packages, and are suitable for low-power systems that require wide bandwidth, such as video, communications, and instrumentation.
The MAX4350 (single‑channel) and MAX4351 (dual‑channel) are unity‑gain‑stable voltage‑feedback amplifiers that operate from dual ±5 V supplies. They provide rail‑to‑rail outputs, a common‑mode input range that extends to the negative rail, and a quiescent current of only 6.9 mA per amplifier. These devices are targeted at video, communications, and instrumentation applications that require wide bandwidth and low power.
Key specifications include a 210 MHz -3 dB small‑signal bandwidth, 485 V/µs slew rate, and output swing to within 125 mV of either supply rail. The MAX4350 is offered in a 5‑pin SC70 package, while the MAX4351 uses an 8‑pin SOT‑23 package. Design guidelines recommend using isolation resistors (20‑30 Ω) when driving capacitive loads and keeping PCB traces short to preserve high‑frequency performance.
