The AD9101 is a high‑speed 125 MSPS sampling amplifier with 350 MHz bandwidth and low‑distortion performance.
The AD9101 sampling amplifier from Analog Devices provides extremely accurate, high‑speed sampling for 8‑ to 12‑bit A/D encoders. It features a monolithic track‑and‑hold architecture, a 350 MHz sampling bandwidth, and a 125 MSPS sampling rate, delivering low hold‑mode distortion and sub‑picosecond aperture jitter.
The device is offered in commercial and military temperature ranges, with options in plastic SOIC (AD9101AR) and ceramic LCC (AD9101AE, AD9101SE). It includes ESD protection, a wide supply voltage range, and configurable output offset, making it suitable for direct IF‑to‑digital conversion, high‑speed oscilloscopes, radar, and test equipment.
