The document describes the features and characteristics of Quad, 235 MHz, DC-Coupled VGA and Differential Output Amplifier AD8264 Rev. A.
The AD8264 from Analog Devices is a quad, DC‑coupled variable‑gain amplifier (VGA) that provides both single‑ended VGA output and a differential output buffer. It operates from a single supply of +2.5 V to +5 V and offers a gain range of 6 dB to 30 dB with linear‑in‑dB scaling of 20 dB/V.
Designed for applications such as multichannel data acquisition, PET imaging, ultrasound, and radar receivers, the device features low voltage‑noise (2.3 nV/√Hz) and low current‑noise (2 pA/√Hz), a small‑signal bandwidth of 235 MHz (VGA) and 80 MHz (differential), and a low power consumption of about 140 mW per channel at 3.3 V.
