The AD8328ARQ is a low cost, digitally controlled programmable gain amplifier designed for coaxial line driving applications, particularly for DOCSIS and EuroDOCSIS reverse path transmission systems. It accepts a differential or single-ended input and provides a differential output optimized for driving a 75 Ω load. The gain is programmed via an 8-bit serial word over an SPI interface, allowing precise 1 dB steps over a 59 dB range. Key performance characteristics include a low output noise density of 1.2 nV/√Hz at minimum gain, spurious-free dynamic range (SFDR) of -57.5 dBc at 21 MHz and -54 dBc at 65 MHz, and low distortion of -53 dBc at 65 MHz with 60 dBmV output. The device operates from a single 5V supply and over a temperature range of -40°C to +85°C. It features a sleep mode drawing 2.6 mA and a full power-down mode consuming only 20 µA. The AD8328ARQ is supplied in a 20-lead QSOP (SSOP) package with a 0.154" body width, suitable for surface mount assembly.
