AD9059BRSZ

Product Summary

The AD9059BRSZ is a dual 8-bit monolithic analog-to-digital converter optimized for low cost, low power, small size, and ease of use. With a 60 MSPS encode rate capability and full-power analog bandwidth of 120 MHz typical, the component is ideal for applications requiring multiple ADCs with excellent dynamic performance. To minimize system cost and power dissipation, the AD9059BRSZ includes an internal +2.5 V reference and dual track-and-hold circuits. The ADC requires only a +5 V power supply and an encode clock. No external reference or driver components are required for many applications. The AD9059BRSZ single encode input is TTL/CMOS compatible and simultaneously controls both internal ADC channels. The parallel 8-bit digital outputs can be operated from +5 V or +3 V supplies. A power-down function may be exercised to bring total consumption to < 12 mW when ADC data is not required for lengthy periods of time. In power-down mode the digital outputs are driven to a high impedance state. Fabricated on an advanced BiCMOS process, the AD9059BRSZ is available in a space saving 28-lead surface mount plastic package (28 SSOP) and is specified over the industrial (–40°C to +85°C) temperature range. The AD9059BRSZ can be applied in digital communications (QAM demodulators), RGB & YC/composite video processing, digital data storage read channels, medical imaging, and digital instrumentation.
