The AD9059 is a dual 8-bit monolithic analog-to-digital converter
VREF 2 27 GND
optimized for low cost, low power, small size, and ease of use.

To minimize system cost and power dissipation, the AD9059
D6A 8 21 D6B
includes an internal 2.5 V reference and dual track-and-hold
D5A 9 20 D5B
circuits. The ADC requires only a 5 V power supply and an
D4A 10 19 D4B
encode clock. No external reference or driver components are
D3A 11 18 D3B
required for many applications.
D2A 12 17 D2B
The AD9059’s single encode input is TTL/CMOS compatible
D1A 13 16 D1B D0A (LSB)
and simultaneously controls both internal ADC channels. The
14 15 D0B (LSB)
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 AD9059 is available in a space-saving 28-lead shrink small outline package (28-lead SSOP) and is specified over the industrial temperature range (–40°C to +85°C). Customers desiring single-channel digitization may consider the AD9057, a single 8-bit, 60 MSPS monolithic based on the AD9059 ADC core. The AD9057 is available in a 20-lead shrink small outline package (20-lead SSOP) and is specified over the industrial temperature range. REV.
