The unit is designed for low cost, high performance applications and requires only +5 V and an encode clock to achieve 40 MSPS or 60 MSPS sample rates with 10-bit resolution. The encode clock is TTL compatible and the digital outputs are CMOS; both can operate with 5 V/3 V logic, selected by the user. The two-step architecture used in the AD9050 is opti- mized to provide the best dynamic performance available while maintaining low power consumption. A 2.5 V reference is included onboard, or the user can provide an external reference voltage for gain control or matching of multiple devices. Fabricated on an advanced BiCMOS pro- cess, the AD9050 is packaged in space saving surface mount packages (SOIC, SSOP) and is specified over the industrial (–40 °C to +85°C) temperature range. The 60 MSPS version (AD9050BRS-60) is only available in the SSOP package. +5V 10 BITS 0.1µF 0.1µF 0.1µF ENCODE (2) 74AC574 3 4 10 5 6 9 1, 7, 12, 21, 23 13 2, 8, 11, 20, 22 AD9050 AIN (+3.3V ± 0.512V) +5V Figure 1.
