Innovative architecture using 512 input comparators instead of the tradi- tional 1024 required by other flash converters reduces input capacitance and improves linearity. Inputs and outputs are ECL compatible, which makes the AD9060 the recommended choice for systems with conversion rates >30 MSPS to minimize system noise. An overflow bit is provided to indicate analog input signals greater than +VSENSE. Voltage sense lines are provided to ensure accurate driving of the ± VREF voltages applied to the units. Quarter point taps on the resistor ladder help optimize the integral linearity of the unit. The AD9060 is available in a 68-lead ceramic leaded (gull wing) chip carrier package specifically designed for low thermal imped- ances. Two performance grades for temperatures of both 0 °C to +70 °C and –55°C to +125°C ranges are offered to allow the user to select the linearity best suited for each application. Dynamic performance is fully characterized and production tested at 25 °C. |
