The AD8001 is well suited for driving high-speed analog-to-digital converters, such as the AD9058.
The AD9058 is a dual 8-bit 50 Msps ADC. In the circuit shown, there are two AD8001s driving the in-puts of the AD905f8 which are configured for 0- to +2-V ranges. Bipolar input signals are buffered, amplified (-2x), and offset (by +1.0 V) into the proper input range of the ADC. Using the AD9058's internal +2-V reference connected to both ADCs (as shown) reduces the number of external com-ponents required to create a complete data acquisition system. The 20-Ω resistors in series with ADC input are used to help the AD8001 drive the 10-pf' ADO input capacitance. The two AD8001s only add 100 mW to the power consumption while not limiting the performance of the circuit.
The AD8001 is a low power, high-speed amplifier designed to operate on ±5 V supplies. The AD8001 features unique transimpedance linearization circuitry. This allows it to drive video loads with excellent differential gain and phase performance on only 50mW of power. The AD8001 is a current feedback amplifier and features gain flatness of 0.1 dB to 100 MHz while offering differential gain and phase error of 0.01% and 0.025°. This makes the AD8001 ideal for professional video electronics such as cameras and video switchers. Additionally, the AD8001's low distortion and fast settling make it ideal for buffer high-speed A-to-D converters.
The AD8001 offers low power of 5.5 mA max (VS = ±5 V) and can run on a single +12 V power supply, while being capable of delivering over 70 mA of load current. These features make this amplifier ideal for portable and battery-powered applications where size and power are critical. The outstanding bandwidth of 800 MHz along with 1200 V/µs of slew rate make the AD8001 useful in many general purpose high-speed applications where dual power supplies of up to ±6 V and single supplies from 6 V to 12 V are needed. The AD8001 is available in the industrial temperature range of 40°C to +85°C.
