Driving A-to-D Converters
T he AD8001 is well suited for driving high speed analog-to-
digital converters such as the AD9058. T he AD9058 is a dual 8-
bit 50 Msps ADC. In the circuit below two AD8001s are shown
driving the inputs of the AD9058 which are configured for 0 V
to +2 V ranges. Bipolar input signals are buffered, amplified
(–2
×
), 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 in Figure 48 reduces the number of ex-
ternal components required to create a complete data acquisi-
tion system. T he 20
resistors in series with ADC input are
used to help the AD8001s drive the 10 pF ADC input capaci-
tance. T he two AD8001s only add 100 mW to the power con-
sumption while not limiting the performance of the circuit.
