HA2557
Another choice for an I to V converter that takes better
advantage of the wide bandwidth of the HA-2557, is to use
the HA5023 Dual 100MHz current feedback amp. The opti-
mum bandwidth of a current feedback amp is obtained with a
fixed feedback resistor. Therefore scaling the I to V conver-
sion to a convenient value requires two stages. Fortunately
the HA5023 provides two wideband amplifiers in a single 8
pin Mini-DIP or SOIC package, while their current feedback
architecture provides signal gain with minimal reduction in
bandwidth. This circuit configuration is shown in Figure 8.
The optimum bandwidth is achieved in stage 1 with a 909
feedback resistor. This voltage is then gained up by the sec-
ond stage to provide a
±
4V Fullscale Voltage output with a
bandwidth in excess of 90MHz. The 10pF capacitor and the
additional 220
resistor improve gain flatness and reduce
gain peaking. The HA5023 also provides excellent Full
Power Bandwidth (-3dB at 80MHz for a 3.5V
P-P
signal).
Refer to Typical Performance Curves for more information.
