Description
The HI5702 is a monolithic, 10-bit, analog-to-digital
converter fabricated in a BiCMOS process. It is designed for
high speed applications where wide bandwidth and low
power consumption are essential. Its 40 MSPS speed is
made possible by a fully differential pipeline architecture
which also eliminates the need for an external sample and
hold circuit. The HI5702 has excellent dynamic performance
while consuming <650mW power at 40 MSPS. Data output
latches are provided which present valid data to the output
bus with a latency of 7 clock cycles.
Refer to the HI5703, HI5746, or HI5767 data sheets for lower
power consumption.
