10-Bit, 20/40/60MSPS A/D Converter with
Internal Voltage Reference
The HI5767 is a monolithic, 10-bit, analog-to-digital
converter fabricated in a CMOS process. It is designed for
high speed applications where wide bandwidth and low
power consumption are essential. Its high sample clock
rate is made possible by a fully differential pipelined
architecture with both an internal sample and hold and
internal band-gap voltage reference.
The 250MHz Full Power Input Bandwidth and superior high
frequency performance of the HI5767 converter make it an
excellent choice for implementing Digital IF architectures in
communications applications.
The HI5767 has excellent dynamic performance while
consuming only 310mW power at 40MSPS. Data output
latches are provided which present valid data to the output
bus with a latency of 7 clock cycles.
The HI5767 is offered in 20MSPS, 40MSPS and 60MSPS
sampling rates.
