HI5662
Dual 8-Bit, 60MSPS A/D Converter with
Internal Voltage Reference
The HI5662 is a monolithic, dual 8-Bit, 60MSPS analog-to-
digital converter fabricated in an advanced CMOS process.
It is designed for high speed applications where integration,
bandwidth and accuracy are essential. The HI5662 reaches
a new level of multi-channel integration. The fully pipeline
architecture and an innovative input stage enable the HI5662
to accept a variety of input congurations, single-ended or
fully differential. Only one external clock is necessary to
drive both converters and an internal band-gap voltage
reference is provided. This allows the system designer to
realize an increased level of system integration resulting in
decreased cost and power dissipation.
The HI5662 has excellent dynamic performance while
consuming only 650mW power at 60MSPS. The A/D only
requires a single +5V power supply and encode clock. Data
output latches are provided which present valid data to the
output bus with a latency of 6 clock cycles.
For those customers needing dual channel 10-bit resolution,
please refer to the HI5762. For single channel 10-bit
applications, please refer to the HI5767.
