Dual 8-Bit, 60MSPS A/D Converter with
Internal Voltage Reference
Features
• Sampling Rate . . . . . . . . . . . . . . . . . . . . . . . . . . .60MSPS
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 configurations, 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.
• 7.8 Bits at f = 10MHz
IN
• Low Power at 60MSPS. . . . . . . . . . . . . . . . . . . . . 650mW
• Wide Full Power Input Bandwidth. . . . . . . . . . . . . 250MHz
• Excellent Channel-to-Channel Isolation . . . . . . . . . >75dB
• On-Chip Sample and Hold Amplifiers
• Internal Band-Gap Voltage Reference . . . . . . . . . . . . 2.5V
• Fully Differential or Single-Ended Analog Inputs
• Single Supply Voltage Operation . . . . . . . . . . . . . . . . +5V
• TTL/CMOS Compatible Digital Inputs
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.
• CMOS Compatible Digital Outputs. . . . . . . . . . . . 3.0/5.0V
• Offset Binary Digital Data Output Format
• Dual 8-Bit A/D Converters on a Monolithic Chip
Applications
• Wireless Local Loop
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.
