ADVANCE INFORMATION Data Sheet
ISL5640
June 2000 File Number 4657.3
3V Dual 8-Bit, 20/40/60MSPS A/D
Converter with Internal Voltage Reference
The ISL5640 is a monolithic, dual 8-bit 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 ISL5640
features a 9-stage pipeline architecture. The fully pipelined
architecture and an innovative input stage enable the
ISL5640 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.
The ISL5640 has excellent dynamic performance while
consuming less than 100mW power at 40MSPS. The A/D
only requires a single +3.0V power supply. Data output
latches are provided which present valid data to the output
bus with a latency of 5 clock cycles.
The ISL5640 is offered in 20MSPS, 30MSPS, 40MSPS and
60MSPS sampling rates.
