Description

The HI5662 is a monolithic, dual 8-Bit, 60MSPS analog-todigital converter fabricated in an advanced CMOS process.

HI5662 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.

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.
