IN
The KCW7836 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 40 MSPS speed is
made possible by a fully differential pipelined architecture
with an internal sample and hold.
• Low Power at 40 MSPS . . . . . . . . . . . . . . . . . . . . 225mW
• Wide Full Power Input Bandwidth . . . . . . . . . . . . 250MHz
• On-Chip Sample and Hold
• Fully Differential or Single-Ended Analog Input
• Single Supply Voltage. . . . . . . . . . . . . . . . . . . . . . . . . +5V
• TTL/CMOS Compatible Digital Inputs
The KCW7836 has excellent dynamic performance while
consuming only 225mW power at 40 MSPS. Data output
latches are provided which present valid data to the output
bus with a latency of 7 clock cycles. It is pin-for-pin
• CMOS Compatible Digital Outputs. . . . . . . . . . . . 3.0/5.0V
• Offset Binary or Two’s Complement Output Format
Applications
functionally compatible with the KCW7792 and the KCW7793.
• Professional Video Digitizing
• Medical Imaging
