LC89086M
8 Bit A/D Converter
Preliminary
Overview
The LC89086M is a low-power high-speed 8-bit serial-
parallel A/D converter fabricated in a high-speed CMOS
process.
Features
• Resolution: 8 bits (with an overflow output)
• Maximum conversion rate: 20M samples per second
• Error: Less than ±1.0 LSB
• Power supply: +5-V single-voltage power supply
• Power dissipation: 150 mW (typical)
• Analog input voltage range: VSS to VDD
• Digital output voltage: 3 state TTL level

Digital ground
Analog ground
Internal reference voltage (high) generation. Shorting this pin to VrefH (pin 5) generates a voltage of 2.0 V.
O This pin must be left open when the internally generated potential is not used.

7 Vref M
O Reference voltage intermediate level tap.
8 Vref L
I Reference voltage input (low)
9 Vref LO
Internal reference voltage (low) generation. Shorting this pin to VrefL (pin 8) generates a voltage of 0 V.
O This pin must be left open when the internally generated potential is not used.
