This custom ASIC converts an analog input into one of ten programmable ranges and displays the result on a 10 segment bar display. The input range is nominally 0V to 2.55V and is set by either an internal or external reference voltage. The voltage level for each range has a resolution of 8 bits and is stored in EEPROM. Display options include “Bar” or “Pointer” and can drive either LED or LCD type displays.
Features:
Internal 5V Regulator
Input Range = 0V to 2.55V
Internal or External Voltage Reference
10 Programmable Ranges
Resolution = 8 Bits
Linearity = ±1LSB
Internal Clock Oscillator
Temperature Range = -40°C to +85°C
