(LCD) with up to 10 common terminals and up to 40 segment terminals.
• Independent channel programming
• 4-channel ADC supplied by the internal voltage regulator
• 10-bit 460 Ksamples/sec. or 8-bit 660 Ksamples/sec. Successive Approximation Register
• ±2 LSB Integral Non Linearity, ±1 LSB Differential Non Linearity
• Integrated 4-to-1 multiplexer
• External voltage reference for better accuracy on low voltage inputs
• Individual enable and disable of each channel
• Multiple trigger sources
• Sleep Mode and conversion sequencer
• 40 segments and 10 common terminals display capacity
• Support static, 1/2, 1/3, 1/4, 1/5, 1/6, 1/7, 1/8, 1/9 and 1/10 Duty
• Support static, 1/2, 1/3, 1/4 Bias
• Power-save mode display
• Software-selectable low-power waveform capability
• Flexible frame frequency selection
