Microchip Technology TC7107A
The TC7107A drives common anode light emitting diode (LED) displays directly with 8 mA per segment. The TC7106A low-power drain and 9V battery operation make it suitable for portable applications. The TC7106A/TC7107A reduces linearity error to less than 1 count.FEATURES
:● Internal Reference with Low Temperature Drift: - TC7106/TC7107: 80 ppm/°C (Typical) - TC7106A/TC7107A: 20 ppm/°C (Typical)
● Drives LCD (TC7106) or LED (TC7107) Display Directly
● Zero Reading with Zero Input
● Low Noise for Stable Display
● Auto-Zero Cycle Eliminates Need for Zero Adjustment
● True Polarity Indication for Precision Null
