3-1/2 Digit Auto-ranging A/d Converter With Triplex Lcd Drive And Display Hold Function Technology

The TC815 is a 3-1/2 digit integrating Analog-to-digital converter with triplex LCD Display drive and Automatic ranging. A Display hold function is on-chip. Input volt- age/ohm Attenuators ranging from 1 to 1/10,000 are automatically selected. Five full scale ranges are pro- vided. The CMOS TC815 contains all the Logic and Analog Switches needed to manufacture an auto- ranging instrument for ohms and voltage measure- ments. User selected 20mA and 200mA current ranges are available. Full scale range and decimal point LCD annunciators are automatically set in auto-range oper- ation. Auto-range operation is available during ohms (high and low power ohms) and voltage (AC and DC) measurements, eliminating expensive range switches in hand-held DMM designs. The auto-range feature may be bypassed allowing decimal point selection and input Attenuator selection control through a single line input. Expensive rotary switches are not required. During Manual mode operation, resolution is extended to 3000 counts full scale. The extended range opera- tion is indicated by a flashing 1 MSD. The extended resolution is also available during 200k and 2000V full scale auto-range operation. The Memory mode subtracts a reading, up to 5% of full scale from subsequent measurements. Typical applications involve probe resistance compensation for resistance measurements, tolerance measurements, and tare weight measurements. The TC815 includes an AC to DC converter for AC measurements. Only external Diodes resistors/ capacitors are required. By Microchip Technology Inc.
