	A SIMPLE ADC ON AN LTC1286 CHIP
by Yuri Magda Start ı The Software ı The Input Signal Handler and Interface ı Code Concerns ı The Design and Details ı Sources and PDF THE DESIGN AND DETAILS The design is assembled on a 5 ı 5 cm breadboard card. A flat cable about 30 cm long connects the board to the parallel port of the PC. The LTC1286 should be used with an analog ground plane and single-point ground techniques. You should tie the Gnd pin of the LTC1286 directly to the ground plane. The power supply voltage (5 V on pin 8 (V_CC)) must be kept free of noise and ripple by bypassing directly to the analog ground plane. The V_CC pin should be bypassed to the ground plane with a 1- to 10-ıF tantalum capacitor with leads as short as possible.
