Hi to all,
I have a parallel ADC TLV1571 from Texas Instruments.
These are the pins 1.DS 2.WR 3.RD 4.CLK 5.DGND 6.DVDD 7.INT/EOC
8.D0 9.D1 10.D2 11.D3 12.D4 13.D5 14.D6 15.D7 16.D8/A0 17.D9/A1
18.CSTART 19.REFP 20.REFM 21.AGND 22.AVDD 23.AIN 24.NC.
I need it with my MCU. But 1st i want check it out with Analog inputs on my BBoard. Even i'hv tried it but seems i cant get it.
my connections are
5 and 6th pins to ground and vcc. all D0 to D7 with 8 LEDS. 21 AND 22's are vcc and ground. 23rd is VIN i've given 4.5v analog input through a pot. when i gave all these connections all my LEDs are glowing even when i disconnect AIN pin. even If i vary the AIN pot there is no sign of change.
Pls help me to come out. If you have any doubt from my ques pls ask me.
