sample of the MAX1065AEUI. Remove the MAX1165 and install the MAX1065. The MAX1066 is a 14-bit version of the MAX1165, with an 8-bit interface. Its high-byte enable (HBEN) is on the pad labeled RESET. To evaluate the MAX1066, request a free sample of the MAX1066AEUP. Remove the MAX1165 and install the MAX1066, leaving U1 pins 1-4 and 25-28 unconnected. 2) With the power off, connect the -5VDC power supply between BUF-5 and AGND. See Table 2 for device comparison. 3) With the power off, connect the DC power supply ground return to AGND. Problem: no output measurement. System seems to report zero voltage, or fails to make a measurement. 4) Install a shunt across jumper JU3. Check AVDD and DVDD supply voltages. Check the 4.096V reference voltage using a digital voltmeter. Use an oscilloscope to verify the R/C, CS, and EOC signals. Ensure that a resistor is installed in socket R2; otherwise, the analog input is unconnected. 5) Apply analog input signal to BUFIN pad. If the full unipolar 0 to 5V rang
