5 / 8 page AD9048 –5– REV. C PIN FUNCTION DESCRIPTIONS Burn-In Diagram Pin Description D1–D8 Eight digital outputs. D1 (MSB) is the most significant bit of the digital output word; D8 (LSB) is the least significant bit. AGND One of two analog ground returns. Both grounds should be connected together and to low impedance ground plane near the AD9048. DGND One of two digital ground returns. Both grounds should be connected together and to low impedance ground plane near the AD9048. VCC Positive supply terminals; nominally +5.0 V. VEE Negative supply terminals; nominally –5.2 V. CONVERT Input for conversion signal; sample of analog input signal taken on rising edge of this pulse. Pin Description RB Most negative reference voltage for internal reference ladder. RM Midpoint tap on internal reference ladder. RT Most positive reference voltage for internal reference ladder. VIN Analog input signal pin. NMINV “Not Most Significant Bit Invert.” In normal operation, this pin floats high; logic LOW at NMINV inverts most significant bit of digital output word [D1 (MSB)]. NLINV “Not Least Significant Bit Invert.” In normal operation, this pin floats high; logic LOW at NLINV inverts the seven least significant bits of the digital output word. |
