Detailed Description
Positive Reference Voltage Input Terminal. Bypass with a 0.33µF capacitor to GND as close to REFP
as possible.
Analog Supply Voltage. Bypass V
a 0.1µF capacitor.
Channel-IA Positive Analog Input. For single-ended operation, connect signal source to IAP.
Channel-IA Negative Analog Input. For single-ended operation, connect IAN to COM.
Analog Ground. Connect all GND pins to ground plane.
Conversion Clock Input. Clock signal for both receive ADCs and transmit DACs.
Channel-QA Negative Analog Input. For single-ended operation, connect QAN to COM.
Channel-QA Positive Analog Input. For single-ended operation, connect signal source to QAP.
Receive ADC Digital Outputs. AD9 is the most significant bit (MSB) and AD0 is the least significant
bit (LSB).
Output-Driver Ground
Output-Driver Power Supply. Supply range from +1.8V to V
combination of a 2.2µF capacitor in parallel with a 0.1µF capacitor.
Transmit DAC Digital Inputs. DA9 is the most significant bit (MSB) and DA0 is the least significant bit
(LSB). DA0–DA9 are internally pulled up to OV
Aux-ADC Digital Output
3-Wire Serial-Interface Data Input. Data is latched on the rising edge of SCLK.
3-Wire Serial-Interface Clock Input
3-Wire Serial-Interface Chip-Select/WAKE Input. When the MAX19711 is in shutdown, CS/WAKE
controls the wake-up function. See the Wake-Up Function section.
