Pin Description
Detailed Description
The MAX19712 integrates a dual, 10-bit Rx ADC and a
dual, 10-bit Tx DAC while providing ultra-low power
and high dynamic performance at 22Msps conversion
rate. The Rx ADC analog input amplifiers are fully differ-
ential and accept 1.024VP-P full-scale signals. The Tx
DAC analog outputs are fully differential with ±400mV
full-scale output, selectable common-mode DC level,
and adjustable channel ID–QD offset trim.

NAME
FUNCTION
1
REFP
Positive Reference Voltage Input Terminal. Bypass with a 0.33F capacitor to GND as close to REFP
as possible.
2, 8, 11, 39,
41, 47, 51
VDD
Analog Supply Voltage. Bypass VDD to GND with a combination of a 2.2F capacitor in parallel with
a 0.1F capacitor.
3
IAP
Channel-IA Positive Analog Input. For single-ended operation, connect signal source to IAP.
4
IAN
Channel-IA Negative Analog Input. For single-ended operation, connect IAN to COM.
5, 7, 12, 40, 50
GND
Analog Ground. Connect all GND pins to ground plane.
6
CLK
Conversion Clock Input. Clock signal for both receive ADCs and transmit DACs.
9
QAN
Channel-QA Negative Analog Input. For single-ended operation, connect QAN to COM.
10
QAP
Channel-QA Positive Analog Input. For single-ended operation, connect signal source to QAP.
13–22
AD0–AD9
Receive ADC Digital Outputs. AD9 is the most significant bit (MSB) and AD0 is the least significant
bit (LSB).
23
OGND
Output-Driver Ground
24
OVDD
Output-Driver Power Supply. Supply range from +1.8V to VDD. Bypass OVDD to OGND with a
combination of a 2.2F capacitor in parallel with a 0.1F capacitor.
25–34
DA0–DA9
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 OVDD.
35
DOUT
Aux-ADC Digital Output
36
DIN
3-Wire Serial-Interface Data Input. Data is latched on the rising edge of SCLK.
37
SCLK
3-Wire Serial-Interface Clock Input
38
CS/WAKE
3-Wire Serial-Interface Chip-Select/WAKE Input. When the MAX19712 is in shutdown,
CS/WAKE
controls the wake-up function. See the Wake-Up Function section.
42
ADC2
Selectable Auxiliary ADC Analog Input 2
43
ADC1
Selectable Auxiliary ADC Analog Input 1
44
DAC3
Auxiliary DAC3 Analog Output (VOUT = 0 at Power-Up)
45
DAC2
Auxiliary DAC2 Analog Output (VOUT = 0 at Power-Up)
46
DAC1
Auxiliary DAC1 Analog Output (AFC DAC, VOUT = 1.1V at Power-Up)
48
IDN
Tx DAC Channel-ID Differential Negative Output
49
IDP
Tx DAC Channel-ID Differential Positive Output
52
QDN
Tx DAC Channel-QD Differential Negative Output
53
QDP
Tx DAC Channel-QD Differential Positive Output
54
REFIN
Reference Input. Connect to VDD for internal reference.
55
COM
Common-Mode Voltage I/O. Bypass COM to GND with a 0.33F capacitor.
56
REFN
Negative Reference Voltage Input Terminal. Rx ADC conversion range is ±(VREFP - VREFN). Bypass
REFN to GND with a 0.33F capacitor.
