AGND,
Exposed Paddle
Ground
Analog Ground. The exposed thermal paddle on the bottom of the
package provides the analog ground for the part. This exposed paddle
must be connected to ground for proper operation.
4 to 9, 11, 12, 55, 56, 58 DNC Do not connect. Do not connect to these pins.
10, 19, 28, 37 DRVDD Supply Digital Output Driver Supply (1.8 V Nominal).
49, 50, 53, 54, 59, 60, 63, 64 AVDD Supply Analog Power Supply (1.8 V Nominal).
ADC Analog
1 CLK+ Input ADC Clock Input—True.
2 CLK− Input ADC Clock Input—Complement.
51 VIN+A Input Differential Analog Input Pin (+) for Channel A.
52 VIN−A Input Differential Analog Input Pin (−) for Channel A.
57 VCM Output
Common-Mode Level Bias Output for Analog Inputs. This pin should
be decoupled to ground using a 0.1 μF capacitor.
61 VIN−B Input Differential Analog Input Pin (−) for Channel B.
62 VIN+B Input Differential Analog Input Pin (+) for Channel B.
Digital Input
3 SYNC Input Digital Synchronization Pin. Slave mode only.
