DESCRIPTION
13, 20, 26, 39, 44, 49, 50,
52
I
Analog negative supply voltage (ground). Pin 13 is internally connected to the heat slug
and lid (lid is also grounded internally).
21, 45, 48, 51
I Analog positive supply voltage
42
O Full-scale output current bias
23
I External clock input
22
I Complementary external clock
1, 3, 5, 7, 9, 11, 14, 24, 27,
29, 31, 33, 35, 37
I
LVDS positive input, data bits 13–0.
D13A is the most significant data bit (MSB).
D0A is the least significant data bit (LSB).
2, 4, 6, 8, 10, 12, 15, 25,
28, 30, 32, 34, 36, 38
LVDS negative input, data bits 13–0.
I D13B is the most significant data bit (MSB).
D0B is the least significant data bit (LSB).
17, 19
I Digital negative supply voltage (ground)
16, 18
I Digital positive supply voltage
43
I/O
Internal reference output or external reference input. Requires a 0.1-μF decoupling
capacitor to AGND when used as reference output.
46
O
DAC current output. Full-scale when all input bits are set '0'. Connect the reference side of
the DAC load resistors to AV_DD.
47
O
DAC complementary current output. Full-scale when all input bits are '1'. Connect the
reference side of the DAC load resistors to AV_DD.
41
Not connected in chip. Can be high or low.
40
I Asynchronous hardware power-down input. Active high. Internal pulldown.
