Pin Description
PIN NAME FUNCTION
1, 12, 13, 48 AVDD Analog Supply Voltage. Bypass each AVDD input pair (1, 48) and (12, 13) to GND with 0.1µF.
2 CMA Channel A Common-Mode Input-Voltage Reference
3 INA+ Channel A Positive Analog Input
4 INA- Channel A Negative Analog Input
5 SPEN Active-Low SPI Enable. Drive high to enable parallel programming mode.
6 REFIO
Reference Input/Output. To use internal reference, bypass to GND with a > 0.1µF capacitor. See
the Reference Input/Output (REFIO) section for external reference adjustment.
7 SHDN
Active-High Power-Down. If SPEN is high (parallel programming mode), a register reset is initiated
on the falling edge of SHDN.
8 I.C. Internally Connected. Leave unconnected.
9 INB+ Channel B Positive Analog Input
10 INB- Channel B Negative Analog Input
11 CMB Channel B Common-Mode Input-Voltage Reference
14 SYNC Clock-Divider Mode Synchronization Input
15 CLK+ Clock Positive Input
16 CLK-
Clock Negative Input. If CLK- is connected to ground, CLK+ is a single-ended logic-level clock
input. Otherwise, CLK+/CLK- are self-biased differential clock inputs.
17, 18 GND Ground. Connect all ground inputs and EP (exposed pad) together.
