Function
Selects the source for the VDRIVE voltage.
In Position A, connects VDRIVE to DVDD.
In Position B, takes VDRIVE from the external connector J5.
Selects the source for the external reference.
In Position A, selects the on-board AD780.
In Position B, selects the external connector J4.
When using an external reference, LK14 and LK15 should be in place to connect the reference pins to the external reference
source.
See LK14.
Selects the source for the DVDD supply.
In Position A, selects the 96-way connector (EVAL-CONTROL BRD2) as the source.
In Position B, selects the external connector J7 as the source.
Selects whether the analog input is taken from the on-board op amps or directly from the external connector J3.
In Position A, selects the op amps.
In Position B, selects J3.
Inserting LK18 terminates the analog input applied to J2 with a 50 Ω resistor.
Selects the source for the AVDD supply.
In Position A, selects the 96-way connector (EVAL-CONTROL BRD2) as the source.
In Position B, selects the external connector J6 as the source.
Selects the source for the +12 V supply.
In Position A, selects the 96-way connector (EVAL-CONTROL BRD2) as the source.
In Position B, selects the external connector J8 as the source.
Selects the source for the −12 V supply.
In Position A, selects the 96-way connector (EVAL-CONTROL BRD2) as the source.
In Position B, selects the external connector J8 as the source.
Selects the source of CS input.
In Position A, sources CS from the external connector J11.
In Position B, connects CS to the 96-way connector.
Selects the source of RD input.
In Position A, sources RD from the external connector J12.
In Position B, connects RD to the 96-way connector.
Selects the source of WR input.
In Position A, sources WR from the external connector J13.
In Position B, connects WR to the 96-way connector.
N/A
Inserting LK26 terminates the analog input applied to J3 with a 50 Ω resistor.
