The ADA4530-1R-EBZ is an evaluation board for the ADA4530-1 offered in an 8-lead SOIC package. The ADA4530-1R-EBZ is a 4-layer printed circuit board (PCB) designed to minimize leakage currents with its guard ring features for femtoampere input bias current (IB) measurement.
The ADA4530-1R-EBZ is available in two default configurations: buffer (ADA4530-1R-EBZ-BUF) and transimpedance (ADA4530-1R-EBZ-TIA). Both boards are populated with the necessary passive components, banana jacks/terminal blocks for supply voltages, BNC/terminal blocks for the output voltage, multiple test pins, and metal shields. All components are placed on the primary side with the exception of the triaxial (triax)/coaxial (coax) input connector (J1) and SHIELD3.
The ADA4530-1R-EBZ also has unpopulated resistor and capacitor pads that allows quick prototyping with different configurations, such as noninverting gain and inverting gain.
Specifications for the ADA4530-1 are provided in the ADA4530-1 data sheet available from Analog Devices, Inc. The ADA4530-1 data sheet and the AN-1373 Application Note should be consulted in conjunction with this user guide when using the evaluation board.
