The ADA4356 is a low-noise, wide dynamic-range, current input, analog-to-digital converter (ADC) μModule. For space savings in size conscious applications, the ADA4356 includes all the required active and passive components to realize a complete current-to-bits data-acquisition solution with programmable gain and filter characteristics.

The high-speed transimpedance amplifier (TIA) front-end amplifier in the ADA4356 supports 20ns pulse widths, which allows high spatial resolution for the ToF measurements, and exhibits fast overdrive recovery from large input signals. The ADA4356 includes three selectable TIA feedback resistor values for programmable TIA gain.

An internal analog low-pass filter offers either 100MHz or 1MHz cutoff frequencies to reduce broadband noise and serve as an anti-aliasing filter for the ADC inputs. For lower bandwidth signals, the 1MHz filter configuration offers additional noise reduction.

Following the TIA and filter blocks, a 14-bit pipeline ADC converts the analog signal at 125MSPS and outputs the digitized signals through two serial, low voltage, differential signaling (LVDS) data lanes operating at rates up to 1GBPS per lane. The data clock output (DCO) operates at frequencies of up to 500MHz and supports double data rate (DDR) operation.

Product Details

The EVAL-ADA4356EBZ evaluation board is designed to evaluate the performance of the ADA4356, a single-channel, low-noise, wide dynamic-range, current input, analog-to-digital converter (ADC) μModule with three programmable gains and two selectable internal analog low-pass filters, offered in a 12mm × 6mm BGA package. It provides access to the ADA4356’s features through ADI’s Analysis | Control | Evaluation (ACE) software.

The EVAL-ADA4356EBZ evaluation board is designed for use with the Digilent ZedBoard via the field programmable gate array (FPGA) mezzanine card (FMC) connector.

The notable features which the EVAL-ADA4356EBZ evaluation board supports are as follows:

Low voltage digital signaling (LVDS) data output interface.
Programmable gain transimpedance amplifier (PGTIA), low-pass filter (LPF), and ADC configuration via serial peripheral interface (SPI) and secure shell (SSH).
On-board generation of 3.3V regulated supplies that power the board’s main circuitry, as well as other regulated supplies: 2.5V, 1.8V.
Multiple on-board input options for ease of evaluation.
Level shifters for flexibility on choice of FPGAs.

The EVAL-ADA4356EBZ evaluation board is a 6-layer printed circuit board (PCB) with dimensions of 3.957in × 2.717in. Figure 1 shows the board’s front and back view. The EVAL-ADA4356EBZ evaluation board comes populated with key circuits and components that allow for a straight-forward bench setup, which minimizes the need for additional bench top equipment.
