ADA4355ABCZ

Overview

The ADA4355ABCZ is a high-performance current input µModule from Analog Devices, integrating a transimpedance amplifier (TIA), analog filter, ADC driver, and a 14-bit ADC. It operates on a single 3.3 V supply with quiescent power at 546 mW when the internal LDO is enabled. The device features three selectable TIA gain settings: 2 kΩ, 20 kΩ, and 200 kΩ. It supports an ADC sampling rate up to 125 MSPS and outputs digitized signals via two serial LVDS data lanes operating at rates up to 1 Gbps per lane. The package dimensions are 12.00 mm × 6.00 mm CSP_BGA.

Feature Summary

• Integrates a complete current-to-bits data acquisition solution within a compact form factor.
• Features fast overdrive recovery and supports input pulse widths down to 10 ns for high spatial resolution.
• Includes selectable analog low-pass filters for noise reduction and antialiasing.

Applications

• Optical Time Domain Reflectometry (OTDR)
• Time of Flight (ToF) measurements
• Chemical analyzers
• Mass spectroscopy
• Reconfigurable optical add/drop multiplexers (ROADM)

Procurement Notes

Verify the specific ABCZ suffix against the manufacturer's ordering guide to confirm temperature range and packaging details. Ensure compatibility with the required SPI control interface and LVDS output standards before integration into the system design.

Selection Notes

Select this component for applications requiring precise current measurement and direct digital conversion in space-constrained environments. Evaluate the available TIA gain options to match the expected input current range and ensure the LPF bandwidth settings align with the signal frequency requirements.

Part Context

This part belongs to the ADA4355 series of programmable transimpedance receivers. It is designed as a self-contained module that eliminates the need for external discrete components typically required for high-speed current-to-digital conversion circuits.

Replacement Considerations

Check for other variants within the ADA4355 family or similar µModules from Analog Devices that may offer different gain configurations or package sizes while maintaining the same functional architecture.
