AD9977BBCZ

Overview

The AD9977BBCZ is a dual-channel, 14-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It operates at sampling rates up to 250 MSPS and features an internal interpolation filter. The device utilizes a parallel data interface and delivers current outputs. It requires analog supply voltages of 3.3 V and 1.8 V, alongside digital supply options of 1.8 V or 3.3 V. The component is housed in a 164-lead BGA package and supports operation within a temperature range of -40°C to +85°C.

Feature Summary

• Dual-channel architecture with integrated 4x interpolation filtering for simplified system design
• High-speed 14-bit resolution supporting sample rates up to 250 MSPS
• Internal reference voltage source eliminating the need for external precision references
• Flexible power supply configuration accommodating standard 1.8 V and 3.3 V logic levels

Applications

• Wireless base station transmitters
• Test and measurement equipment signal generation
• Medical imaging systems requiring high dynamic range

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm pinout compatibility and electrical specifications. Ensure that the procurement channel provides valid RoHS compliance certificates. Confirm the package integrity upon receipt, as the BGA form factor requires careful handling during inspection and assembly processes.

Selection Notes

Select this component when a dual-channel solution with high linearity and internal interpolation is required. Compare performance metrics such as spurious-free dynamic range and power consumption against single-channel alternatives if space constraints allow. Verify that the host processor can support the necessary parallel data interface timing requirements for reliable operation at maximum speeds.

Part Context

The AD9977 belongs to the AD977x family of high-performance DACs from Analog Devices. This series is designed for applications demanding precise waveform generation and wide bandwidth. The BBCZ variant specifically denotes the lead-free BGA packaging option suitable for surface-mount assembly in industrial and communication infrastructure environments.

Replacement Considerations

Consult official cross-reference lists for verified substitutes. Potential equivalents may include other members of the AD977x family or newer generations from Analog Devices offering similar interpolation capabilities and pin configurations.
