AD9162BBCA

Overview

The AD9162BBCA is a 16-bit, single-channel RF digital-to-analog converter (DAC) from Analog Devices. It supports a minimum DAC update rate of 12 GSPS and direct RF synthesis at 6 GSPS. The device features a quad-switch architecture with a bypassable 2× interpolator filter, enabling operation in baseband, NRZ, or Mix-Mode up to 7.5 GHz. Key electrical parameters include ±2.7 LSB INL, ±1.7 LSB DNL, and programmable output current from 8 mA to 38.76 mA. It utilizes an eight-lane JESD204B SERDES interface and operates on 1.2 V and 2.5 V supplies within a -40°C to +85°C temperature range.

Feature Summary

• 16-bit resolution with 12 GSPS minimum update rate
• Mix-Mode operation supporting RF reconstruction up to 7.5 GHz
• Eight-lane JESD204B SERDES interface for flexible data input
• Programmable output current ranging from 8 mA to 38.76 mA

Applications

• Broadband communications systems
• DOCSIS 3.1 cable modem termination systems (CMTS)
• Wireless infrastructure (W-CDMA, LTE, LTE-A)
• Radar and jammer transmitters

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or the manufacturer directly. Confirm the specific suffix BBCA corresponds to the 169-ball, 11 mm × 11 mm CSP_BGA package with leaded balls as documented in the official ordering guide. Check for moisture sensitivity handling requirements prior to assembly.

Selection Notes

Select the AD9162BBCA when 16-bit resolution is required for high dynamic range applications. Ensure the system design accommodates the 169-pin package dimensions and thermal dissipation needs, which can reach approximately 2.65 W under high-performance conditions. Verify that the host processor supports the JESD204B protocol with sufficient lane count for the desired data rate.

Part Context

This component belongs to the AD9161/AD9162 family of high-speed RF DACs. While the AD9161 offers 11-bit resolution, the AD9162 provides 16-bit precision. Both share similar architectures and performance characteristics, making them suitable for demanding RF synthesis tasks where signal fidelity is critical.

Replacement Considerations

The AD9162BBCZ is a pin-compatible alternative within the same family, differing primarily in the use of lead-free solder balls instead of the leaded option found in the BBCA variant.
