Overview
The AD9117BCPZN is a dual-channel, 14-bit low-power digital-to-analog converter (DAC) from Analog Devices. It operates at sample rates up to 125 MSPS with power dissipation of 232 mW at 125 MSPS and 191 mW at 10 MSPS. The device features differential current outputs adjustable from 2 mA to 20 mA and includes two on-chip auxiliary DACs. It supports flexible supply voltages ranging from 1.8 V to 3.3 V for analog and digital domains. Key performance metrics include an SFDR of 86 dBc at 1 MHz output and -162 dBc/Hz noise spectral density at 1 MHz output.
Feature Summary
- Dual 14-bit resolution with 125 MSPS maximum sampling rate
- Low power consumption: 232 mW at 125 MSPS, <3 mW in sleep mode
- Adjustable differential current outputs (2 mA to 20 mA)
- Integrated internal reference and two auxiliary DACs
Applications
- Wireless infrastructure base stations
- Picocell and femtocell systems
- Medical ultrasound transducer excitation
- Portable signal generators
Procurement Notes
Verify the specific suffix 'BCPZN' against the manufacturer's ordering guide to confirm package type and temperature range. Ensure compatibility with the required SPI interface voltage levels (1.8 V or 3.3 V) and analog supply requirements before procurement.
Selection Notes
Select the AD9117BCPZN when 14-bit resolution and dual-channel operation are required for low-power transmit paths. Compare against pin-compatible variants like the AD9114, AD9115, and AD9116 if lower resolution or cost constraints apply, as they share the same interface and footprint.
Part Context
The AD9117 belongs to the TxDAC family of dual low-power DACs. It is part of a pin-compatible series including the AD9114 (8-bit), AD9115 (10-bit), and AD9116 (12-bit). This design allows for easy migration between resolution levels while maintaining identical board layouts and software interfaces.
Replacement Considerations
Pin-compatible alternatives within the same family include the AD9114BCPZN, AD9115BCPZN, and AD9116BCPZN. These offer lower resolutions (8-bit, 10-bit, and 12-bit respectively) but maintain the same package and interface.
