Description

AD9838BCPZ-RL7 is a Direct Digital Synthesis (DDS) waveform generator from Analog Devices. It provides a programmable waveform output (sine, triangle, or square) with high spectral purity, controlled via a simple SPI-like serial interface. A clock input sets the reference; the output frequency is derived from the clock and a programmable frequency tuning word, enabling operation up to tens of MHz (clock-dependent). The device typically includes an on-chip DAC and requires an external load/conditioning network for the desired voltage output. It operates from a single supply (roughly 2.3–5.5 V) and comes in a RoHS-compliant BCPZ-RL7 package.
Key uses: function generators, RF test equipment, local-oscillator or IF sources in communications, tone generation, and lab/hobbyist signal generation.
Note: exact electricals (voltage/current output, clock range, pinout) depend on revision and package variant. Consult the latest Analog Devices datasheet for precise specifications and application circuits.

Features

AD9838BCPZ-RL7 features:
- Direct Digital Synthesis (DDS) device with programmable frequency and phase
- Three selectable waveforms: sine, triangle, and square
- SPI-like serial interface (clock, data, load) to program frequency, phase, and control bits
- External clock input to drive DDS (supports relatively high clock rates)
- Internal current-output DAC; external op-amp/resistors required to obtain a voltage output
- Power-down and software/hardware reset options
- Low jitter and good spectral purity for RF/test applications
- Wide supply range (compatible with common 2.3–5.5 V logic levels)
- Packaging: BCPZ, RoHS-compliant, RL7 tape-and-reel
Note: Exact DAC resolution and maximum output frequency depend on the clock and external circuitry.

Package

8-pin plastic SOIC (Small-Outline) package, RoHS-compliant, in tape-and-reel packaging (RL7).

Pinout

- Pin count: 28 pins.
- Function: It is a 1-channel direct‑digital synthesis (DDS) waveform generator. It uses a serial (SPI‑like) interface to program frequency, phase, and waveform. The device provides a current-output DAC (IOUT) which is typically converted to voltage with an external op-amp, and can generate programmable waveforms (e.g., sine/triangle/square depending on mode) for RF/local oscillator applications.

Manufacturer

- Manufacturer: Analog Devices, Inc. (ADI).
- What kind of company: An American multinational semiconductor company that designs and manufactures analog, mixed-signal, and digital signal processing ICs (including DDS devices like the AD9838).

Application

AD9838BCPZ-RL7 is a DDS-based waveform generator. Typical applications:
- Function generators and lab test equipment
- RF/microwave local-oscillator and signal sources
- Communications development and modulation testing
- Embedded systems and microcontroller signal generation
- Audio/ultrasound test signals and timing references
- Educational/demo boards and prototyping.
