PRODUCT OVERVIEW

What Is the AD9833SRMZ-EP-RL7?

AD9833SRMZ-EP-RL7 is a low power, programmable waveform generator from Analog Devices capable of producing sine, triangular, and square wave outputs. This Enhanced Product (EP) version is designed to support defense and aerospace applications (AQEC standard)[reference:0] with controlled manufacturing baseline, 1 assembly/test site, 1 fabrication site, and enhanced product change notification[reference:1][reference:2].

The AD9833SRMZ-EP-RL7 features a 28-bit frequency register, allowing output frequency resolution of 0.1 Hz with a 25 MHz reference clock, or 0.004 Hz with a 1 MHz clock[reference:3]. The output frequency and phase are software programmable via a 3-wire SPI serial interface operating at clock rates up to 40 MHz, compatible with DSP and microcontroller standards[reference:4].

Operating from a 2.3 V to 5.5 V power supply with only 12.65 mW power consumption at 3 V, the device includes a power-down function (SLEEP) that allows unused sections to be powered down to minimize current consumption[reference:5]. The AD9833SRMZ-EP-RL7 is available in a 10-lead MSOP package with an extended temperature range of –55°C to +125°C[reference:6][reference:7].

Programmable Waveform Generation Sine, triangular, and square wave outputs with software programmable frequency and phase.

Enhanced Product (EP) Supports defense and aerospace applications with extended –55°C to +125°C temperature range and controlled manufacturing baseline.

Ultra-Low Power 12.65 mW power consumption at 3 V with power-down option for minimal current consumption.

Circuit Considerations for AD9833SRMZ-EP-RL7

Frequency & Phase Programming

The AD9833SRMZ-EP-RL7 is configured via a 3-wire SPI serial interface[reference:32]:

Frequency Registers: 28-bit wide FREQ0 and FREQ1 registers for programmable output frequency[reference:33]
Phase Registers: 12-bit wide PHASE0 and PHASE1 registers for programmable phase offset
Output Frequency Formula: f_OUT = (FREQREG / 2²⁸) × f_MCLK
Control Register: Configures output waveform type, power-down modes, and register selection
No External Components: The device requires no external components for waveform generation[reference:34]

PCB and Power-Supply Guidance

Waveform generator performance depends on layout, bypassing, and power supply quality:

Power Supply Decoupling: Connect 0.1 µF and 10 µF decoupling capacitors between VDD and AGND
CAP/2.5V Capacitor: Connect 100 nF decoupling capacitor from CAP/2.5V to DGND when VDD > 2.7 V; tie CAP/2.5V directly to VDD when VDD ≤ 2.7 V
COMP Pin: Used for decoupling the DAC bias voltage
Grounding: Use separate analog and digital ground planes for optimal performance
MCLK Input: The master clock determines output frequency accuracy and phase noise; use a low-jitter clock source
Verify the recommended PCB footprint from the official datasheet before production

Output frequency range (0–12.5 MHz)

Frequency resolution (28-bit)

Interface (3-wire SPI, up to 40 MHz)

Package (10-lead MSOP)

Temperature range (–55°C to +125°C)

Enhanced Product (EP) qualification

Family alternatives: AD9833BRMZ (standard version, –40°C to 105°C), AD9833WBRMZ-REEL (automotive AEC-Q100, –40°C to 105°C), AD9833SRMZ-EP-RL7 (Enhanced Product, –55°C to 125°C). For higher output frequency, consider the AD9834 (75 MHz with built-in comparator). For lower power, consider the AD9837 (8 mW, 2.3V to 5.5V). Select based on temperature range, qualification (EP/AEC-Q100), and packaging needs.
