Low Power, 8.5 mW, 2.3 V to 5.5 V,

Programmable Waveform Generator

AD9837

FEATURES

GENERAL DESCRIPTION

Digitally programmable frequency and phase

8.5 mW power consumption at 2.3 V

MCLK speed: 16 MHz (B grade), 5 MHz (A grade)

28-bit resolution: 0.06 Hz at 16 MHz reference clock

Sinusoidal, triangular, and square wave outputs

2.3 V to 5.5 V power supply

3-wire SPI interface

Extended temperature range: −40°C to +125°C

Power-down option

The AD9837 is a low power, programmable waveform generator

capable of producing sine, triangular, and square wave outputs.

Waveform generation is required in various types of sensing,

actuation, and time domain reflectometry (TDR) applications.

The output frequency and phase are software programmable,

allowing easy tuning. The frequency registers are 28 bits wide:

with a 16 MHz clock rate, resolution of 0.06 Hz can be achieved;

with a 5 MHz clock rate, the AD9837 can be tuned to 0.02 Hz

resolution.

10-lead LFCSP

The AD9837 is written to via a 3-wire serial interface. This serial

interface operates at clock rates up to 40 MHz and is compatible

with DSP and microcontroller standards. The device operates

with a power supply from 2.3 V to 5.5 V.

APPLICATIONS

Frequency stimulus/waveform generation

Liquid and gas flow measurement

Sensory applications: proximity, motion,

and defect detection

Line loss/attenuation

Test and medical equipment

The AD9837 has a power-down (sleep) function. Sections of the

device that are not being used can be powered down to minimize

the current consumption of the part. For example, the DAC can

be powered down when a clock output is being generated.

Sweep/clock generators

Time domain reflectometry (TDR) applications

The AD9837 is available in a 10-lead LFCSP_WD package.
