The ADR01, ADR02, ADR03, and ADR06 are precision 10.0 V, 5.0 V, 2.5 V, and 3.0 V, respectively, band gap voltage references featuring high accuracy, high stability, and low power consumption. The devices are housed in tiny, 5-lead SC70 and TSOT packages, as well as in 8-lead SOIC version. The SOIC version of the ADR01, ADR02, and ADR03 are drop-in replacements1 to the industry-standard REF01, REF02, and REF03. The small footprint and wide operating range make the ADR01, ADR02, ADR03, and ADR06 references ideally suited for general-purpose and space-constrained applications.

With an external buffer and a simple resistor network, the TEMP pin can be used for temperature sensing and approximation. A TRIM pin is provided on the devices for fine adjustment of the output voltage.

The ADR01, ADR02, ADR03, and ADR06 are compact, low drift voltage references that provide a stable output voltage from a wide supply voltage range. The devices are available in 5-lead SC70 and TSOT packages and an 8-lead SOIC package with A, B, and C grade selections. All devices are specified over the extended industrial (−40°C to +125°C) temperature range. The ADR01, ADR02, ADR03, and ADR06 A grade in 8-lead SOIC are qualified for automotive applications.

Applications

  • Precision data acquisition systems
  • High resolution converters
  • Industrial process control systems
  • Precision instruments
  • Auto battery monitoring
  • PCMCIA cards

1 ADR01, ADR02, and ADR03 are component level compatible with REF01, REF02, and REF03, respectively. No guarantees for system level compatibility are implied. SOIC versions of ADR01, ADR02, and ADR03 are pin-to-pin compatible with the 8-lead SOIC versions of the REF01, REF02, REF03, respectively, with the additional temperature monitoring function.

Features and Benefits

  • Ultra-low distortion, high-resolution source
    • DC, 50Hz to 40kHz Frequency Range
    • Proprietary digital pre-distortion (DPD) algorithm
    • –130dBc THD @ 1kHz (typ.)
    • Arbitrary waveform generation (AWG) with on-board pattern memory
    • Differential (balanced) output up to 3.6VRMS
  • Fast pattern switching between multiple stored waveforms
  • Small form-factor (60mm x 40mm)
  • Low power, 1W typ. (quiescent)
  • SPI interface for integration into test and measurement systems

Product Details

The ADMX1002 is an ultra-low distortion sinewave and high-resolution arbitrary waveform generator. This high-performance module demonstrates a proprietary digital pre-distortion algorithm that reduces signal distortion below levels that can be achieved with high-performance digital-to-analog converters (DAC) and amplifiers alone. Its differential output can be set to common-mode levels often required to test high-performance analog-to-digital converters (ADC), audio codecs, and other audio ICs and systems. With an easy-to-use SPI interface and small-form factor, the ADMX1002 can be easily embedded into test systems, or simply used on the bench for measurement and characterization.

APPLICATIONS

  • High-end audio test
  • Analog-to-digital converter characterization and test
  • Sensor and transducer test
  • Frequency response and network analysis
  • ATE

Product Details

The ADMX1001 is an ultra-low distortion sinewave and high-resolution arbitrary waveform generator with an acquisition channel. This high-performance module demonstrates a proprietary digital pre-distortion algorithm that reduces signal distortion below levels that can be achieved with high-performance digital-to-analog converters (DAC) and amplifiers alone. Its differential output can be set to common-mode levels often required to test high-performance analog-to-digital converters (ADC), audio codecs, and other audio ICs and systems. The signal generator and the acquisition channel can be individually controlled using separate, easy to use, SPI interfaces - combined with the module's small-form factor, the ADMX1001 can be easily embedded into test systems, or simply used on the bench for measurement and characterization.

APPLICATIONS

  • High-end audio test
  • Analog-to-digital converter characterization and test
  • Sensor and transducer test
  • Frequency response and network analysis
