Overview

  • Simultaneously Monitor Four Power Supplies
  • ±0.5% Threshold Accuracy Over Temperature
  • Selectable −4% and −6% Thresholds per Supply:
    5V, 3.3V, 2.5V, 1.8V, 1.5V, 1.2V, 1V and ±ADJ
  • Adjustable Reset (RST) Timeout
  • Overvoltage and Negative Voltage Monitoring
  • Push-Pull or Open-Drain RST Output
  • Margin Pin RDIS for Reset Disable
  • H-Grade Temperature Range
  • 16-Lead 3mm × 3mm QFN

The LTC2962 series of configurable power supply monitors can supervise systems with up to four supply voltages. One of 16 preset or adjustable voltage monitor thresholds per channel can be selected using external 1% resistors connected to the programming (PG) inputs. The preset voltage thresholds are accurate to ±0.5% over temperature. Positive (+ADJ) and negative (−ADJ) adjustable inputs with a 0.5V threshold allow undervoltage, negative voltage and overvoltage monitoring.

The watchdog (LTC2963 only) and reset timeout periods are adjustable using external capacitors. Accurate voltage thresholds and comparator glitch immunity ensure reliable reset operation without false triggering. The RST output is guaranteed to be in the correct state for VCC input voltage down to 1V.

The flexibility of the LTC2962 family provides the ability to monitor a wide variety of power supply combinations, including multiple supplies of the same voltage, with ±0.5% accuracy.

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 3.5VRMS
    • Fast pattern switching between multiple stored waveforms
  • Fully Differential input Acquisition Channel
  • Small form-factor (60mm x 40mm)
  • Low power, 1W typ. (quiescent)
  • SPI interface for integration into test and measurement systems

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
  • ATE
