SAN JOSE, Calif., April 22, 2014 /PRNewswire/ -- Engineers can achieve the
industry's highest resolution and fastest sampling rate at the lowest power
with the MAX11905, a  20-bit, 1.6Msps successive approximation register (SAR)
analog-to-digital converter (ADC) from Maxim Integrated Products, Inc.

Typically, when engineers require high-precision data conversion, they turn to
a delta-sigma ADC. However, to produce high precision and wide dynamic range,
those ADCs must consume at least 100mW of power. In contrast, the MAX11905 SAR
ADC consumes only 9mW—a 91% power savings. With this power savings comes very
high (20-bit) precision and the fastest sampling (1.6Msps) rate available. The
MAX11905 also integrates internal reference buffers, which reduces cost and
time to market, and saves up to 50% space compared to competitive discrete
solutions. With this versatility, the MAX11905 is ideal for a wide range of
applications, including process control, automatic test equipment, medical
instrumentation, and battery-powered devices.

Key Advantages

  oHigh speed: the MAX11905 enables 1.6Msps throughout with no latency and
    settling time limitation.
  oHigh performance: the ADC achieves 98.3dB signal-to-noise ratio (SNR) and
    -123dB THD; improves static and dynamic performance; guarantees monotonic
    function; and provides best-in-class power consumption.
  oVersatility: the SAR ADC delivers high 20-bit resolution with no missing
    codes, at 1.6Msps of speed, at 9mW of power, enabling flexibility in
    designs without compromises.
  oSimplified designs: the MAX11905 integrates internal reference buffers,
    reducing design time and cost.


  o"In the past, engineers used 24-bit delta-sigma ADCs to achieve fast
    acquisition with low noise and distortion," said Carmelo Morello, Senior
    Business Manager at Maxim Integrated. "With the MAX11905 SAR ADC, you can
    reach ultra-low-noise, ultra-low THD with low offset and gain drift, but
    now at less than 1/10 the power consumption and no settling time
  o"We need very high precision and ultra-low power in portable applications,
    especially in the industrial and medical markets," said Susie Inouye,
    Research Director at Databeans. "Products that merge these benefits will
    propel the next generation of portable devices."

Availability and Pricing

  oAvailable in a 20-pin, 4mm x 4mm TQFN package.
  oSpecified over the -40-degree Celsius to +85-degree Celsius temperature
  oPricing starts at $33.95 (1000-up, FOB USA).
