•Four input channels
•Variable power management
•Single power supply with 2.7V - 5.25V range

Description

The ADC124S021 is a low-power, four-channel CMOS 12-bit analog-to-digital converter with a high-speed serial interface. Unlike the conventional practice of specifying performance at a single sample rate only, the ADC124S021 is fully specified over a sample rate range of 50 ksps to 200 ksps. The converter is based on a successive-approximation register architecture with an internal track-and-hold circuit. It can be configured to accept up to four input signals at inputs IN1 through IN4.

The output serial data is straight binary, and is compatible with several standards, such as SPI™, QSPI™, MICROWIRE, and many common DSP serial interfaces.

The ADC124S021 operates with a single supply that can range from +2.7V to +5.25V. Normal power consumption using a +3V or +5V supply is 2.2 mW and 7.9 mW, respectively. The power-down feature reduces the power consumption to just 0.14 µW using a +3V supply, or 0.32 µW using a +5V supply.

The ADC124S021 is packaged in a 10-lead MSOP package. Operation over the industrial temperature range of −40°C to +85°C is guaranteed.

Description:

The ADC124S021 is a 2.2 mW, CMOS 12-bit, 200 KSPS Analog-to-Digital converter offered in a 10-lead SOT-23 package.

This ADC Design Kit, consisting of one ADC124S021 evaluation board and WaveVision4 hardware, is designed to ease the evaluation and design-in of these National Semiconductor Analog-to-Digital Converters. These evaluation boards allow the designer to evaluate product performance in a choice of two ways: in standalone mode with a logic analyzer and appropriate software (including National's WaveVision software), or with a personal computer and WaveVision4 hardware and software.

Features:

  • Specified over a range of sample rates.
  • Four input channels
  • Variable power management
  • Single power supply with 2.7V - 5.25V range

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
