Description

The ADC088S022 is a low-power, eight-channel CMOS 8-bit analog-to-digital converter specified for conversion throughput rates 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 eight input signals at inputs IN0 through IN7.

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 ADC088S022 may be operated with independent analog and digital supplies. The analog supply (VA) can range from +2.7V to +5.25V, and the digital supply (VD) can range from +2.7V to VA. Normal power consumption using a +3V or +5V supply is 0.9 mW and 5.5 mW, respectively. The power-down feature reduces the power consumption to 0.03 µW using a +3V supply and 0.15 µW using a +5V supply.

The ADC088S022 is packaged in a 16-lead TSSOP package. Operation over the extended industrial temperature range of −40°C to +105°C is guaranteed.

Description:

The ADC088S022EVAL Design Kit (consisting of the ADC088S022 Evaluation Board and this User's Guide) is designed to ease evaluation and design-in of National Semiconductor's eight-channel, low-power CMOS Analog-to-Digital Converter (ADC088S022). In Stand-alone mode, suitable test equipment, such as a function generator and logic analyzer, can be used with the board to evaluate the ADC088S022. The Analog input signal enters the Analog-to-Digital Converter through one of its eight selectable input channels and is converted into a digital stream of bits by the ADC088S022.

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.
