Unlike the conventional • Variable Power Management practice of specifying performance at a single sample rate only, the ADC124S101 is fully specified over a • Single Power Supply with 2.7V - 5.25V range sample rate range of 500 ksps to 1 Msps. The converter is based on a successive-approximation APPLICATIONS register architecture with an internal track-and-hold • Portable Systems circuit. It can be configured to accept up to four input signals at inputs IN1 through IN4. • Remote Data Acquisition • Instrumentation and Control Systems The output serial data is straight binary, and is compatible with several standards, such as SPI™, QSPI™, MICROWIRE, and many common DSP KEY SPECIFICATIONS serial interfaces. • DNL: +0.9/ −0.6 LSB (typ) The ADC124S101 operates with a single supply that • INL: ± 0.64 LSB (typ) can range from +2.7V to +5.25V. Normal power • SNR: 72.4 dB (typ) consumption using a +3V or +5V supply is 4.3 mW • Power Consumption and 13.1 mW, respectively. The power-down feature reduces the power consumption to just 0.14 µW using – 3V Supply: 4.3 mW (typ) a +3V supply, or 0.32 µW using a +5V supply. – 5V Supply: 13.1 mW (typ) The ADC124S101 is available in a 10-lead VSSOP package. Operation over the industrial temperature range of −40°C to +85°C. These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. Table 1.
