CMOS 8-bit analog-to-digital converter with a high- • Four Input Channels speed serial interface. Unlike the conventional • Variable Power Management practice of specifying performance at a single sample rate only, the ADC084S051 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 KEY SPECIFICATIONS register architecture with an internal track-and-hold • DNL: ±0.09 LSB (typ) circuit. It can be configured to accept up to four input signals at inputs IN1 through IN4. • INL: + 0.12/ −-0.062 LSB (typ) • SNR: 49.6 dB (typ) The output serial data is straight binary, and is compatible with several standards, such as SPI™, • Power Consumption: QSPI™, MICROWIRE, and many common DSP – 3V Supply: 2.2 mW (typ) serial interfaces. – 5V Supply: 7.1 mW (typ) The ADC084S051 operates with a single supply, that can range from +2.7V to +5.25V. Normal power APPLICATIONS consumption using a +3V or +5V supply is 2.2 mW • Portable Systems and 7.1 mW, respectively. The power-down feature reduces the power consumption to just 0.12 µW using • Remote Data Acquisition a +3V supply, or 0.35 µW using a +5V supply. • Instrumentation and Control Systems The ADC084S051 is packaged in a 10-lead VSSOP package. Operation over the industrial temperature range of −40°C to +85°C is ensured. Table 1.
