1 / 27 page ADC084S021 www.ti.com SNAS279E – APRIL 2005 – REVISED MARCH 2013 ADC084S021 4-Channel, 50 ksps to 200 Ksps, 8-Bit A/D Converter Check for Samples: ADC084S021 1 FEATURES DESCRIPTION 2 • Specified Over a Range of Sample Rates. The ADC084S021 is a low-power, four-channel • Four Input Channels CMOS 8-bit analog-to-digital converter with a high- • Variable Power Management speed serial interface. Unlike the conventional practice of specifying performance at a single sample • Single Power Supply with 2.7V - 5.25V Range rate only, the ADC084S021 is fully specified over a sample rate range of 50 ksps to 200 ksps. The APPLICATIONS converter is based upon a successive-approximation • Portable Systems register architecture with an internal track-and-hold circuit. It can be configured to accept up to four input • Remote Data Acquisition signals at inputs IN1 through IN4. • Instrumentation and Control Systems The output serial data is straight binary, and is KEY SPECIFICATIONS compatible with several standards, such as SPI™, QSPI™, MICROWIRE, and many common DSP • DNL: ±0.04 LSB (typ) serial interfaces. • INL: ±0.04 LSB (typ) The ADC084S021 operates with a single supply that • SNR: 49.6 dB (typ) can range from +2.7V to +5.25V. Normal power • Power Consumption consumption using a +3V or +5V supply is 1.6 mW and 5.8 mW, respectively. The power-down feature – 3V Supply: 1.6 mW (typ) reduces the power consumption to just 0.12 µW using – 5V Supply: 5.8 mW (typ) a +3V supply, or 0.35 µW using a +5V supply. The ADC084S021 is packaged in a 10-lead VSSOP package. Operation over the industrial temperature range of −40°C to +85°C is ensured. Table 1.
