ADC084S051 www.ti.com SNAS261F – NOVEMBER 2004 – REVISED MARCH 2013 ADC084S051 4 Channel, 200 ksps to 500 ksps, 8-Bit A/D Converter Check for Samples: ADC084S051 FEATURES 1 2 Specified Over a Range of Sample Rates. Four Input Channels Variable Power Management Single Power Supply with 2.7V - 5.25V Range KEY SPECIFICATIONS DNL: ±0.09 LSB (typ) INL: + 0.12/−-0.062 LSB (typ) SNR: 49.6 dB (typ) Power Consumption: – 3V Supply: 2.2 mW (typ) – 5V Supply: 7.1 mW (typ) APPLICATIONS Portable Systems Remote Data Acquisition Instrumentation and Control Systems DESCRIPTION The ADC084S051 is a low-power, four-channel CMOS 8-bit analog-to-digital converter with a highspeed serial interface. Unlike the conventional practice of specifying performance at a single sample rate only, the ADC084S051 is fully specified over a sample rate range of 500 ksps to 1 Msps. 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 ADC084S051 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 7.1 mW, respectively. The power-down feature reduces the power consumption to just 0.12 µW using a +3V supply, or 0...
