1 / 25 page ADC082S101 www.ti.com SNAS288C – APRIL 2005 – REVISED FEBRUARY 2010 ADC082S101 2 Channel, 500 ksps to 1 Msps, 8-Bit A/D Converter Check for Samples: ADC082S101 1 FEATURES APPLICATIONS 2 • Specified over a range of sample rates. • Portable Systems • Two input channels • Remote Data Acquisition • Variable power management • Instrumentation and Control Systems • Single power supply with 2.7V - 5.25V range DESCRIPTION The ADC082S101 is a low-power, two-channel CMOS 8-bit analog-to-digital converter with a high-speed serial interface. Unlike the conventional practice of specifying performance at a single sample rate only, the ADC082S101 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 one or two input signals at inputs IN1 and IN2. 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 ADC082S101 operates with a single supply that can range from +2.7V to +5.25V. Normal power consumption using a +3V or +5V supply is 3.2 mW and 9.6 mW, respectively. The power-down feature reduces the power consumption to just 0.12 µW using a +3V supply, or 0.35 µW using a +5V supply. The ADC082S101 is packaged in an 8-lead MSOP package. Operation over the industrial temperature range of −40°C to +85°C is guaranteed. 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.
