1FEATURES DESCRIPTION The ADC122S051/ADC122S051Q is a low-power, 2• Specified Over a Range of Sample Rates. two-channel CMOS 12-bit analog-to-digital converter • Two Input Channels with a high-speed serial interface. Unlike the • Variable Power Management conventional practice of specifying performance at a • Single Power Supply with 2.7V - 5.25V Range single sample rate only, the ADC122S051/ADC122S051Q is fully specified over a • Tested per AEC-Q100 and Qualified for sample rate range of 200 ksps to 500 ksps. The Automotive Applications converter is based on a successive-approximation • Meets AEC-Q100-011 C2 CDM Classification register architecture with an internal track-and-hold circuit. It can be configured to accept one or two input APPLICATIONS signals at inputs IN1 and IN2. • Portable Systems The output serial data is straight binary, and is compatible with several standards, such as SPI™, • Remote Data Acquisition QSPI™, MICROWIRE, and many common DSP • Instrumentation and Control Systems serial interfaces. KEY SPECIFICATIONS The ADC122S051/ADC122S051Q operates with a single supply that can range from +2.7V to +5.25V. • DNL: +0.7 / −0.4 LSB (typ) Normal power consumption using a +3V or +5V • INL: ± 0.50 LSB (typ) supply is 3.0 mW and 10 mW, respectively. The power-down feature reduces the power consumption • SNR: 72.5 dB (typ) to just 0.14 µW using a +3V supply, or 0.32 µW using • Power Consumption: a +5V supply. – 3V Supply: 3.0 mW (typ) The ADC122S051/ADC122S051Q is packaged in an – 5V Supply: 10 mW (typ) 8-lead VSSOP package. Operation over the industrial temperature range of −40°C to +85°C is specified.
