ADS7142
ADS7142 超低功耗、超小型 12 位 SAR ADC
制造商:TI
产品信息
描述The ADS7142 autonomously monitors signals while maximizing system power, reliability, andperformance. It implements event-triggered interrupts per channel using a digital windowedcomparator with programmable high and low thresholds, hysteresis, and event counter. The deviceincludes a dual-channel analog multiplexer in front of a successive approximation registeranalog-to-digital converter (SAR ADC) followed by an internal data buffer for converting andcapturing data from sensors.The ADS7142 is available in 10-pin QFN package and consumes only 900 nW of power. Thesmall form-factor and low power consumption make this device suitable for space-constrained and/orbattery-powered applications.特性Standalone, Nanopower Sensor Monitor for cost-sensitive designsSmall Package Size: 1.5 x 2mmEfficient Host Sleep and Wake-upAutonomousMonitoring at 900 nWWindowed Comparator for Event-triggered HostWake-upData Buffering during Host SleepIndependent Sensor Configuration and Calibration Dual-Channel, Pseudo-Differential, or Ground-Sense InputConfiguration Programmable Thresholds for CalibrationInternal Calibration improves Offset and Drift False Trigger PreventionProgrammable Thresholds per ChannelProgrammable Hysteresisfor Noise ImmunityEvent Counter for Transient Rejection Deep Data AnalysisData Buffer for Fault DiagnosticsHigh Precision Mode for16-bit AccuracyOne-Shot Mode for Fast Data Capture I2C™ InterfaceCompatible from 1.65 V to 3.6 V8 ConfigurableAddressesUp to 3.4 MHz (High Speed) Wide Operating RangeAnalog Supply: 1.65 V to 3.6 VTemperature Range: –40°Cto 125°C All trademarks are the property of their respective owners.
