描述The ADS1000 is an I2C-compatible serial interface Analog-to-Digital (A/D) converter with differential inputs and 12 bits of resolution in a tiny SOT23-6 package. Conversions are performed ratiometrically, using the power supply as the reference voltage. The ADS1000 operates from a single power supply ranging from 2.7V to 5.5V.The ADS1000 performs conversions at a rate of 128 samples per second (SPS). The onboard programmable gain amplifier (PGA), which offers gains of up to 8, allows smaller signals to be measured with high resolution. In single-conversion mode, the ADS1000 automatically powers down after a conversion, greatly reducing current consumption during idle periods. The ADS1000 is designed for applications where space and power consumption are major considerations. Typical applications include portable instrumentation, consumer goods, and voltage monitoring.特性Complete 12-Bit Data Acquisition System in a Tiny SOT-23 PackageLow Current Consumption: Only 90µAIntegral Nonlinearity: 1LSB MaxSingle-Cycle ConversionProgrammable Gain Amplifier Gain = 1, 2, 4, or 8128SPS Data RateI2C Interface with Two Available AddressesPower Supply: 2.7V to 5.5VPin- and Software-Compatible with 16-Bit ADS1100APPLICATIONSVoltage MonitorsBattery ManagementIndustrial Process ControlConsumer GoodsTemperature MeasurementI2C is a trademark of NXP Semiconductors, Inc.
