Description

The LTC2301/LTC2305 are low noise, low power, 1-/2-channel, 12-bit successive approximation ADCs with an I2C compatible serial interface. These ADCs include an internal reference and a fully differential sample-andhold circuit to reduce common mode noise. The LTC2301/ LTC2305 operate from an internal clock to achieve a fast 1.3μs conversion time.The LTC2301/LTC2305 operate from a single 5V supply and draw just 300μA at a throughput rate of 1ksps. The ADC enters nap mode when not converting, reducing the power dissipation.The LTC2301/LTC2305 are available in small 12-pin 4mm × 3mm DFN and 12-pin MSOP packages. The internal 2.5V reference further reduces PCB board space requirements.The low power consumption and small size make the LTC2301/LTC2305 ideal for battery operated and portable applications, while the 2-wire I2C compatible serial interface makes these ADCs a good match for space-constrained systems.ApplicationsIndustrial Process ControlMotor ControlAccelerometer MeasurementsBattery Operated InstrumentsIsolated and/or Remote Data AcquisitionPower Supply Monitoring
