Description

General part information

LTC2309 Series

The LTC2309 is a low noise, low power, 8-channel, 12-bit successive approximation ADC with an I2C compatible serial interface. This ADC includes an internal reference and a fully differential sample-and-hold circuit to reduce common mode noise. The LTC2309 operates from an internal clock to achieve a fast 1.3μs conversion time.The LTC2309 operates from a single 5V supply and draws just 300μA at a throughput rate of 1ksps. The ADC enters nap mode when not converting, reducing the power dissipation.The LTC2309 is available in both a small 24-pin 4mm × 4mm QFN and a 20-pin TSSOP package. The internal 2.5V reference and 8-channel multiplexer further reduce PCB board space requirements.The low power consumption and small size make the LTC2309 ideal for battery-operated and portable applications, while the 2-wire I2C compatible serial interface makes this ADC a good match for space-constrained systems.ApplicationsIndustrial Process ControlMotor ControlAccelerometer MeasurementsBattery-Operated InstrumentsIsolated and/or Remote Data AcquisitionPower Supply Monitoring
