PRODUCT DESCRIPTION
The LTC®2309 is a low noise, low power, 8-channel, 12-bit
successive approximation ADC with an I 2C 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,whilethe2-wireI 2Ccompatibleserialinterfacemakes this ADC a good match for space-constrained systems.
