Linear Technology LTC2309

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.

APPLICATIONS

n Industrial Process Control n Motor Control n Accelerometer Measurements n Battery-Operated Instruments n Isolated and/or Remote Data Acquisition n Power Supply Monitoring The LTC®2309 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 is available in both a small 24-pin 4mm × 4mm QFN and a 20-pin TSSOP package.
