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. n Applications n n n n Industrial Process Control
