DC1337A

LINEAR TECHNOLOGY DC1337A Evaluation Module, 12Bit, 14KSPS, I2C, 8Channel, SAR Analog to Digital Converter

is a demonstration circuit for LTC2309 a low noise, low power, 8 channel, 12bit, 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 ADC enters nap mode when not converting, reducing the power dissipation. The internal 2.5V reference and 8 channel multiplexer further reduce PCB board space requirements. DC1337 demonstrates the DC performance of the LTC2309 in conjunction with the DC590B Quick Eval data collection board.
