12-BIT SAR ADC LTC2309 8-Channel, 12-Bit SAR ADC 2 with I C Interface Fe Aut Rse Dse CRItp IOn ? n 12-Bit Resolution The LTC 2309 is a low noise, low power, 8-channel, 12-bit 2 n Low Power: 1.5mW at 1ksps, 35?W Sleep Mode successive approximation ADC with an I C compatible n 14ksps Throughput Rate serial interface. This ADC includes an internal reference n Low Noise: SNR = 73.4dB and a fully differential sample-and-hold circuit to reduce n Guaranteed No Missing Codes common mode noise.
