Linear Technology LTC2309HF#TRPBF

Description
The LTC2309 is an 8-channel, 12-bit successive approximation ADC with an I²C compatible serial interface. It features low power consumption (1.5mW at 1ksps, 35pW in sleep mode), a fast conversion time (1.3µs), and low noise (SNR = 73.4dB). The ADC includes an internal reference, a fully differential sample-and-hold circuit, and an internal conversion clock. It operates from a single 5V supply and is available in both a 24-pin 4mm x 4mm QFN and a 20-pin TSSOP package.
