Linear Technology LTC2351CUH-12#TRPBF

Description
The LTC2351-12 is a 12-bit, 1.5Msps ADC with six simultaneously sampled differential inputs. It operates on a single 3V supply, consumes only 5.5mA, and comes in a compact 32-pin (5mm x 5mm) QFN package. A Sleep shutdown mode further reduces power consumption to 12μW.
The LTC2351-12 features:
83dB common mode rejection
OV to 2.5V unipolar or ±1.25V bipolar differential input range
2.5V internal bandgap reference, can be overridden with external reference
3-wire SPI-compatible serial interface
Internal conversion triggered by CONV
SLEEP (12μW) and NAP (4.5mW) shutdown modes
