MAX146BEAP+ (MAXIM INTEGRATED PRODUCTS)

The MAX146BEAP+ is a +2.7V, low power, 8-channel, serial 12bit analogue to digital converter (ADC) in 20 pin SSOP package. This 12bit data acquisition system combine an 8-channel multiplexer, high bandwidth track/hold and serial interface with high conversion speed and low power consumption. The analogue inputs are software configurable for unipolar/bipolar and single ended/differential operation. This device use either the internal clock or an external serial interface clock to perform successive approximation analogue to digital conversion and have a reference buffer amplifier with a ±1.5% voltage adjustment range. It provides a hard wired SHDN (complimentary) pin, a software selectable power-down feature which can be programmed to automatically shut down at the end of a conversion. Accessing the serial interface automatically powers up the device and the quick turn-on time allows it to be shut down between all conversions.
